Problem with Bluetooth pairing

I have a bluetrek S2 headset, Since I flashed my MDAC III to WM6(B&B) I'm having problems keeping the headset and my device paired. I flashed WM6.1(B&B5.0) to the device but the problem still exist. I can pair them to each oter, and everything works fine. When I turn of the headset( to recharge or to save battery) The connection is lost the next time I turn it back on, I do have to pair them again. First I tough it was my headsets problem, but then I tried to pair a BT GPS mouse, the same result. I have the same problem pairing this GPS with other devices(TyTN, iMate Jamin) running WM6. Does anyone know how to fix this bluetooth problem I'm having?

There might be a connection here (no pun intended). For quite sometime, I was using an old SE637 phone and had it working flawlessly with my Garmin c550 GPS.
During an hour and a half trip yesterday, the Garmin notified me 3 times that the bluetooth connection with the Tilt was lost (the SE profile had already been removed from the Garmin). I never saw this message before with the SE. FWIW, the 2 devices are no more than 2 or 3 feet apart at all times, and neither of them are physically touched during the trip. I'm concerned that this might be an HTC problem. Any thoughts?

No one with an possible solution, or at least with the same problem??

Same problem here
I have just received a new HTC TyTN II on Orange that has the same problem. My old one (windows mobile 6.0) had no problem with my Motorola H12, but the new one (Windows Mobile 6.1) can't keep the pairing, and I have to turn Bluetooth on an off to get the connection. Always have to enter the passcode.
Version data is:
CE OS 5.2.19212 (Build 19212.1.0.3)
Processor: MSM7200-400MHz
ROM version 1.65.16.25
G 25.83.40.02H
D 3.28.00.00
Any help /advice much appreciated!
O.

Fixed itself...
This seems now to have fixed itself - I had to enter the password twice in a row for some reason and then it worked properly. So now all happy...
Windows Mobile 6.1 rocks...

Bluetooth not alive when phone is locked?

All,
I have this small issue with my HTC Desire and the Parrot CK3000 Evolution. Until now, everything works perfectly (calling, sending contacts, voice dialing, ending calls,...)
However I have one small issue. When I enter my car, and my phone is locked, the Desire will not pair with the Parrot. From the moment I activate the screen, pairing is done within a few seconds. I already tried to leave it there for half an hour, no pairing, touched the screen, pairing within a few seconds.
It looks to me like the bluetooth is not active / alive when the phone is locked (or in sleep). From the moment the pairing is done, everything works fine, also when the phone is back in lock / sleep.
Anybody has anything similar or has a solution for this? I searched the market for some kind of Bluetooth-keep-alive application, but could not really find it...
Thanks in advance,
Best regards,
Speedygerre

Small bump, nobody any idea for a solution or somekind of workaround / app?

I have a similar situation with my Audi A5 (factory BT kit).
It will connect when the phone is locked (screen off etc) but it can take anything from 1 to 10 minutes before it does connect.
Like yourself, my Desire connects immediately if the phone is not locked.
Strangely, it appears to work OK in my Mazda MX-5 which has a Kenwood DNX8220BT system (Bluetooth, SatNav, Ipod, coffee maker etc) - and the Bluetooth is a Parrot system. Having said that, I haven't used the MX-5 much since I got my Desire so it might not be a representative sample.
There is definitely something amiss though.

I have a Parrot CK 3100, and whilst I am happy to report that I do not have the same problem as you, I did have a problem syncing my contacts.
Check out this site, and download the software to udate to the latest firmware. You will need a laptop with either built in bluetooth, or a seperate bluetooth dongle.

I updated the firmware on mine, and now my contacts sync properly.
There is a good chance that updating could fix your connection problem as well.

Sorry forgot to add, that updating the kit really is a doddle, but their software is Windows 32bit ONLY and definitely no MAC!

Thans pergolesi, I hope your suggestion workshop, I will try it when I have some time one of the next days.
However I still think it has something to do with the Desire, since syncing workshop perfectly when Desire is not locked...

I don't know about the Bluetooth but I know my wifi deactivates after about 5 minutes when it's locked even though I have it set to never turn off. Maybe the Bluetooth is doing the same.

Perhaps not much help, but I sometimes play music from my Desire on my car headunit using Bluetooth streaming, and that continues to work fine when the screen goes off and the phone is locked. It also still responds to commands from the headunit (skip, pause, etc).

Once it's connected, everything works OK for me as well, it just is the connecting moment which apparently does not always work

Can I ask what year your A5 is? I've got a 2010 A3 and BT doesn't work properly with my Desire I can get it to pair, but then it will disconnect a few minutes later and the only way to reconnect seems to be to unpair/repair or switch the car off/on. When it IS working it can make calls, etc. fine - but I just can't get it to stay connected I tried my Audi dealer but they just said it's not on the Audi list and there's no update to support it, so interested to hear you got it working on your A5.

My A5 is a 2008 model with SatNav and therefore MMI High. The Desire paired straight away with no problems and both the car and the phone remember each other - it just takes awhile sometimes for one or the other to realise it and connect.
I'm pretty certain that it is the phone that has the problem as I had no such problems with several Sony Ericsson phones previously.

Thanks - interesting. I wonder how many different BT stacks Audi run - I was hoping they'd share some common code and therefore be updated quickly but it sounds like this isn't the case given that it's working fine on your A5. Thanks for the info though!

[Q] Bluetooth Upgared / Fix

can anyone tell me if I can update the Bluetooth in my HTC Desire or have more profiles. the phone is branded o2 but can be rooted. I dont want to change anything else in the ROM just make the bluetooth connect automaticaly & reliably to the car.
There are newer software builds available but have no mention of updating bluetooth.
Ther are no OTA updates available.
Software Number is 2.14.207.1
Andriod 2.2
Thanks for any advice in advance.
Trampsdad

Can't you just pair the 2 devices together? I personally don't use Bluetooth so no idea on that aspect. Also, the software is so out of date because o2 cba to release and update. There are major updates since yours. It might be worth considering to root so then you can flash a newer ROM, or infact, you don't need to root and just use an RUU. With the newest software. No need to root it then and less chance of it mess up.
Hope this helps

I still have some strangeness with Bluetooth. From what I read there are some updates in Honeycomb and maybe gingerbread. But I don't have a feeling what you are looking for is in FroYo
Sent from my HTC Desire using XDA App

Well I have a Kenwood Headunit with Bluetooth and the connection to that using stock Froyo and LeeDroid showed some interesting results. Gaps in the phonebook for instance. However, putting a 2.3 ROM (Ginger Villain) sorted that out, its fine now.
Bluetooth depends on the other device too.

What exactly is the problem you are having?
What Car do you have?
What Bluetooth system is installed (is it standard)?
I have used my desire in a number of cars (Vauxhall, Ford, BMW) without any isses with pairing, using the Phonebook,etc. is a different matter.

Personally, I have just received a new BMW 528i, and it doesn't get on well with my Desire at all.
It pairs OK and can use both the phone and music, but when I leave and return to the car, it just refuses to auto-connect again, and I have to go through the pairing procedure again.
Oh, except one - the time I went back to the garage to 'complain' about it and ask for advice, when it worked perfectly. Until I got home again!
Have experimented with my old Nokia N85, and that works fine, too. So it's either the Desire or an incompatibility between it and the car.
Oh, my Desire is running MCR r9 (FroYo) at the moment. Are there known issues with this? Info on any Bluetooth updates I could apply would be gratefully received!

i have to enter my pairing code every time i connect my bt headset - i took this to be a quirk for the moment - hoping its fixed in 2.2.2/2.3.x etc.

Im having this same problem also with a Pioneer Head Unit in my car.
Bluetooth has always been troublesome as it doesn't auto connect. It will connect if I either manually click on "Pioneer Head Unit" or turn Bluetooth off and on (which I automate with tasker).
The pin thing is new and happens with all roms I have tried except LeeDroid, (which I prefer not to use as I don't like sense much). Leedroid still has the auto connect problem.

Some good hints there - thanks!
I can connect far more reliably if I initiate the connection from the phone than from the car.
Likewise, if BT is switched off on the phone and then turned on after the car is on, then it sometimes works, too. Certainly don't need to re-pair anywhere near as often.
Can I ask how you use Tasker to automate the BT switching? I've not used that (I use Setting Profiles instead which I understand does roughly the same thing), so am curious what kind of rule you have that's useful for this.
Cheers.

I use the following rules:
On wifi connection turn off bluetooth
On wifi disconnection wait 30 seconds and turn bluetooth on.
If not wifi connected & not bluetooth connected turn bluetooth off and on every 5 minutes.
If not wifi connected & not bluetooth connected and incoming call turn bluetooth off and on.
If not wifi connected & not bluetooth connected when display switched on turn bluetooth off and on.
The battery drain hasn't been a problem, if I go away or won't be using my car for a while I disable tasker. Of course this doesn't help when it keeps asking for the pin.

Ah, cunning! Of course...toggle it when it's not already connected. Prifile Settings doesn't seem to let me toggle things like BT directly, although I could probably do so by setting some appropriate profiles.
I'll have to experiment...or just buy Tasker, instead!

True, but so far in my case, I've only had that when I've tried to initiate connection from the car. Hopefully your trick will mean I don't need to do that so often.

Anyone found a gingerbread rom (or any rom!) with improved Bluetooth?

I have found the bluetooth to be terrible on the desire. I have got about 3 devices that my phone just refuses to pair with.
Currently I am trying to get it to connect with an Elm 327 Obd scanner. No luck, it asks for a pin, then I enter the pin, but it immediately rejects it.
I have tried oxygen rom, leedroid, stock froyo, everything...
I also have a parrot hands free kit that does the same thing, asks for pin, then does nothing...
Something makes me think it might be the radio or something. Except that my phone DOES connect with my scala motorbike helmet... So frustrating

[Q] Phone Freeze using bluetooth

Hello,
i have a problem with my Galaxy S4 Mini (i9195) when i use bluetooth in a car similar enviroment.
The first call is provided well.
After the first call waiting maybe 5 min, my phone gets very slow and a secondary call will not be shown in my handy until i disable/get out of range of my bluetooth device.
I have latest firmware (XXUBMJ7) rooted and tried kernel_v1/2.
What information can i provide?
Thanks for your help

I am sorry.
Problem is solved by using the bluetooth dongle in an other usb slot.

[Q] Intermittent issue connecting to car via Bluetooth

I have a new Note 4 (Verizon) and a 2011 Kia Soul. Prior to the Note 4 I had a Note 2 (Verizon) that I paired with my car for the last 2 years without issue. I am able to successfully pair the Note 4 and the car and use all of the Bluetooth functions I would expect to work. The problem is, often (not 100% of the time), the next time I try to connect the phone to the car that connection fails. I then have to unpair and re-pair them to get them to connect. Neither side gives me anything useful in the way of error messages.
I'm at a loss as to how to troubleshoot this further. Is there a way to pull Bluetooth connection logs out of the phone?

I have the same issue, but worse. I have a 2011 KIA Sorento, and a Samsung Note 4. The Bluetooth connectivity is very intermittent. One minute is works and then stops. One minute it plays music fine and all of a sudden, the music will start going in and out, like a bad cellphone call and then disconnect. I try to reconnect and it won't. I've gotten in the car and it works great and the next time it works like crap! I've been on a cell call, talking through Bluetooth and it will automatically disconnect, but still shows connected. I have to switch to speakerphone to talk and then it all of a sudden reconnects back to Bluetooth. Does anyone know if this is a known Samsung issue? I saw a previous post from Dec 2014 which stated, " Apparently, the Note 4 and Edge all use the newest AVCRP 1.5, which nobody else uses yet. Nissan told me that they were told by Samsung, that in their next update, they're going to revert the phones back to AVCRP 1.3, which is the standard in the industry." Has this occurred?

I had the same kind of problems with my Galaxy S 6 on my 2013 F150 with Sync. I was only able to fix it by getting rid of the S6. The Note4 I had before (on 4.4.whatever) and the Note4 I have now (on 5.0.1) have no issues.
