[Q] Bluetooth problem after upgrade

When I bought new car in May, Hyundai ix35, everything between Desire and car worked flawlessly: paired within 1 minute, phone book transfered in 3-5 minutes ?btw, why it had to transfer whole phone book everytime?? and reconnected automaticaly after out of range or car stereo off/on, voice dialing ...
BUT, after upgrading to android 2.2 I'm experiencing a lot of problems: no automatic reconnection, can connect only when car is started and phone bt after that, phone keep thinking that is connected even car is miles away, phone (application) restart after almost every call when bt is connected. I've tried with unpairing and pairing devices again, but there is no difference.
Car didn't have sw upgrade only phone.

Bluetooth incar needs constant repairing for in car stereo

I have a HILUX that comes with bluetooth.
For some reason every few days the Bluetooth won't connect automatically, I am required to disable and enable bluetooth on the DESIRE HD 3-4 times so that it connects fine. If it doesn't work then I have to repair again and the issue comes back again in another few days.
Is anyone experiencing this issue also with any of their bluetooth devices?

Yes I have some issues with bluetooth and the handsfree kit opel cd70 it connects but after a cople of seconds it disconects
For me was it gingerbread I downgrade it to froyo and it worked for me

Mine has not done this with my Jawbone Icon, Motorola S10-HD stereo headphones or my Volkswagen Tiguan. Perhaps you might try another bluetooth device?

buletooth issue?
I had try different device and do the same thing, like my audi q7 and jarba headset and the garmin. Can you tell me what buletooth setting you are using?

Mine has intermittent issues as well, I'm using an older Motorola 710 BT earpiece. I'll only turn on BT on the phone when I know I'm going to use the earpiece, such as when driving or needing to be hands-free. I only activate the earpiece after enabling BT on the phone, but there are times when the earpiece does not connect.... the only fix is to reboot the phone. Is that similar to the issue you are having?

I'm having issues connecting to my car. If I reboot the phone and connect it will work. But once it's disconnected and I turn bluetooth off and then back on from the phone, it will not connect. Only way to fix it is to reboot. Don't know how to fix the issue. Never had a problem connecting my Sensation to my car's bluetooth.

My issue is similar in turning bluetooth on and off via the power widget and not being able to re-connect to my bluetooth earpiece after a few cycles. I'm wondering if it may be an issue with it being BT 2.0 versus BT 3.0 on the phone?

I thought it was my car but a lot ppl is having this issue too.
Sometimes it wont connect but it says connected so i have to go to BT settings and click where it says connected n overwrite the connection for it to work if not gotta restart the phone. :/

I'm having problems with a SoundFly FM Transmitter in my car.
At first it took forever to pair. And even when paired & connected it's really glitchy.
I'm using this mainly for GPS turn by turn over the car sound system. But because it is glitchy I can't use it because some of the directions get cut off.
I had a MyTouch 4G before. No problems whatsoever. I don't if it's a hardware or driver or BT device issue.
I'm willing to get a new FM Transmitter but not if it does the same thing.
It didn't work well on stock or rooted w/ Juggernaut rom

this is quite annoying. I wonder why this topic died so quickly, there have to be more people with this problem? Maybe has something to do with a bluetooth power saving sleep feature? Streaming music, pause music for a few minutes, incoming call gets connected but I get no sound through headset.

Bluetooth to car

Hey everyone,
I have a Sony aftermarket deck in my car that I connect to via Bluetooth on my GN (also used to use my Nexus S, Droid Incredible). I have had the same issue with all my phones (a friends iphone doesn't have the issue) and the deck, which is when I turn Bluetooth on in my phone, sometimes it will auto connect, other times it won't.
When it will not connect I have to cycle the Bluetooth on/off a few times then go into settings and keep clicking the deck players name to get it to keep trying to connect.
Anyone else ever encounter this and if so, how did you solve it?
Thanks

I had this issue too (Nexus One to my Kenwood DNX-8120). The way I get mine to always connect is to start BT BEFORE you start your car's radio. Then, it should auto-connect without any problems. I've been doing this method now for about a year without ever having a problem if I go that route.
If you still have troubles and don't want to turn your phones BT on and off, try turning BT on on your phone, but turn your stereo off and back on.
Hope that helps!

Bluetooth goes in and out

Got my AT&T Galaxy Note II. Have left the ROM, bootloader, etc. all stock.
Where my Galaxy Nexus would have trouble uploading my phonebook to my 2012 Honda CR-V car stereo without Navigation system, the Note II seems to pair without issue.
HOWEVER, if the phone is unplugged from power... about once every two minutes it drops the BT connection from the car stereo, and about 20 seconds later reconnects. I say if unplugged, because if I plug the phone into a cigarette lighter charger, the BT seems to stay up and stable.
I figure this could be a BT timeout issue, or perhaps some power setting we could adjust? I have disabled the power management functions on the Note 2, but that has not prevented the issue from occurring.
I also have a Sony SmartWatch that I have paired to the phone. The watch doesn't have any issues, but whether I have the watch on or off, I see the same functionality between the phone and the stock car deck.

I'm having the exact same problem, I thought it was an issue with my vehicle's Bluetooth antenna.
I tried calling Samsung about this issue and they were, as expected, pretty unhelpful.

I'm having a similar problem with my Ford Sync Bluetooth connection. Except I'm only using battery power.. The first time I connect for the day, all seems fine. Any subsequent connections during that day are problematic with connect failures or random disconnections.. Must be a gnote2 bug as my gnote1 (stock ROM) worked perfectly in my car.

As soon as I read this, I began to wonder if my issue is somehow related.

same problem here with SGN2 and Veloster...I lose my connection after a few minutes. Before with my HTC, I had no problem .

BT works fine for me in my MDX stereo and on my BlueAnt device. I don't have to plug it in or anything... just turn it on, pair it and go.
My note 2 is bone stock - just rooted so I can use Titanium Backup.
