[Q] Bluetooth Issues

Does anyone have problems connecting their Desire S to Bluetooth devices?
My phone seems to pair to my Bluetooth hands free kit but no connection actually happens. The same situation for another Bluetooth kit i have and also my laptop!
I just upgraded from a normal Desire and it worked perfectly with all the devices.
I tried changing the radio and also upgraded the Rom from 1.28.401.1_Radio_20.28b.30.080 5U_38.03.02.11
to
1.47.401.4_Radio_20.28I.30.085 AU_3805.06.02.03
I have searched for solutions but have not found any on XDA

Might be that your bluetooth device is in a black list need to check, can yo utell what bluetooth device you have exactly?

My main Bluetooth device is a Merlin Car Mirror Kit V2.
When connected and properly paired it should 'beep' twice, but now it just connects and the phone says its paired. When you make a call it shows it is dialling but no sound comes through both ways.

Solved: ICS Bluetooth Auto-connect issue for Phone profile

Solved - Finally following setup works for me
No ICS Roms worked for me, but following ROM is working perfectly. I have tried for a day and no issue. As soon as I start my car bluetooth connected and BOTH Phone and Media Profiles remain connected. Audio Track information displays perfectly!!
XDA Thread: http://forum.xda-developers.com/showthread.php?t=1621679
ROM: Skyrocket CM9 RC 2: cm-9.0.0-RC2-skyrocket.zip
Radio: Radio for AT&T and Rogers: Radio_RIL__I727UCLE2.zip
Bluetooth Device: Car Honda CRV 2012
Background:
1) I have two bluetooth devices that I use with my phone. Blueant Q2 bluetooth headset and Bluetooth enabled car audio system in Honda CRV (factory not after market)
Note: This works fine in all GB ROMS
Behavior
1) Bluetooth is different in GB and ICS. Go to Settings => Bluetooth and look at Paired Devices.
- In ICS you will see a Settings wheel next to Device Name. Click on that and you can see "Phone" and "Media" Profiles.
- GB does not have these profiles separate.
See attached image for the state of Phone and Media profiles after I start my car.
2) Bluetooth "Phone" Profile does not auto-connect. "Media" Profile auto connects and works fine. I need to go to Bluetooth => Settings => Click on wheel next to Device Name => Check the checkbox next to "Phone" profile everytime to connect the phone and send-recieve calls using Bluetooth.
3) Steps to duplicate the issue
I see bluetooth icon seeing it connect
Few seconds later I see message "Samsung SGS ..... has been disconnected"
At this time "Media" is connected and "Phone" profile is not. In Honda it shows that Phone is disconnected (even though "Media" is connected and Music plays fine
Finally If I try to connect to Phone via Honda it always fails. But if I open Bluetooth settings and select "Phone" profile it connects and remains connected.
More Information
My guess it that in GB there were no separate "Phone" and "Media" profiles. Phone would just connect to car or headset via BT and stay connected. With ICS the phone is initiating two processes. First Phone profile connects and within few seconds when Media profiles tries to connect. This somehow throws off my Car and my BlueAnt Q2 BT and it drop the BT Phone profile connection

Bluetooth
New public methods fetchUuidsWithSdp() and getUuids() let apps determine the features (UUIDs) supported by a remote device. In the case of fetchUuidsWithSdp(), the system performs a service discovery on the remote device to get the UUIDs supported, then broadcasts the result in an ACTION_UUID intent.

I have the EXACT same issues with my 2012 Honda CRV (Non nav). (well, I’m working on this on behalf of a friend, so their car)I hooked it up to another my car with a Pioneer Avic X920bt head unit, and it was doing the same thing. I then did a firmware upgrade and initialization through KIES and now my Avic loads up, but the Honda is doing the same thing still. Although, before I did the wipe the Honda would disconnect and reconnect randomly and it would take forever for the phone profile to connect and it looked like the bluetooth would turn on and off and “freak out”. So far it seems stable, but I have yet to have much time with it.

I have a Galaxy Nexus with 4.0.4 that worked perfectly fine. Both profiles reconnect upon turning a car on and off. I wonder if Honda is detecting the kind of phone and sending the way to connect based on that and not by what OS version it is. Just a complete guess. Also, I tried with a T mobile Galaxy S II and the same thing occurs on it's ICS update.

Thanks. Do you mean to say that everything works with T mobile Galaxy S II or you see same issue I am experiencing with it?
Here is what I see with Honda after I sit in the car and turn on the car.
I see bluetooth icon seeing it connect
Few seconds later I see message "Samsung SGS ..... has been disconnected"
At this time "Media" is connected and "Phone" profile is not. In Honda it shows that Phone is disconnected (even though "Media" is connected and Music plays fine

Sorry, T-mobile Galaxy S II does same thing as the Skyrocket. Yup, same thing..honda says connection failed when trying to connect through the car. I sent Honda an email and all I got was a generic responce about turning your wifi off and repairing.

Same behavior with Infiniti G37S
I have the same behavior of my AT&T Skyrocket with SKY-ICS 4.2F6-2.1 and 2011 Infiniti G37S. It is driving me nuts that I have to manually reconnect Bluetooth every time. Furthermore, it tends to disconnect Bluetooth randomly and I have to reconnect it again.

It would be great if one of the dev can find a way to install GB Bluetooth files on ICS. GB worked perfectly for me.

A Google search shows a lot of people have the exact same problem. It might be safe to say that this is a known problem and hopefully it will be resolved soon..

I have more confidence in our dev's fixing this or finding a work around. It might be as easy as replacing ICS BT libraries with GB ones. However I am unable to get their attention.

I have the same issue but with a Dice Mediabridge installed in my BMW. Works for about 10 min then drops, will reconnect with a reboot. My Jawbone Icon stays connected and works fine, but that just had a recent firmware update. I hope this is resolved soon.

Finally a ICS Rom that works for me - see OP

So, what is so different in that ROM? How can the 'fix' from that ROM be applied onto other ROMs?

CM9 is pure google. No junk from AT&T

Works on CM9
It works perfectly on CM9 builds - I'd hope other ROMs can be modified as well...

BUMP: Still have issue
The last poster says issue comes back even running ROM. I have been dealing with this most annoying issue and still have it. I noticed when i uninstall Pandora app, its goes away. Seems to be a bug in the bluetooth stack and Pandora. Were you guys running Pandora at the time? Seems weird this thread just died with no resolution. Anybody care to explain to me what the fix is if any? does this problem follow the Galaxy S4? I am using an LG HBS-700 earpiece but it did the same thing on my Plantronics. is there a Jellybean available for this version? if so, ATT has not released it for over the air. Thanks.

Its not ota you have to use kies software and his thread is almost a year old

Thanks for your suggestion, it was actually helpful but as far as the comment about the age of thread.. if someone is suffering from the exact problem i dont think it matters much.
So, I wanted to let anyone else struggling with this bluetooth issue what worked for me. I downloaded and installed Samsung KIES software on my PC as suggested above, performed a full backup of phone and made sure it was fully charged. Now, there will be an upgrade to JellyBean from within KIES. UPGRADE! after upgrade perform a restore and most all your stuff comes back.
** A few of my games/apps installed on my SD Card kept uninstalling itself. this is a bug in JB. Go to Settings, APPS, and move the app to your phone memory and that fixes it. **
Other than that, i have been running the update for a couple of weeks without all the annoying bluetooth issues and its like having a new phone!!! LOVE THE UPDATE.
Only issue is i have more battery drain than before. i have read that installing Jellybean clean install fixed that but will have to research how to do that. Good luck.. hope this helps someone else.
P.S. this is update is NOT available over the air, so dont look for it from your phone. only the KIES software gets you this update.

[Q] bluetooth pairing issue, how to solve?

Hello, so i bougth this great phone, but bluetooth pairing(+autoconnect) is not working at all.
So to the proplem. My opo IS paired with my alpine car stereo, but everytime i go to my car opo asks IF i want to pair it...and obviously it should just connect automatically since i have paired it earlier but no.
Is this some known issue with opo or my device just making me headtache?
IF anyone have had same proplems i would love to hear how you managed to fix it.
PS. All my old phones automatically connected to car stereo after pairing once, so its most definatly opo issue and not the alpine stereo.

Okey, i got this solved by doing 2 things, but because im stupid and didnt test it between these actions i cqnt say which one did the job or was both needed.
1. I cleared "paired devices memory" from my alpine stereo.
2. I cleared paired device list from my handset(opo)
Hope this will help someone else in future who got proplems with alpine receiver and opo.

Problem solved! bluetooth pairing and buffering issues
Hey problem solved
I had bluetooth pairing and buffering problems and now everything works perfectly. what I did was flash OPO_OxygenOS_1_0-modem-flashable.zip (you can find it somewhere in google docs..don't remember the link)
anyway after doing that everything works perfectly.
I am running cyanogen 12.1 nightly build from 20150601
then I flashed the modem.

Technical solution...too much ?

Hello All,
I too was facing issue with the Bluetooth connectivity. My headphone "Jabra Halo Smart" worked perfectly fine with other android devices but my OnePlus One. Issue i faced was that my at times my headphone would get detected but the headphone controls wont work. It was really irritating as i could not use the functionality of my headphones.
What i did was went into the Bluetooth options. Clicked on the setting icon beside my headphone and unchecked and rechecked the options.
Another action i performed was un-pairing the Bluetooth headphones from my device and resetting my headphones paired setting.
Third option was resetting the Jabra app that i installed on my mobile.
Fourth action is restarting your OnePlus device.
The above actions i performed in different orders. So one of them should surely help.
Suggestion provided by OnePlus Call Center: (which i did not need to try )
--> switch off the device
--> Press power+vol down button simultaneously
--> Select English language
--> wipe cache partition
--> wipe cache
--> reboot device
Advice while using Bluetooth headphones or speakers (especially Bluetooth devices having the functionality to connect multiple devices)...switch off the Bluetooth device and then switch off the Bluetooth of the host device (mobile, laptop, etc) and then connect the Bluetooth device to the other host device
Do not keep two host devices Bluetooth on...at times it causes to store the connection setting in the cache causing the Bluetooth device to act strangely. :cyclops: :cyclops: :cyclops:

[px5] bluetooth and torque issues

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.

Android One blutooth issues

Hello,
I have a Nokia 7 and my wife a MiA1 both in Android One (android 9) and we are unable to connect to the bluetooth of our car (a Kia Venga). My son have my previous Mi5s (android7) and he can connect to the car. First problem was that I didn't see the car bluetooth but it is now resolved activating "Show Bluetooth devices witout name"
Now when I try to connect at the time when my phone ask for PIN code, the car indicates "Pairing Fail".
I can connect my UE Boom bluetooth speaker without any problem. I can't connect my pool photmeter tester (BT detected and pairing refused).
I have tryed to reset network parameters without success. I have tryed too all bluetooth solutions found on Internet
Could you please help me. Is there a mean to downgrade bluetooth to the android 7 version?
Thanks for your help
Yann
