Attn: Gary Key/ASUS...Please address Wifi/Bluetooth issues - Asus Transformer TF700

Gary Key/ASUS:
I was hoping that you could come on here and address the Wifi/Bluetooth issues that the Infinity has...the same issues that the TFP and 300T also suffer from. ASUS has been quick to address some issues lately, such as the I/O problem, so I was hoping there could be some dialog about the progress or outlook for this issue too.
The issue I am talking about, just in case someone might not have heard, is the issue with the BT and Wifi where the Wifi connection degrades to nearly unusable, or drops out entirely, when you are connected and streaming data to a device via BT. Some examples of this would be playing Pandora and streaming to Bluetooth headphones, or even out to your Home Theatre receiver. When I do this, my internet connection drops from 24Mbps to 2.5Mbps, and then it trails off from there as I let Pandora/IheartRadio/Streaming Radio play...there are intermittent cutouts, the speed trails down to under 1Mbps, and then at some point completely shuts down the Wifi. Personally this is my biggest issue with this tablet, and it was the only reason I returned my TFP(3x), and it is especially frustrating given how lacking the stock speaker on the Infinity is...the tablet volume doesn't get 'loud', and the speaker is facing away from me.
So given the recent firmware update addressing and fixing some of the Infinity's issues, I was hoping you could update us about the progress or prognosis for this BT/Wifi issue...is this something that will ever be fixed, or is this something that Transformer 300T/Prime/Infinity owners need to accept??
My other question, which is more important IMO is...since I think I know the answer to the above question...is there any chance that you can have ASUS add support for USB BT dongles?? This was recently discussed in another thread, with someone questioning whether or not a USB BT dongle could be plugged into the keyboard USB port, and be used for the BT so that it is used instead of the internal BT, therefore bandaiding out of the issue and being able to use BT without having the Wifi dropout. I have tried it, and presently the dongle is not recognized, and I could not find any apps anywhere to get it to work...unfortunately. If I were able to get this to work...either internally or via dongle(sucks having to settle)...I would have ZERO issues with my Infinity, but as of right now this is still a huge issue for me and I am still contemplating returning it and waiting for something that works as it should.
I know you are a busy man, and I appreciate the work you do and how you personally address customers and there issues on here, and I am just respectfully asking you if you could revisit this issue...this time for the Infinity. And especially address the dongle workaround.
Thank you.

From what I read it is hardware issue.
wifi and BT sharing same antenna.

I have read the same, and given that the issues persist with the Prime 8 months after release, I don't expect it to be fixed...but would like to see the issue addressed a bit further.
But really the thread should have been titled something more like 'Attn: Gary K/ASUS: Please add USB BT Dongle support'...as that is the more important part of this thread, as I am fairly certain that if this could be fixed with the hardware 'as-is', it would already have been on the Prime and 300T. The thread is more of a request for dongle support...dongles are less than $5 on eBay, and I would be happy to plug one into my USB port when I want to stream via BT to headphones/stereo, if that is what I have to do to maintain my Wifi connection speed and avoid fallout.

Almost all devices have BT and wifi share an antenna.

I can confirm the WiFi issue.
My wifi goes from max (full blue) signal to a grey wifi symbol. When it does, I have to disconnect wifi and reconnect and it works again for some time.
I haven't used BT yet.

iPad 3's are affected by this problem as well.
I think it has something to do with Bluetooth and Wifi transmitting off the same 2.4GHz spectrum. Try adjusting your router settings as according to what these folks did to resolve their issue.

Lets hope Gary from Asus is also looking into the OTA issues that some of the TF700's are having. This OTA thing is something most stand tablet customers are not expecting nor would they be likely to find a site like XDA there at least some user solutions are available.

Is your wife doing exactly what you're trying to do on your Infinity, that is stream video over wifi with the device while listening to the audio over paired Bluetooth?
How is your router setup at home? Are you broadcasting b/g/n?

I tried my infinity watching Netflix and listening to my jambox. Low resolution and choppy then stops. Then I took my wife's ipad3 and did the samething. Perfect. I have a Linksys E4200v2 with 9dbi antennas and I was 5 feet away from my router which since I called Comcast about my connection has improved to 32mbps. I set my wifi to 2.4ghz only, N only, 20-40mhz and wpa2 security. I sent the infinity back to B&H for a refund. Figured it was hardware problem. I will be buying another one but I do feel hesitant which isn't a good thing. I like the Infinity but I want to be able to watch and listen to music without choppy sound and resolution. For $600 that's what I want from my Infinity. I will try with the next one.
I tried channel 1,6 & 11 but I got better performance from auto

I can't believe more people aren't concerned with this issue, esp given how inept the onboard speaker is.

I'm having the same problem and think it should be addressed too.

I found my bt dongles but I hope if they do come up with something that its a nice half moon shaped Bluetooth dongle that fits along side the dock because the one I have sticks out like a sore thumb
1/2 inch.

Dude, I hear you loud and clear! I've been taking heat for months trying to just warn people about this but everyone who is in denial just comes back and says nothing is wrong. The people in denial will just tell you their tablet is perfect and everything plays perfect. Just before, sitting outside trying to watch some old TV shows on Netflix and couldn't get 10 seconds of clear video when using a small external BT speaker. MAN that is just frustrating. And YES, my ipad does NOT have this issue. My connection speed goes from 24mb/s to 1.9mb/s. I may as well just turn the tablet off. All the Asus tablets you buy will have this same problem...so when you get your new one you can test it if you like but it will have the same issue. Don't wait to long to return it.

I own a Samsung galaxy nexus and a galaxy tab 10.1. Both of the devices playback videos without Bluetooth audio lag. My newly purchased Infinity has at least a 2 second audio delay. This issue needs to be addressed now. If Asus cannot come forward with a fix, I will have to return this tablet. I do not see a dongle as an acceptable fix when my other devices don't need one.

no problems
I just got my tab 3 days ago. I watched Netflix while using a Bluetooth stereo headset with no lag audio nice and synced and great video quality.

Your lucky you have one without the defect. Yes, the Wifi/Bluetooth fallout issue has been around since the original released prime. My original prime had the issue, regardless of any sort of antenna mod. Another prime I bought sometime later didn't have any Wifi/Bluetooth fallout issue. I have went through two TF700's atm. First, had the issue along with some screen defects. I returned it. Second, no screen defects and no WIFI/Bluetooth fallout issue. My personal judgement is that its not and issue that can be fixed via any sort of software/firmware fix. I believe it is hardware. Something to do with the quality of chips they are using or something else (my guess). Asus has not come clean on the issue and I don't think they ever will. My advice would be to return the tablet and try another. GL

Ditto. I am streaming Netflix right now to my LG bluetooth headphones. Zero lag and zero dropout. I was not able to do this with the Prime.

So, I'm guessing you guys can watch YouTube without audio lag too? Looks like mine is going back.

Interesting. I just tried it. Youtube lagged considerably. Audio and video were not in sync. Went back to Netflix - watching Jim Gaffigan stand-up comedy and audio and video were perfectly in sync.

Bluetooth problems

I've been having bluetooth problems with this phone since day 1 & I'm wondering if it's just my phone or if anyone else is having the same experience. No matter what rom or headset I use, I get a craptastic connection. I don't have any problems pairing devices, but I can't get 10 feet away from the phone without it disconnecting and I can't even turn my head without the audio cutting out. It also randomly disconnects for no reason & sometimes won't reconnect until I reboot. This has happened with every rom I've tried & every headset too. I've bought & returned multiple headsets thinking it was just my Blueant, but it happens with every one.
Could I have a faulty unit or does the bluetooth on this phone really suck this bad? I listen to podcasts & music all day long at work so I need to have a decent connection. Opinions needed please.
I think it may be a bad phone.
I have and used the following bluetooth devices:
Plantronics 590A
Jawbone Icon and Era
BlueAnt S4 which I use in the car. And auto connects before I sit down to drive when I have it on.
Sony Ericsson MW600
And Jabra Pro 9470 (office phone setup that connects to my phone via bt)
All connects without a problem. Have you done a titanium backup and perform a factory reset? And after the reset use titanium backup to restore app and data only and leave the system settings alone. You can restore the wifi stuff if you like. From there that's like a fresh install. Hope that works for you.
Yeah I've done many, many wipes & fresh installs & nothing helps. I don't have any problems connecting, I just have problems STAYING connected & listening to audio. It cuts out constantly without me even touching the phone. I've never had such shoddy bluetooth on any other device.
*sigh* Looks like I may be doing an exchange...

Well before leaving the store...if you are going to a brick and mortar to do the exchange, bring the bt headset with you and try it out there and try to replicate the problem with a new phone.
I do not have range problems but I don't usually have my phone more than 5 ft way from me when talking on it via bt.
I have a replacement on the way for bluetooth problems,people complained of a horrid background noise and the range was maybe 8 feet before major static would kick in

My BT sounds like crap! People say it sounds like I'm in a wind tunnel or they can't hear me that well, when they speak to me it cuts in and out.
This is when I connect to my Parrot BT in my truck. I know its not the Parrot system because my HD2 works fine with it.

I have a Dual car stereo & now that I think about it, everyone says they can't hear me even though I installed the mic on the side column & it's no more than a foot from my face at any time. Aargh this is so annoying. Freaking $600 phone & my damn $25 RAZR from Big Lots has better bluetooth.
If I bring it to the store, would they exchange it for me? I ordered it directly from T-Mobile, I didn't get it in a store.

No you will have to call T-Mobile and do a warranty exchange. I have no problems with BT on my phone at all.

a few threads about bluetooth problems
So whats the deal? Has anyone been able to fix the BT problems with this phone yet?
Can we flash a different BT.apk file or something?
Somebody by now should have some answers I would think.
My parrot system in my truck suck ass with this phone. Always cutting in and out.
Streaming audio is fine its the talking to people I'm have problems with.

horrid bluetooth sound quality
it seems a lot of people have been having issues with the bluetooth sound quality. i have mine paired with a motorola HF850 car kit, which has bluetooth v1.1, or something like that. i wonder if the problem is with backward compatibility, as people seem not to have as many issues with newer devices. would flashing a different radio potentiall help this problem? is it possible to downgrade the bluetooth version with a custom ROM? any other thoughts on ways to address this issue?

Bluetooth audio lag

Hi,
i have bluetooth Logitech Mini Boombox speaker, and i can say i am pretty disappointed.
Listening to mp3 and music in overall is OK, of course.
The problem is with video. Both BSplayer and Dice player give me a lag when watching movies.
Very hard to watch people speak as lip syncing is off.
Can anyone with bluetooth speakers try some movie and let me know the results.
Maybe some other video player plays better. Maybe it is Boombox that has problems (but i doubt).
Thing to have in mind: i tried playing from internal storage and streaming...both audio streams lag.
Aslo: the new firmware doesn't help.
Is this maybe normal for Android in overall? Shouldn't be.
Thx
Check out this thread maybe it can help

If it makes you feel any better this problem is universal across multiple devices. It drives me crazy. It is present on the Transformer prime, TF300 Acer a510 and my Excite 7.7 even though these devices use different BT radios and different BT versions. I have heard people claim that some of these devices don't have video slowdown with BT. They do. Its subtle in some cases and might be overlooked but its there.
I have to assume it is OS related or Tegra related as these are the only things these devices have in common. I have found no way to completely minimize the slowdown in video. I have gone back to using wired headphones for video and BT for music and audio only where sync isn't a factor.
Here is one thing that does help. If you are playing a video that has AC3 audio encoding (most downloaded MKV files) the delay is increased slighty because the audio decoding is done by software not hardware - the video is delayed slightly to keep it in sync with the audio as it is decoded. Over BT this delay, for whatever reason is further exagerated.
For the record: ALL video players on Android decode AC3 in software, even Diceplayer - there is NO hardware support for AC3 on the tegra 3 chip.
To speed up your video you can try this: download the free software Avidemux. Use it to convert only the audio of your MKV file to AAC. By doing this you alow both audio and video to be decoded by hardware - this reduces a major source of lag. On a core i7 PC converting the audio to AAC takes less than 2 minutes on most videos. The video is left untouched - it is not re-encoded.
How to use Avidemux:
In the VIDEO drop down box select: COPY
In the AUDIO drop down box select: AAC
in the CONFIGURE box select a bitrate: 160 or whatever you prefer.
In the FILTERS box select Stereo for the Mixdown. (Why stereo? If you are listening through two speakers keep it simple - two channels are fastest to decode.)
In the FORMAT box select MP4.
In the FILE menu select SAVE then SAVE VIDEO and name your video with an MP4 extension. It will begin converting and will likely take only a couple of minutes on a fast machine.
Now you may find that your video plays fast enough to be acceptable over BT. I still find a faint lag noticeable even with full hardware decoding of audio.

You sure all these devices use different radios or wifi/bt chipsets? The TF700 uses the BCM4329, a very common (and now pretty cheap) chipset that does Wifi, BT (2.1 EDR only) and FM. I'd guess a lot of other Tegra 3 devices uses that one as well. If they'd gone with the BCM4330 they would have BT 4.0 and probably 5GHz wifi as well. The BCM4329 supports this, but it requires antennas for it.
According to someone from Asus (someone here mentioned they'd contacted support about it) BT and wifi shares antennas (makes sense, they're both in the same frequency range) which can cause a lot of interference which leads to abysmal performance, especially for the wifi.
All I know for sure is I'll stick to wired headphones with this tablet...

So it doesn't bother you at all dropping half or more of thousand US dollars on a tablet you can't use wifi and bluetooth correctly? It is this type of atitude that makes Asus get away with things like this and not want to make better products. If they know people will just continue to buy their products, even with known defects and issues, they're not going to change anything except charge higher prices for you to pay. So sad.
Hi,
i will try the trick and change audio stream, just because i want to know if it gets any better.
I am not going to do this every time I know I'll watch a movie on my infinity.
Fortunately my bluetooth speaker also has a line-in jack, so i have a workaround, but i could do that on any f*****.. speaker also. Wouldn't need a bluetooth one
Anyway, just wanted to let everyone interested know, that i have tried same movie with wifi on and off - same result.
This means, yes BT and WIFI share antenna, but if that would be a primary problem, wouldn't it be only logical that when wifi is off, bluetooth gets better. And vice versa. Well, for me that is not the case, which means there is an obvious SW problem. Could be Asus, could be Android. That's the main question here now.
Did this problem get any better with custom roms on TF300?
Thx

No, it does bother me, just not enough to RMA it. I pretty much just use wired headphones at the moment so I can live with it.
I could complain to Asus directly through their support form, but the last time I complained about I/O issues and ANR messages when browsing they suggested I enable software rendering in Internet Explorer 9.
I could RMA it, wait for months and then receive a tablet with the exact same flaw. Unless Asus can say that they've fixed the issue and you can get it replaced within days, I'm not RMA-ing anything. And that's not very likely to happen, is it?
Mixed results
So after reading this thread I decided to try it. I tried it with my bluetooth sound bar and netflix was stuttering, it would have to buffer and when it worked the video was choppy but the sound on the soundbar was fine. But then when I tried it with mine jay bird bluetooth headphones it works seamlessly kind of weird how one Bluetooth device wouldn't work but another one would.

Bluetooth has been screwed up on so many devices for so long - with video slowdown on every Tegra based device I have owned - but it hasn't gotten a lot of attention. So I'm glad to see that it bugs other people too.
This problem was present even on my Tegra 2 based Galaxy Tab 10.1 and Motorola Xoom. So I've been pretty surprised to find exactly the same problem on the latest generation of devices.
It bothered me so much I took an sd card with videos and my BT headset down to Best Buy and Microcenter and tried every device they had, with the intention of buying the one that didn't demonstrate Video slowdown when listening through BT headphones. There weren't any.
I will say that with the Jaybird Freedom BT headset the problem is almost imperceptible, but when you switch to wired heaphones, you CAN notice the difference.Videos run faster and smoother. With BT there is just the slightest general slowdown which I find distracting.
Custom ROMs have never solved the problem for me either. Overclocking has also been suggested, but the TF700 should have a fast enough processor to handle anything I would think. So I kind of think the OS is to blame.
I've learned to love wired headphones and speakers again. I keep telling myself the audio quality is better anyway, while I try not to trip over the headset cord and flip my tablet across the room....
Does the iPad use the BCM4330 chipet? I know it features Bluetooth 4.0. It is ironic that Apple cheapens out on the camera, storage space, and connectivity, but gives a superior wifi/bluetooth chipset. I would be curious what the price difference between the two chipsets is. You would think Asus would be want to be competitive and advertise Bluetooth 4.0. The standard has existed for 2 years.

Thus I concluded that streaming music over BT to a speaker or headset had no problems or slow downs at all. So I decided to test with video. For this I used Amazon Prime Instant Video.
Wifi speed with BT off and no streaming: 9.6-9.8 Mbps.
Wifi speed with BT off and streaming video on APIV: 6.5-7.8 Mbps
Wifi speed with BT on and streaming video on APIV: 6.5-7.8 Mbps
Wifi speed with BT on and streaming video on APIV with audio going to Jambox: 6.7-7.9 Mbps
Now I think that the BT + streaming final test result being faster was not significant. I ran it at least 3 times to confirm and it was within those limits.
So at least for my personal copy of the Infinity, I am not seeing a WiFi slowdown while streaming over BT. I don't have 40+ Mbps internet, so maybe the slowdown is only at very high speeds and high radio power requirements.

Just to add another data point. My Prime will stream movies with Bluetooth with no sync issues or excessive buffering and has been like that since the day I got it. I'm unlocked and running a custom ROM (AW2.1). My Prime's WiFi is pretty solid (for a prime LOL) and my GPS is DOA.
I have been a big bluetooth audio fan (I stay up late watching movies frequently but am courteous to the rest of the family) for a while and one thing I have found is some headphones lag no matter what is transmitting. A reviewer will very often not notice it if they just listen to music. I've been using my GOgroove Wireless AirBands as my TF201 'phones, FWIW.
It's not an OS or hardware thing, it's a bluetooth thing. Some apps (like Youtube) simply compensate for this audio lag when using bluetooth (and Airplay as well, btw). You can see it yourself, when you pause the youtube video, it will take a fraction of a second for the sound to pause. I haven't seen an A2DP connection (on iOS as well) that didn't have this lag. Video apps need to compensate for it (Netflix did too, at least for iOS and Airplay, don't know for bluetooth either on iOS or Android), so different players may have this problem or not.
What it's worse for though, is for games. That jambox video where the guy is playing a game is just BS.

I hade the prime too.
I have two sony bluetooth music headsets (the mw600 and the hbh-ds220). Both were working with the prime without any problem.
Now with my new tf700 i get stuttering when listening to google music. The music is buffered on the tf700 and it even happens when i have no internet connection. So i don't think it's an antenna problem at all.
i also noticed lag when using bsplayer and youtube when i tried to connect the tf700 to my beamer and stream the audio via bluetooth. bsplayer was worse but i noticed it also in the youtube app. I don't know if it would start stuttering too as i disconnected bluetooth immediatly.
I think the stuttering was a little bit less when i go on max performance. But that's just a subjective opinion.
I think it's a problem with the bluetooth chip itself and thus i have to send it back...
Anyone know if the Jelly Bean update for the TF300 fixed this?
FYI, Asus tech support told me that the bluetooth audio lag issues "will be improved" in a future OTA. I read that as "not completely fixed" so I returned (sniff sniff) my TF700 today while I still could.

Yeah, none on my SGS3 or iPad2 (BT 2.1 even), but I really wanted an integral keyboard with extra battery for those long flights to Asia.
Kinda hoping the Lenovo S2110 can fit the ticket, but might wait for another round of processors...

Bad sound quality through Bluetooth

I'm having bad sound quality when making call through Bluetooth in my car. It sounds like the audio is breaking up. Anybody else have this problem? My note 3 was working just fine through bluetooth
Sent from my One using XDA Premium 4 mobile app
I also noticed the same thing yesterday driving home. I did not have this problem earlier in the week. I'm not sure what is going on. This along with a strange wifi problem has recently surfaced. If I leave my wifi range and then return, it does not want to reconnect. I have to toggle the airplane mode then wifi will reconnect. I am running stock 11s rooted with 2.7.1.0 TWRP, Xposed framework, Xpoxed GEL, Gravity Box, Tasker, Autovoice.

I am. I'm looking for suggestions for things to try and improve the stuttering/skipping/dropouts that I'm experiencing when using my OnePlus One in media playback mode through my Chevrolet MyLink car radio. I have some additional details to offer and things I have tried:
1) The playback application doesn't seem to make any difference, the problem is most pronounced (unlistenable) when playing back music files and is highly annoying when listening to speech (e.g. podcast) files. I suspect the difference is the music having a beat that gets interrupted while there are some normal pauses in speech so the stuttering blends in a bit more. In any event, it's not a problem with the playback application.
2) It seems unlikely to be a problem with the car radio (Chevrolet MyLink). Though I haven't done extensive testing I have done some using my old Motorola Atrix HD with a nightly CM11 on it from a few weeks back and that does not seem to have the issue, or at least it is not nearly as severe.
3) When I use a third party bluetooth audio receiver (some cheap no-name one from ebay) the quality seems to be fine but when I try to go directly to the car stereo I get tons of stuttering/skipping/drop outs.
A friend suggested that I try running an alternative kernel and see if that improves things. Any ideas on whether that may be the case or which one might be the best to try? Any other suggestions? It's quite annoying that I can't playback audio through the car radio...
Thanks!
Anyone have any ideas? I tried running the Franco kernel tonight and it seems to have the same issue. I did some logcat captures and I seem to be getting a lot of "W/bt-btif ( 2104): btif_media_aa_prep_2_send congestion buf count 24" messages when playing back audio through the car radio. See the attached full logcat captures with both the stock and Franco kernels and connected to both an alternative Bluetooth dongle and to the MyLink car radio.
Any suggestions?
After further testing I was able to determine this is an issue with the phone and not the car radio as I was able to find at least one other BT device which exhibits the same issue. I have created a ticket for this issue at: https://jira.cyanogenmod.org/browse/BACON-1005 if you are also experiencing this issue you are encouraged to go and vote for the ticket.
One question though. Do you have WiFi on when traveling in your car? Try turning it off and see if you still get skipping.
I do in fact have WiFi on at all times. I tried turning it off for the day today while doing some driving and it appeared to clear up the problem. I would think it's still a bug because having WiFi on should not prevent BT audio from working correctly but it at least gives someone a direction to investigate.
So I've done some slightly longer term testing and what I can say is the problem is not totally cleared up when WiFi is off but it is much, much better (definitely listenable). I will still get a couple dropouts when first starting a stream (sometimes, not always) but after 30 seconds to a minute it seems to settle down and be fine as long as I keep the WiFi off.

Just to clarify the situation..
My Xperia Z2 have the same issues.. It is not your phone but the Bluetooth stack in android that pretty much sucks the problems you are dicribing has been there since android 4.2 on a lot of devices.
I have just changed my Lumia 1020 out with this Z2 and call me disappointed in music quality! On the Lumia you would have trouble hearing a difference between jack/auxiliary and Bluetooth..
And today I did notice some dropouts even with WiFi off well into my drive but it was just a few packets I would guess more of an annoyance than a serious problem. I've heard about issues in the Android BT stack but the confusing part of that is why certain devices (such as my Atrix HD) don't seem to experience the problem.
I have a bluetooth stereo I use every morning in my home and a bluetooth stereo in my car. I almost exclusively use pandora, but I have also used power amp on longer trips. I have never experience this issue with my opo. I have ran 25-33 all rooted with no problems and am currently using CM11 nightlies. I also am not having any wifi issues.
Sorry it's not very helpful, but it doesn't sound like a widespread issue at least.
It certainly has something to do with the particular bluetooth implementation used by the receiver interacting with the OPO. As I indicated I have three different BT receivers I can test with and the problem affects two of them but not the other.

Weak Bluetooth?

Anybody else experiencing a weak bluetooth connection with the S6? I'm losing the connection with my Garmin Vivosmart in places I've had no problem connecting with other devices. I'm curious about other's experiences on this as a search hasn't turned up much yet.
I have noticed this as well. I could walk pretty far away from my S4 before it would drop. With this S6, I only get a few feet away before audio gives out. Doesn't disconnect, just loses audio.
Also, random loss of audio from time to time, even when the phone is right next to my head.
Yeah I've noticed the same thing with my S6. At work I don't always keep my phone on me and with my M8 I could walk around the whole building without my G Watch disconnecting and with my S6 I can only get a few feet away before the connection drops.
Yes happening with my moto 360 it is annoying and hopefully will be fixed soon
Haven't had any disconnect issues, but for some reason connecting to my car stereo has been a nightmare. It takes like 5 tries before it actually connects.

I'm having issues with my car bluetooth too. It works fine initially, but every couple of days I have to delete my phone and re-pair it for it to connect again.

Same here, takes me 3 or 4 times to try to bluetooth sync with ford sync system. Yesterday it would sync then play for 30 seconds and pause play back. I don't know if its the phone or lollipop as alot of the problems I see are also happening on my nexus 9.

I had Bluetooth issues on an old phone, and when I flashed different roms the issues were fixed. This leads me to believe that it's software related

Identical experience. With my S4 and my Nexus 9 I was able to literally get to the edge of my large yard before losing connection with my Vivosmart. Now I can't leave the room since getting my S6. I hope it's software and we can somehow change it, because it's ridiculously bad. I also have had to turn my BT off and back on three times this week because it would crash and refuse to talk to either my Vivosmart or my car. As soon as I toggle the BT on the phone it reconnects to everything. Seems to be triggered by starting my car (i.e. the BT car interface becomes available.) Never had either problem with the S4.

Since so many people are having this problem, it's probably phone related and not just an isolated incident.

Yeah this is one of my only remaining complaints about the device. I can't use my Vivosmart for sleep tracking anymore...it disconnects/reconnects way too many times and the persistent vibes wake me up.
So honest question...let's assume it is fixable by software tweaks. What's the fix in that scenario? Reroute more power to bluetooth radio? Other?

Well I've seen a lot of threads online for other devices where an Android update affected bluetooth range. Obviously there's some sort of software control for this. I'm rooted, and I'm willing to try some things but I don't know where to begin. I'm not an OS / Kernel guy.
i wonder if its what it is connecting to as well as a problem with S6? i have the Motorola Buds headset and it has worked as expected giving me about 100 foot range when talking on it. i also have a 2013 Ram truck with Uconnect and have not had any issues and it connects right away and reads my text etc.. as it was doing with my Note 3 and ATIV.
i havent tried other devices but have a few like a speaker and will see as i use them if i have issues.
Haven't messed with Bluetooth that much on this phone, but I think wifi is a bit weak

I've had Bluetooth issues. Seems really short range.
Wifi is about the same as my LG G2, but BT is about half as far. I used to be able to get around 15m at work (lots of shelving) but now I'm lucky to get 5m before hearing static and starting to cut out. Sucks because BT is my main source of music at work.
Anybody had better luck after applying the new ota?

Choppy Bluetooth?

Just wondering if anyone else is having issues with their bluetooth? Mine seems to be ok for a while then starts cutting in and out to the point I can't listen anymore. Seems to happen every time I use it and with three different radios. I plan on visiting the Sprint repair shop but wondered if I was missing something?
Having the same issue, I've already tried deleting the bluetooth cache, un-pairing/re-pairing and even went as far as to boot into recover and delete the entire cache.
Nothing seems to fix the issue, still cutting out like a champ. Starting to consider going back to the note 4.
Same problem here when I connect to my cars bluetooth radio. Also the network connections seem to be all over the place as well..

Give them time, they had some similar problems with the S6 Edge and got them fixed relatively quick.
Yeah I can hold the phone a certain and replicate it often ... Usually blocking the bottom right antenna spot
Same problem here. I've had similar issue with the Note 5 but it wasn't as bad as on the Note 7.
My Bluetooth reception is a lot better on my 7 than note 4.. I haven't had any choppy or cut off music with my bluebuds x. On my note 4 i would get it all the time

Mine has been VERY choppy. To the point that I dont even bother with Spotify in my vehicles anymore. And thats my main source of music!
Ditto. Ford sync system in my 2015 super duty. I thought it was my trucks problem. Par9ked my wifes s5 and no issues. Pandora is my main source.
Sent from my SM-N930P using Tapatalk
0 problems here, pairing 4 different types of headsets, 3 vehicles and even my computer and gear watch streaming the sound through either. I mainly use pandora and sometimes just the music app or youtube. My data is what seems to be very touchy on this phone, where on my n5 I still get more bars than the n7 in the same areas.
I have the same problem, so does my wife's Note 7.
I had the same problem then I went into the settings for advanced location services and turned off random bluetooth scanning and wifi scanning. Now it works perfectly.

I have no issues with Bluetooth whether it's in my car, through my wireless headphones or using my Gear 2. I'm loving this phone. The bluetooth connection is actually better on this phone than my Note 5.
Also...Nearby device scanning. I shut that off as well and it has helped. Still, I'm getting occasional dropouts, but it's tolerable.

I agree with you. It's better than having those 2 settings activated. It still sometimes has its hiccups but not as bad.

Agreed. I'm still having far too many dropouts/interruptions/skips/pauses etc.... to call it a final release. I listened to music that was on my device and still experienced the dropouts/interruptions/skips/pauses. Has anyone else experienced Pandora speeding up toward the end of a song?? Almost like the song is sped up to compensate for the delays/interruptions??
Meh...
No chop here, just got my N7 today. Tested on Klipch R10B, KMC3, Groove, UE megaboom, Lexus Infotainment and Harmon Kardon Aura, Braven BRVX
