Bluetooth unreliable - can't reconnect - Moto G 2015 Q&A, Help & Troubleshooting

I have the unlocked Moto G3 (2015), and I have consistently had unreliable Bluetooth connections. It affects bluetooth headphones and always connected devices like a smartwatch and fitness tracker.
Currently I am on CM13, but stock had similar trouble. The Bluetooth device will connect and work for a while and then spontaneously disconnect as some point, and be unable to reconnect. The solution is a full reboot.
Has anyone else had trouble with this?

[Q][GLITCH]BT stops working after using wireless tether

every time i use wireless tether after i have switched it off none of my bluetooth devices will connect to the phone until I reboot.....anyone else experience this?
Have not tried that yet - But I di have a Bluetooth - WiFi issue. If i try to uese Bluetooth on a WiFi call, it usually does not work right.
I had similar problems CM7 on a different device, but not with stock. Am on stock now and not happy
Bluetooth working excellent!
WiFi calling working excellent!
I will try to use wireless tethering....
5 min, please
Yes I have experienced BT connection issues. Even after a reboot. It sometimes will take 2-3 mins for my headset to connect.
No issues here

No issues here either. I was actually just saying to myself this phone has one of the best Bluetooth implementations I've ever seen so far. I've used with BlueAnt S4 car speakerphone and my car's A2DP audio bridge simultaneously as well with other devices by themselves such as a Bose BT1 headset, a Motorola DC800 A2DP audio bridge, and various Broadcom based adapters in computers... no issues at all (which really surprises me). I've used WiFi tethering extensively and leave Bluetooth enabled and never have any issues when I go to connect.

ANT+ support wanted

Hi folks
do we have any ANT+ people who would be willing to help me troubleshoot my ANT+ issues on my Xperia Z1?
No-one on the Z1 forum seems interested in ANT+ - which is understandable as it is slightly niche
Sony Xperia Z1 with rooted stock (android 4.3) (and ANT+ radio and ANT+ service) installed.
Garmin soft strap HRM.
I find that when I start ANT+ in an app (e.g. oruxmaps, ipsensor man etc) sometimes it connects to my HRM without any issue, but then crashes later or sometimes it doesn't connect at all.
I also find that if it has connected but then I stop ANT+ in the app and then start again, it never re-connects to my HRM.
A temporary fix in both cases is to stop ANT+ via the app, toggle off bluetooth in phone settings and then start ANT+ again in the app. Works temporarily 100% of the time, but after a minute or two the ANT+ connection drops again.
When I am experiencing the issue connecting to the HRM, if I have toggled on the Developer Option "Show all ANRs", I am getting ANRs from the ANT radio service.
When I am experiencing the issue connecting to the HRM, if I do not stop ANT+ in the app and toggle off bluetooth in phone settings, bluetooth is restarted. I cannot understand why bluetooth is seemingly being activated by ANT+/apps.
I have tested the phone in isolation and in parallel with my PC monitoring application (Golden Cheetah). The PC is rock solid i.e. the PC connection to the HRM is not dropping out when the phone loses the connection to the HRM.
What can I do to troubleshoot this issue?
I already replaced the HRM battery last night, and have gone through multiple times unistalling apps, blowing away app settings etc etc.
thanks

Bluetooth Issue

Hi Folks,
Anyone had any similar problems? When my Z5 is connected to my VW Golf it constantly disconnects and reconnects, tried rebooting the phone, un-pairing and re-pairing still no joy
Just wondered if it was a bug sony needed to be aware, it's as if it's a power save feature that turns it off and on?
Cheers in advance.
Mine stays connected to my van fine
I use one of these in my car -> http://www.amazon.com/SoundBot-Bluetooth-Hands-Free-Wireless-Streaming/dp/B00RH29CJO
No problem so far, it stays connected
I´we got the same problem with my Z5 and Pebble Time
I also have bluetooth streaming issues. Connections initiated by the phone seem to work fine. Those initiated by the car do not. Have zero issues with a Nexus 5. I believe the issue may be related to the "Throw" service.
My Z5 only connects to my Nissan Qashqai 50% of the time. My previous HTC M8 would connect every single time, but Z5 has to have bluetooth turned on/off to work with the car. It's incredibly annoying and I hope it can be improved with software
Sony will probably have to fix it in next update...
I have the same issue with a garmin watch but only since the update I had yesterday, same with the car stereo again since yesterday

Tried disabling the "throw" function and it's still doing the same.... really annoying !!!
Hope Sony are reading...
My Bluetooth keeps my device awake, which renders my Android Wear kinda useless

I have a 2014 mini and the Bluetooth doesn't have any connectivity issues, but I definitely have bugs with music skipping, especially if I have maps open or something. Better than the initial 5.0 Bluetooth bugs but still really annoying. Probably my main gripe with this phone so far other than the fingerprint scanner
I have exactly the same issue as the OP with my garmin watch it connects then disconnects every 5min or so, whats weird is if i unpair and repair the connection is good for about 3hrs then starts playing up...
I also have a nexus 6 which i've tested with lollipop 5.1.1 and marshmallow and it works perfectly, my HTC M8 i used to have did exactly the same issue's as this sony, its got something to do with the trusted device settings i think the nexus doesn't ever ask about trusted devices both the HTC and this Sony do so it can't be just coincidence...
Is there anyway to disable the trusted setup on the device ? Garmin are saying to connect via there garmin connect app and don't actually connect with the phones bluetooth directly, i've tried that still doesn't work properly... frustrating...
I also have the same problem in my BMW.
Additionally, when I start call using built-in handsfree it suddenly switches to the phone's speaker then after 10 second back to handsfree.
Hope Sony fix this soon.
Does anyone know if its possible to install a apk or whatever it needs to be so that you get rid of whatever modifications sony have done to the bluetooth process the only reason i ask is i know through my nexus 6 that the bluetooth works perfect from google so replacing the Sony setup with the pure google setup should cure the bluetooth issue's or if there is anyway to disable the trusted devices issue that i'm sure is causing my bluetooth problems this is annoying me enough to consider getting rid of this phone... Excuse me ignorance i'm not clever enough to understand if this is an impossible task...
Don't know if this will work for others but last night i unpaired everything bluetooth on my phone switched the bluetooth off restarted my phone switched the bluetooth on and re-paired and now the 2 things i had issue with are working flawlessly since about 6pm last night... ???

Similar issue with pebble time, every so often it disconnects. My only doubt is which of the two is failing the pebble or the phone.
No problem with car in-calls or audio bluetooth.
I have a Z5 and I have pretty much the same issue with a 2010 Jag XF, phone connects via BT for a differing period of time then disconnects, sometimes reconnecting sometime not.
I've not had this happen during a call, and not with other Sony Xperia Z's I've owned.
Also I don't appear to have this with other items connected Via BT.
'I aslo have problems with the BT. The z5 will pair with my garmin edge 520, after that it can't find it no more and can't connect.
With my Stereo amplifyer, NAD D3020 it can connect as it does not require pairing but the connection is poor and i get alot of artifacts when i play music over it.
For the Edge 520 it stops everytime it ask for Trusted device.
My phone is in for warrenty repair, Was for a cracked rear glass, but i told them about the problems with the BT too. The phone is on it's way back now. Hope this will fix the issue. If the BT don't work, the Z5 won't be usefull for what i want to do with it.
I know with my garmin, garmin told me not to connect with the phone directly just the connect app, weirdly my watch has been working perfect for about 3 days and now this afternoon is playing up again I've installed nothing new or changed any settings baffling
Sent from my Sony Z5 ooossshhhh
Similar problem here with my Android Wear and my Cartio Strip. Continuosly disconnect, B icon on status bar disappear, then re-appear after 1 - 2 min.
Someone known how to disable throw?
Thanks

Is the V10 also experiencing bluetooth problems?

Is anyone else here having a problem where bluetooth switches to loudspeaker when playing music?
I want to find out if this a general EMUI 8 Android 8 problem or if it is specific to the Mate 10/Pro.
For more details, here is the original issue thread for the Mate 10 Pro:

No Problems,Bluetooth works with headphones as long as you hear
Yes, there is such problem.
Wifi and connectivity speed drops even when Bluetooth module is on, without any devices connected, and becomes hardly usable.
Thus if you intend to use any Bluetooth devices together with WiFi, this is hardly a device for you. This is especially the case if you intend to use any of the smart watches of fitness trackers, that become hardly usable due to the repeated disconnections.
I don't know if this is a EMUI related problem, or not (installing Lineage may void my warranty, and i intend to return the phone), but the problem is quite persistent.

I was looking for some answers to my problem and I think this could be related... As you mentioned, when I have bluetooth connected to my earphones, the wifi connection speed drops a lot. It depends on the router though... I have a Virgin SuperHub 2 (UK) and it drops to 4-10 Mbit/s or so... I have done some test at work with a Netgear 6800 and it something like:
No bluetooth: 90 Mbit/s down / 90 Mbit/s up
Bluetooth connected to earphones but not playing anything: 67 Mbit/s / 90 Mbit/s
Bluetooth connected and reproducing music: 27 Mbit/s / 80 Mbit/s
Just checking the speed tests on my phone with the superHub 2 at home, it drops to 7 Mbit/s if it's connected to bluetooth and at around 100 Mbit/s if it's not...
Is there any software fix for this problem or is it a hardware problem?
Thanks!
I've ended up returning the phone, as I use a pebble watch and a fitbit m the time, and a headset in the gym, and then WiFi became intolerable.
I really liked this phone, but after 10 days of looking for a solution I've ended up returning it.
bluetooth phone calls not working
The problem is bluetooth audio for phone calls isnt working, i tested this
in 3-4 vehicles as initially thought this could be problem in the vehicle.
However i noticed the same issue in all vehicles. So this is definitely not
a vehicle issue. the phone audio on calls isnt routed via the vehicles (pairing is fine) -
however if play a song through a music player on phone, it works fine.
i have tried restarting phone several times and also deleted all pairing
and re-pairing the devices, i deleted the bluetooth data/cache as well but
no success..
Anybody have this issue on the honor view 10 ?

I further tried resetting the network settings, still same problem, hi care diagnostics tell me bluetooth is fine..strange!
I am on B160 and no Problems with Bluetooth or Wifi at same time enabled.I test on 2 Vehicles calls works and play Music with the View 10.I test with Youtube over Wifi with Bose Headset over Bluetooth,all working without any Problem!
Hm, I use BLK-L09 and I didn't notice either of those problems. Bluetooth calls work beautifully with my car's built-in bluetooth thingie and I can use WiFi with no problems while using my Mi Band 3. I use Carbon ROM though
I'm on a BKL-L04. I have not experienced any issue at all with bluetooth. I have an LG Urbane connected all the time. I stream music in home and in my vehicle and bluetooth has never caused me any issue - even with wifi on (and wifi does not slow, at least to my perception). Times when I've used my bluetooth headset, I still haven't had any bluetooth issues. (I came from, and still own, an Honor 8. I could barely leave the room with my headset connected to the Honor 8 before the signal would start dropping. No such problem with the View10. In fact, I have much more range in my house on my headset on the View10 than I did on the 8). My View10 is completely stock, no root.

Hi my problem with bluetooth started all of the sudden , it was working fine all the while - it isnt anything to do with using with wifi.
The problem simply put is bluetooth pairing and song streaming works fine, but through bluetooth phone calls audio isnt working - very strange!

Bluetooth issue in car: Stock ROM vs non-stock ROM

Hi all,
I have a 2008 vehicle in which Bluetooth seems to be a problem depending on which ROM I have installed on the device.
I'm currently on Android 9 OB 7 and Bluetooth connects and stays connected through incoming and outgoing calls. Works flawlessly.
However, with for example Lineage (among others), the Bluetooth pairs, but connection drops soon after or drops after the first call with the car stereo showing "Net Search", meaning the car BT lost service but the phone Bluetooth is still connected. I've tried restarting and resetting network settings but no luck at all. Changing dev options doesn't work either.
I'm thinking it could be a Bluetooth stack difference?
Is there a way to replace the lineage Bluetooth with OOS?
There is no bluetooth.default.so file that I could find
Any help or direction is appreciated.

I am having the same issue with 9.0.2 OOS. So not sure if this us a compatibility issue with more than 1-2 years old vehicles or something else? Glad to hear that OB7 is working fine for you. Hope fix is coming soon. It's simply annoying.
I am having car connection issues as well. I have a 2010 Ford Edge. Just moved from Sony Xperia XA1 Ultra on Orea to my first OP device - OP6 Pie 9.0.2 - I can connect to my car initially but once I turn off my car, I have to go through a series of reconnect steps. I called tech support and we spent about 45 min troubleshooting - of course I was told I was the only one who had complained of this issue - anyway no resolution. The only way I can "reconnect" is to go into my car's system settings and select "connect to BT device" then toggle bluetooth off and on in the phone - sometimes this works with the first go, other times I have to repeat this cycle 5 or 6 times. Simply selecting "previously paired devices" in the phone app doesn't work either.
Really a pain in the tush, because I am usually in a hurry and don't have time to go through all this scenario to get a connection.
On the other hand, I have a bluetooth ear piece (made by Samsung that is like 5 or 6 years old) that reconnects every time I turn it on, no problems.
Car connections too but was not present in omni
I found for stock, performing a network reset (mobile, wifi Bluetooth) then restarting the device fixed the Bluetooth connection issue.
For custom non-stock ROMs, for my issue at least, I found its not a Bluetooth issue at all but rather the mobile network drops and the car Bluetooth cannot reconnect. The same network reset as above does not work but what does work is toggle off the "automatically select network" and manually select the mobile network from the menu that pops up. This keeps the mobile network intact (until the next device reboot, at which point repeat the steps) with the car and all is good.
I only figured it out by accident; hope this helps others.
