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??

My phone was connected to bluetooth receiver in my car and while playing an audio book suddenly stopped. After that I've not been able to turn it back on, it attempts to and fails. I have not installed any apps recently and am still on 4.1.1 so I wouldn't think it is a software issue . The only fix i tried was to pull the batter and restart.
I'm hesitant to upgrade because other than this issue it's working fine. Does anyone know of ways to rule out hardware issues?
Thank you.
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
Hi
I am using a PX5 system and have an OBD2 elm227 (tried 2 different brands, 1x icarly and a white label product) and a iphone 7 paired.
The iphone BT works, i can call etc and in my BT settings menu all the devices are listed as paired etc..
Problem:
When i start Torque Pro and i want to choose the BT adaptor there is nothing shown...
According to Torque there is NO BT adaptor paired at all which i can choose from.
I use the latest offcial (paid) PRO version of Torque!
I rebooted the device already but this had no effect.
Is there a fix for this?
I am using malaysk rom on my PX5 device, so it is rooted and has xposed installed.
Who can help/advise
[update]
It worked after a reboot but it seems BT does not work after ACC off/on, only on a reboot or cold start.
Hi there, i also use OBD2 with torque and works like a charm!
Try to delete all the BT paired connections first and after that, pair first the OBD2 adapter and test it!
Regards.
1. Press reset button
2. Unpair
3. Start the phone app and pair from there
Go to torque app and select the obd
it seems when my system goes standby (acc off) the BT connection is lost after power on.
All paired devices are simply not working anymore...
Sometimes they aren's even visable anymore in BT menu after ACC off/on, on a cold start or system reboot they work again.
Is there a way that when the system goes to sleep (acc) these apps keep running in background or are restarted when ACC is turned on again (not cold start/boot).
Also other apps are killed and not started anymore on resume.
Also i cannot find any option too change the ACC time, in an other rom i could set this time for example to 10 seconds and if then returned on it would cold start.
On PX5 Malaysk rom i cannot find any menu for changing ACC sleep/shutdown time

Search the thread for the no-kill mtcmanager.apk
This will keep all apps on resume
To be able to see they menu for shut down delay you have to be on an mcu higher than 2.48 I think.
I'm having a similar problem. Iphone via bluetooth and torque worked perfect until yesterday.
Now, Iphone is not on the paired devices, nor I can pair with it again. And torque sees the obd adapter, but can´t talk to ecu and I dont see the obd under bluetooth devices .
What shoud I do?

unfortunately I have the same issue - BT works till next power on of the radio...then only after reboot but I can not connect the paired devices...
I think, it wasn't so in original ROM...
I am using malaysk rom on my PX5 device too.
Ok I was able to get Bluetooth back full time by reinstalling maylaysk rom. Does anyone have a copy of the original torque that came with the factory rom? I have the paid version but I'm having issues with it
Same here hoping for original version of torque that came with px3 device.

The torque app that came with the unit and torque pro did the same thing for me as soon as I went from MCU 2.75 to 2.8 for my HA MTCD unit.
See this thread for the torque app you need... It's at the bottom of post 1.

I just posted in Dasaita and Hal9k_ threads regarding my BT OBD.
1. Connecting but not recognized by apps
2. Not connecting to MCU anymore.
Both have been resolved with...
1. Update to latest MCU (my HA is 2.83).
2. Install/update rom to latest Dasaita or Hal9k_ rom.
3. Do a Factory Reset
4. Connect to BT OBD
5. EVERYTHING WORKS FLAWLESSLY NOW FOR ME.

For all those wondering about the connection problems - I have spent the last week trying everything - then randomly saw a video on connecting one of these devices. Stock setting for the bluetooth is password 0000 - it showed changing the password under bluetooth settings to 1234 which is the stock setting for all OBD2 devices. I went into settings - deleted all bluetooth devices - changed the password to 1234 - searched - found the OBD2 sensor (BLUEDRIVER) and it instantly connected and showed in paired devices. Fired up BlueDriver App and BAM! shes working without a hitch - fired up Torque Pro Lite and bam - connected without a hitch - for others with ELM you need to download the App for ELM because it only works with certain devices. After all the work I did trying to get it to work it was really just one little issue with the handshake *being the password* since you cant enter the password from the Bluetooth device like you would from your phone. Setting them both to the same solved the issue.

After quoting a a large post with meaningless correlations, I found postive shockra!
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.
