Bluetooth not working - EVO 4G Q&A, Help & Troubleshooting

Every since I upgraded to Fresh 3.5 my bluetooth is not working. I'm using the BlueAnt Q2 headset and for some reason it can't pair. My phone can't find it and the bluetooth can't find my phone. I tried connecting my laptop to my phone and that works fine. Any suggestions?

I had the sam issue with MIUI Rom. All I did was change the Kernel,and that work for me. Try that it may work for you.

I have the same, tried Doomkernel, ICS stock and various Rom's (stock, arconium) but all have the same. The pairing with my bluetooth headset works fine but when I try to pair with the car audio (random PIN) the PIN pop-up never shows. With another car with a fixed PIN it works flawless again.
Got the same problem, doesn't pair with my car bluetooth after installing ics arconium on my arc s. With 2.3 this worked flawless.
i got the same problem too when i installed ics
Hey all,
I found a solution for my car bluetooth.
I renamed my car to 1 word (Don't know if it necessary) and I changed my code to 0000. After that my phone connected without asking for a password.
Have Problems with CM9.0 for Arc. My Sony Ericsson MW600 connects but Audio still works over Phone Speakers.
But with Stock Sony ICS Beta Rom it works fine.

how can u rename "my car to 1 word"?
how can u "changed my code to 0000"?

I've got the same problem, using a Blue&Me system from Alfa Romeo/Fiat.
It generates a random pin and the device is called "blue&me". Won't pair, doesn't even prompt me for a pin code.
Can't rename the car or specify a pincode there.
So help !

[Q] Multiple device over Bluetooth issues since ICS

Situation:
I'm using a Xlink bluetooth gateway in my house to connect my phone with and I also have a Mazda CX-5 with integrated Bluetooth system with the latest update from TomTom and Mazda. In the Mazda, I use the Bluetooth mainly for the phone, but occasionally use it to stream audio.
Phone:
T-Mobile samsung S2 x SGH-T989D with ICS 4.0.4 (Rogers leak)
Issues:
At first (With official Gingerbread)... everything was working fine. Both device paired and all functionality worked.
Then, applied official ICS update from Kies software ICS 4.0.3 and Bluetooth issues started. I first paired my Xlink device. So far it worked. Then tried to pair my Mazda, everything was really slow but managed to have it work. Turn the car off, get back in the house and the phone is now able to pair with my Xlink device, but cannot connect as a phone audio. Even if I go manually in the Bluetooth menu and try to activate the Phone audio it wont work. Only way to have it work again is to unpaired the Mazda and reboot.
After reboot, the phone works great in the house with my Xlink device. Going back to my car and try to pair my Mazda. Same issue. The phone does pair with the Mazda, but I'm unable to make a call since the phone cannot activate the Phone audio.
Look online and have tried the ICS 4.0.4 (Rogers leak) and same issue with Bluetooth.
The only way my devices works perfectly is when I only pair with one device at a time. There is something happening when you pair more than one device, even if not both device are turned on or in range.
Anybody got the same issue or a fix to that?
Thank you and sorry if my post is a little long... but that issue is the only thing that make me not enjoy my phone.

[Q] BlueTooth & Cars

I've tried to connect my phone via BT to two different cars and have no luck. It will scan for devices but won't find them at all. Does this happen to anyone else with the SIII? Strangely enough, it finds and connects to my JamBox is just fine.

Still rocking the stock and unrooted for the phone. I tried on a Lexus GS and a Scion xB but no results show up. How do you connect manually? I should try that
Phone calls and bluetooth streaming works fine in my 2009 Mazda 6 (GT, no navigation). My phone is stock + root.
I use Slacker Radio everyday, launched by Automateit Pro when the connection to my car is established.
IIRC, I had to input a PIN on my phone, then in my car to do the pairing, and after that, I had to connect the phone manually to the stereo, but only once. After that, it's automatic when I start the car. Watch out for the "Only visible to paired devices" setting on your phone. It must not be checked.
I too have major issues with bluetooth, my phone connects whenever it feels like. I had to flash to cm9 to be able to listen to music in my G37. No problems in my other car (it has aftermaket pioneer system).
PS Just flashed the CM10 since they finally figured out A2DP, but the image is broken. (Note to myself: "Read the thread before flashing") Will wait for the next nightly build.
Nissan's always had a horrid BT stack in it. I'm in an 09 Altima and BT just sucks. I know it's not the phone as I've tried multiple phones from multiple vendors and they all suck. Nissan won't fix it either.
[Q] Bluetooth issue with Cars
I have AKOP Rom and KT Kernel. My bluetooth connectin to Mazda Cx-5 is fine. However, the problem I have is a lot of phone information (Song title, Battery Status) I used to have on stock, now are gone. Previously, I can fast foward or Rewind a song, also, once BT is connected, the default music player will start automatically
Can someone suggest a BT manager app which can change and enhance BT setting?
I have a 2009 Mercedes B200. My phone connects to the car just fine, but no sound comes from the speakers and no sound goes into the microphone. Same thing with my car and the HTC One X, although that was fixed with a stock ROM update. Bluetooth on cars can be very hit and miss.

Bluetooth issues with car stereo

Hello there. I've been experiencing a problem with my OP3, regarding the BT connection to my car stereo.
I recently bought a new head unit for my car, a Pioneer MVH-X580BT unit, it Works fine. However, when i connect my phone to it, it allows me to playback áudio, but i won't allow me to use it for hands-free calling. The Bluetooth menu on the phone says "MVH-X580BT - Connected (no phone)". It happens with any CM-based rom that i've tried so far.
However, when i install a stock rom (Oxygen OS, Freedom OS also works), it works just fine, both audio and phone mode.
Is there something in custom roms that changes some sort of parameters in the ROM that makes the phone refuse a phone mode connection from the radio?
Any tips i can use?
Thanks!
logcat of the incident:
Here.
Hope it helps.
I've had the same problems. It's an issue with the LOS BT stack. I've created several unofficial versions of my favorite ROMs using a different BT stack that fixes this problem for me. Let me know if they work.
