[Q] Bluetooth 44S vs cm12 - ONE Q&A, Help & Troubleshooting

Okay so I was on the M8 for about a year being a crack flasher and never having my phone set up quite the way I like it. I then switched to this phone and am loving it except the bluetooth. When I got it, I updated to 05Q before trying to connect to my car's bluetooth. I then had a lot of problems with bluetooth connecting, It would take forever to auto connect, music would skip and my phone would randomly disconnect. I did some reading and discovered it may be an issue with the update so I used the tool kit to downgrade to 44S. While less often, the issues are still very much present. I've been tempted to try CM12 but need something relatively stable. That being said, the 11s doesn't seem to be very stable itself, and I'm curious is bluetooth is better in the cm12 nightlies. I've done some research and I see references here to issues and then fixes and I'm not sure where things have landed at this point. Looking for some input on whether things would improve if I switched to the nightlies. Forgot to mention on my M8 bluetooth in my car worked flawlessly.

Bluetooth issues

Is anyone else having problems with the bluetooth in the car? I am pretty frustrated with the performance of the bluetooth in my car (Infiniti G37xS). I used to have a Rezound and that worked pretty much flawlessly. As soon as I got in my car it would automatically connect (since I leave BT on). The Rezound also connected for both media audio and phone audio, meaning I could be streaming music but it would still be connected as a phone in case I got a call.
Now on to the SGIII...It is extremely hit or miss whether the phone connects to my car automatically (mostly miss). When it does connect, it seems to only let me connect as media audio or phone audio. If I try to check both it disconnects and won't work. So that kinda defeats the purpose of BT in a car IMO. Then the next issue, when I finally get it to connect to stream music, it disconnects quite a bit and sometimes it takes me forever to get it to reconnect. I have to switch outputs in my car, turn off/on BT on the phone, etc just to get it to reconnect.
It is VERY annoying. Does anyone else have these issues? Why is this so much different than my Rezound? Anything that I can do to alleviate any of these issues? (Other than using a cable for streaming)
I had issues with my first GS3, it would make a clicking nose so they replaced it. This one works great. My wife's car is the only one with the BT connection but when ever I use her car it works seamlessly. Sorry you are having issues. I'd talk to vzw to see if they'll replace it. Have you modified your GS3? If you're running a custom rom then I would go through vzw.
The phone is 100% stock. I really don't want to return it for a refurbished phone though if I can avoid it.

My experience with stock on 3 vehicles, one Chrysler, one Ford, and one with an aftermarket Sony head unit was no issues whatsoever. As soon as I began to run CM10, I have had nothing but issues just like you described, connect to phone and no media, etc. I also have a friend who has a stock S3 with a Nissan and has no issues with Bluetooth. I did have issues with the Nexus in a Ford, and it was rectified when there was a Sync update. If you are current with updates in the car, I might consider a swap if I were you.
Stock phone syncs with my Ford just fine. On CM10 I have to use the alternate sync method for syncing. Does Infiniti offer that option? It may help.

I get an occasional (once a week or so) disconnect and then I have to turn off the car and turn it back on to reconnect. Annoying.

My phone connects just fine to my '12 Charger, but the media info does not show up on my screen. I can fast forward, rewind, etc, but I do not get the album art and artist. Anyone have a fix for that? I have moved to PlayerPro because of the issues with the stock player on the phone, and I have enabled the avrcp support but still no avail.
Well I tried it again this morning on my way to work and it worked flawlessly. Both streaming and phone audio. The only thing different was that I installed the new update that Verizon just pushed out (kinda wish I didn't because of all of the crap they put on there, but oh well). At least my BT seems fixed now. Strange.
Thanks for the input from everyone!

[Q] Bluetooth pariring in different roms

Hi!
I have problems getting my Creative WP-350 headset to connect properly. I went away from Sense some time ago due to different problems and started using CyanogenMod. I was on 4.2 and it was good in general. Used it for a long time and now I decided to try something fresh. So i tried Venoms Sense 5.5 3.1.2 version and its a beauty. But due to random boots I dropped it and went for version 2.x. Bluetooth pairs but fails to give me "the second beep" while connecting. Resulting in the sound being sent to the phone speaker. Now i ditched it and went back to CM, but on 10.2 running android 4.3. Still the same bt problem. No second beep.
Anyone else having this issue across different roms and are there any tricks I can pull on it?

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

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.

Are you still experiencing poor Bluetooth audio in your vehicle? Mine is still the same.

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.

[Q] oneplus one bluetooth problems

i've seen this being discussed a few times but with no resolve.I bought 4 oneplus one phones altogether.The first two were for me and my daughter bought a week apart.
These have worked flawlesly and both have been rooted both connect to the bluetooth in the car with no problems.
I then ordered one for the wife and the brother (family thing going here) they both arrived at the same time and both failed to pick up any signal...
I updated them through wifi then the phone aquired a signal with no problems.But here is the problem, both of that phones will not connect to the cars bluetooth..
everything on all the phones match up from the android version to the baseband so i can't get my head around why there is a problem.?
i hear that its a problem with cm ! but why are some working and others not?
are there any roms that are not cm11 based that i can flash and see if it is the software that's causing the fault or should i wait to see if there are any updates to fix this common problem?
It's the brother's phone thats the problem,he was a long time apple user and i convinced him to change to the opo now thats jumped up and kicked me in the butt...
if this is the wrong place to post this question i do appologise,not used to posting on forums.!
thank you
bluetooth problems
well here is an update if anybody is interested.I installed multirom and mahdi rom,bluetooth connects no problem now
I'm having the exact same issue. I had a Chinese OnePlus that connected easy-breezy to both my BMW and Acura cars. I got a new OnePlus just last week which has not been able to connect/pair at all with either car. The phone can not find any BT devices.
This is back breaking here in the anti-cell phone+driving Northeast.
When they do connect, as mine does, can it send/receive text msg's and emails via the car. Mine works for phone calls and music but no msg's. 2014 Toyota Corolla
same here, just got my OPO not quite a wek ago.
64gig-version, rooted, stock FW, latest OTA.
my BT headset connects just fine, just tried it in the car today, but the phone just does not find the alpine CD-headunit (connected fine with my GNEX or N4 before).
im actually thinking about trying ParanoidAndroid-ROM wich i liked very much on my N4.
any leads?
OK then, I just flashed paranoidAndroid .. Ta-Daa: connects to in-car BT Unit.
ParanoidAndroid by the way doesnt come with the OPO-Lockscreen, but the double-tap to wake up. just enough for me.
cheers!

Which ROM doesn't have these bugs?

First, my apologies if this has been covered elsewhere but I don't read every post and XDA gets so much traffic that searching cold usually doesn't work well (and hasn't) for issues like these.
A bit of background.
I've used CM10.2, and loads of CM 11 nightlies and snapshots and have had the following issues on my One S
1) CM 10.2 crash happy. yes, I did do a factory reset and clean install. A couple of times just to make sure the problem wasn't me.
2) Went to CM11 and have the following issues consistently
1) Bluetooth crackle. usually after a fresh install things sound fine. After a few hours or a day the audio will start to crackle, almost like all the highs are clipping.
2) Bluetooth range. Much like the last one things start off ok but when the crackle appears, the range also drops to nothing. I can have the phone in my front pocket while I'm walking and experience regular signal drops and loss.
3) Audio playback through the ear speaker doesn't work except for phone calls. Everything else only works through a headset or on the back speaker.
Most everything else works well but these items are a deal-breaker. I've tried several CM11 based ROMs and Carbon and had the same problems.
Am I doomed to go back to stock? In the end I need something that works but also can get the latest security updates and Tmo has dropped this phone like a hot potato.
Try Viper.
Well, my initial attempt resulted in a phone that only boots to recovery.
Going to try to temporarily go back to CM since I need a working phone this afternoon
