Bluetooth suddenly disabled.. need reboot to enable. Once a day - Nexus 5 Q&A, Help & Troubleshooting

Hi there,
I have a Nexus 5 with CM12.1-20150801.Nightly-hammerhead and a 3.4.0-ElementalX-N5-4.04 Kernel.
I have bluetooth enabled for my Pebble Time and my MiBand and for the car handsfree.
When I freshly boot the rom the connections work fine.
Once of a sudden my Pebble says no bt connection.
And the Icon on the nexus is gone.
Bluetooth is disabled.
Trying to enable BT wont work. Sometimes Settings crashes while trying.
Then I need to reboot to make it work again.
Right now I have to reboot at least once or twice a day....
Andy ideas?
How can I find out what causes the BT to disable?
Thanks
regards
Chris

Bluetooth turns off randomly

Hi,
I am using my HTC Touch Pro with an Opel Vectra built-in bluetooth carkit.
All functions, like browsing the address book and call registers, are working fine. However, at random times, my carkit reports no phone. When I then check my Touch Pro's bluetooth status, I see that it is has been disabled.
After manually re-enabling it, I can pair with my carkit for as long as it takes for bluetooth to turn itselves off again.
I've already tested with JETware, but that does not change anything. Also tried the universal broadcom bluetooth stack, but doesn't seem to work on the Touch Pro. HTC only comes with a standard answer that they don't support all carkits and headsets... Since the BT stack on the phone seems to crash, I don't think it's a carkit issue.
Anyone here with the same issue? And maybe a solution?
Thanks and regards!!
Start -> Settings -> Connections -> Bluetooth -> Timeout (tab). Turn off Visible mode set to "Never".
I think this must be your problem.
Hi Freco,
Thanks for your reply! This option is set. However it's not really the visibility that turns to invisible, but the whole bluetooth stack is being turned off completely. Need to fully re-enable it via Comm Manager.
Any other options? Does anyone know if there is a working broadcomm stack for the Touch Pro?
Regards!
Hi,
I have exactly the same problem with a Vauxhall kit, I have tried all sorts of things, but nothing seems to work
try:
start -> settings -> connections -> bluetooth
timeout tab
select 'never' from drop down box
Hi Brendo,
Unfortunately this doesn't solve the issue. Once paired, the connection even works without being visible. It's also not a fixed period of time before the disconnect takes place (can be within a minute, sometimes after half an hour). However, the whole bluetooth icons disappears from the top icon bar and comm manager shows it's turned off completely.
Hope somebody has any other ideas, because the only thing HTC can do is point to the carkit vendor :-(. Since all functionality is there when connected and the phone is turning off BT in some way, I really don't think this is caused by the carkit vendor. I should at least expect BT to stay enabled on the phone.
Thanks!
Yes, same here, BTW I have tried this in my Friends Saab, and the same problem.
same problem here with a Opel DVD90 buildin bluetooth carkit.
With other htc phones it always worked like a charm, but my mda vario IV continuously disconnects after a random time period and shuts down the complete stack.
Try this!
I have the same problem with my opel with original bluetooth-kit (2007). On the touch pro I changed the band and network from auto to GSM, as G3 reseption in this area is quit poor, especialy while driving. It helped for me, at least the last few days. I agree this has been an annoying problem.
I have tried to switch to "GSM only mode" in the past, but as far as I remember it does not completely solve the issue. However, I will give it another shot! Actually I can't figure out at what point it occurs... It can happen within a minute or after half an hour without using any funtion.
Does one of you know if there is a way to do some debugging on the Bluetooth stack?
And has anyone experience with other Windows Mobile 6.1 based phones in this combination (just curious if it's a WM issue or HTC only)?
Furthermore I did some tests with JetWare. You should be able to limit the number of synchronised items then (might be related to this issue). However, it looks like this configured limit is being totally ignored: when I limit my recent call list to 5 with JetWare, it still syncs about 25 items. Anyone tested with Jetware?
I have tried the GSM only mode, this didn't help either
I have now given up and got myself a Nokia E66, which works perfectly.
All contacts are pushed to car, no disconnects and AD2P works so my mp3 ringtones play through the car speakers! Sweet
Word of note, I had issues with N-Series phones, would connect ok, but contacts would not push.
I have the samen problem with my HTC Touch Pro and Saab.
bluetooth pairs just fine with my pioneer bluetooth enabled deck, but the problem iwth mine is once i receive a call sometimes no sound comes from the car, instead the earpiece is still on. but if i initiate the call first sound works just fine and earpiece on the phone is disabled, BUT once the call is ended bluetooth disconnects randomly and the phone takes a good 1-2min to reconnect. i absolutely hate the bluetooth on this phone!

I am having the same problems you describe. Anyone got an suggestions???
I encountered the same problem; first with an opel udp carkit and next with the bluetooth interface software from homeseer.
It has something to do with phone signal loss.
With the opel carkit I noticed bluetooth automatically turns off when the phonesignal switched from 3g to gsm.
I also noticed that in my home, BT turns off whenever I have been in a room with no phone-signal reception.
try this thread, both registry change and attached cab file, reset. DOn't worry if the make visible to all option is unchecked.

Keep Losing Bluetooth Pairings

Anyone else seeing some odd behavior with bluetooth pairings? I keep on having to re-pair with my laptop (Win 7 64x) and my car (Audi S4). Complete pain.
I use it with my computer (Win 7 32-bit) and my Motorola bluetooth headset, no problems since I first paired each (sometime in July).
I have the same issue at times....quite frustrating and I have found no way to stop it from happening....
Yep. I get this too. My only fix has been to turn off my plantronics earpiece and when turned back on it connects.

I am JH3 as well, FWIW. Dunno if JF6 gave me the same problem. I now have 3 of the same device in my Win7 BT folder. I also remember seeing the BT settings reverting to old ones.
Problem I keep on having is that the media profile, or A2DP, setting won't enable when I turn on my stereo bluetooth headset. It'll sometimes reestablish the media profile if I keep on turning off and on the bluetooth setting on the phone and headset, but most of the time I just end up having to re-pair my it. Would be awesome to know if anyone knew how to fix this.

I suppose I should just throw in there...I never had the problem with JF6. I'm running JH7 now and still have not experienced it, will report if I notice anything.
More Info
While I don't have a solution, I have researched this problem a bit.
In my experience the problem happens when I disable the phone capability of a device.
For instance, I have a pair of stereo bluetooth headphones that I can make calls with, as well as listen to music and other audio.
If I edit the profile and disable the phone function, the whole device disappears from my phone if I reboot it. If I leave the phone option enabled, it does not disappear.
Disabling the media option does not appear to have any affect as long as the phone option remains active.
My rom is stock.
The pairings don't disappear, but my motorrokr s9-hd disconnects and I have to restart the player and then press the headsets connect button. Just hitting the connect button only activates the display, but doesn't start the player. The way the headset connects just isn't right.
There are things like the headset disconnects and the browser crashing, that sometimes don't happen for days and then will happen repeatedly in minutes.
I do hope that froyo fixes some of these problems...
I have some similar problems. I have a Spracht AURA Mobile BT Speakerphone in my car and I don't use it that often but when I turn it on it doesn't seem to keep the pairing every time. It worked fine with my TouchPro on WinMo.
Another strange thing is that when it is working and I turn off the BT on the phone then come back in the car and turn it on again and it pairs, it immediately starts redialing the last number I called. VERY annoying. Fortunately I've caught it every time but I don't know why it would do that.

[Q] bluetooth ???

I was looking for this on all forum and did not find answer. I get second one skyrocket and second blutooth device plantronic voyager pro HD and still have problem as is had with last one. Devices paired with no problem and worked for some one-two days with no problem. After that time sound is scrachy and disconnect from phone, then i can not turn on or off blutooth on phone and also can not find device antill i restart phone. Skayrocket running on rooted stock and I installed CWM on. Did not flash with any rom yet. Any idea what is the problem or this is hardware problem again ( that why i replace last one phone and bluetooth) ???
There's an issue with bluetooth on the skyrocket and the galaxy s2 for some reason. I am running the newest version of seanzscreams ROM and I've had no issues since I updated. My bluetooth would think it was connected but when I made a call I'll have no audio. I would have to reboot my skyrocket and resync my bluetooth. Hopefully they fix it in the ICS release.
so many ppl having bluetooth issue. SO i ma gonna take out my jawbone and see if i can help these ppl out.
I have the Era, Plantronics backbeat 903+, and the Blue Ant Q2 and they all do the same darn thing. It's weird, the phone even shows it's connected. When I press the button on my Era is says how much talk time is left but not connect me to your phone. It is a pain. I wish it would automatically sync to my car when I turn it on and switch off my earpiece. Guess we need to wait for an app or something.
Well my jawbone got connected to phone easily. Made phone call and every thing went smooth so good news for me. Running Ice cream rom.
What I found was that you have to make sure it's set to auto connect if not then you'll have to manually connect it every time in your Bluetooth settings.

Thanks all for answers.. I hope someone will find solution for problem , i also will try to flash some roms to see what is working what not..
I was having a strange problem with bluetooth as well. The audio would become undecipherable sometimes. I found that when I had wifi turned on I could recreate the issue and when I turned it off the issue when away. I've since used tasker to turn off the wifi when initiating a bluetooth connection and haven't had the problem since. Your results may vary, but couldn't hurt to try it out. Hopefully it'll fix your issue.
There is a definitely issue with bluetooth. I use 5 different sets of bluetooth (Bose, Plantronics Voyager Pro, Plantroinics 975, Blueant Q2, Jawbone) and they all seem to have an issue with Skyrocket. Even tho they are paired and connected to the phone, I can't seem to hear anything. Also, sometimes it does not turn on or off. There are times when it won't even connect/pair even though the bluetooth is set on auto connect. I have to reboot in order to get it working correctly. With my Bionic, I never have that issue. This is my 2nd set of Skyrocket and my first one had the same issues.

In "Settings", "Use Power saving mode", there are a number of defaults, one of which is "turn off blutetooth".
If you have powersavings enabled and this ticked off it will drop your BT connection if it's idle for a bit... It also has the same foy wi-fi, gps, and sync, and timeout and response values for brightness and timeout.
Also note that reaching your "low power" threshold set in this area will turn off all of those too.

I did try everything you sugested and only think so fare working is when i flash with icescreemsandwich rom.. so if anybody have same issue can try this.. thanks all one more
I'm on my second White Skyrocket and am still having the same bluetooth issue. After connecting with my car, then leaving the car and returning later, I cannot turn BT back on without a reboot. Once it connects, it works well though.
Issue w/Speaker
I've not connected with a bluetooth headset, but I have HORRIBLE audio issues when using my Parrot 2.1 b'tooth speaker.
Rocket connects & keeps connection, but audio drops & is choppy - even when < 4' away.
White Skyrocket on faux's kernel & seanscreamz SkyIceCreamSandwich RC6.6 ROM.
I did something diffriend on my wifes skayrocket with stock rom and no root totaly clean...
I turn on bloototh on phone and connect to handset, connection is exelent so i never turn off bluetooth on phone and so fare so good for last 2 days.

BT sucks down too much battery life to leave on all the time for me.
That's what we have found to be the issue....everything works unless bt is toggled off then back on
Bt draining battery when not connected does not make much sense...it doesn't scan frequently once on from what I can tell. Would have to run some logs to verify

Try with Wifi turned off and see if that helps
I'm running Sky Ice Cream Snadwich 6.5Z. I seem to have bluetooth issues with my Backbeat 903+ when Wifi is turned on. I just tested it. I hung up the call, turned off Wifi and the audio was much better. I still have to have the in-call volume turned way down though
I will say that the 903+ were kind of crappy when I used them with my iPhone 3GS too though. Again, had to turn the volume all the way down. Its too bad because I really loved the first gen of this headset
I was palying with bluetooth and I notice if i turn off Bluetooth PBAP and Bluetooth Share my connection to handset if perfect. Can somebody explain what are this two thinks and what role they have in phone ?
You can find Bluetooth info here:
(sorry new member... can't post outside links... search wikipedia for "Bluetooth profile")
It will explain what PBAP and all those other services that do not work and cause you grief...
I have a feeling that this issue with this model of phone could be because it is using Bluetooth 3.0, maybe the Bluetooth devices we are trying to connect to are not compatible or struggle with the data transfer rate?
In any case it is super annoying, lets hope the issue gets fixed with ICS. I am trying to use my SGS2 LTE (on Rogers in Canada) with my Bluetooth in my Hyundai Tucson 2010... it rarely connects, and when it does either it cannot download my address book or people cannot hear me.
I read in this thread "set it to connect automatically", I cannot find this setting on the phone, any help?
Thanks,

Bluetooth Not Reconnecting!!

Hey there, just wondering if anyone has a solution to a bluetooth auto connect issue. My problem is that no matter what bluetooth device I connect my phone to, it will work fine until I turn bluetooth off on the phone. When I turn bluetooth back on it will try to reconnect, but just hangs there.
For example, I pair my phone to my car, listen to music no problem, then when I get home I turn bluetooth off to save battery. Then if I get back into my car later and switch bluetooth on, it refuses to auto connect, even though the car bluetooth is still listed as a paired device on the phone. This also happens with my bluetooth headphones! It won't even connect if I manually try in the bluetooth settings page, I have to manually unpair and repair again and the process starts all over again.
I'm using DoomLords Stock 4.3 on an XperiaT. Anybody got any ideas??

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.
