[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.

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 Also, the software is so out of date because o2 cba to release and update.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

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

Galaxy Nexus Bluetooth issues.

I have Galaxy NEXUS yakju, otad stock 4.1.1 stock everything. But every time I try to connect to my platronics k100 it doesn't show on the list. I have to reboot both devices several times before my gnex sees the platronics. I then go to pair the device but I get cannot connect to pk100 either wrong pin or passkey. I cannot find away to enter a passkey. I tried clearing the Bluetooth cache to see if that helps but nothing. Anyone else have this issue? Anyone have a fix? Could this be because of the new radio that dropped? I never had this issue with ICS.

I'm also stock 4.1.1 GNex. I had perfect BT behavior with several devices with ICS, now have a problem with my car's built-in BT hands-free phone (2007 BMW 328). Pairing is fine. About every other phone call I'm told they can barely hear me over the noise but my audio is fine. I've paired and unpaired, and I did a complete wipe before installing JB. Very frustrating since everything worked great with ICS. Also no problems with 2 other BT headsets and connecting to 2 different PCs via BT.

Hello,
Did either on of you find a fix for this?
Thanks in advance

[Q] Mildwild 5.0 - Bluetooth issue

I'm using Mildwild 5.0 as daily ROM. I noticed that even though bluetooth is on, the phone does not connect to the remote audio device.
The pairing process is successful, however the connection is not automatic.
I need to manually connect the phone to the device using the Wireless settings menu.
Did anybody notice the same behavior?

I had a similar problem with this ROM and my car's audio/phone system. I suspect the problem was on the side of my car's bluetooth, because after erasing the link on car's side, I was able to setup it again, successfully.

I'm still experiencing the same issue with MW 14.
My car kit is most probably a BT 1.1 device.

Here's the relevant logcat information

bluetooth pairing issues / delete paired devices

Hey guys,
since I bought my bluetooth headphones (Wearhaus Arc), which are actually pretty cool, I have lots of troubles with them.
When I paired my phone (HTC One M8 running latest official stock unbranded Android 6.0) with the headphones the first time, everything was great.
While using them from day to day I was faced with connection issues. That means, that both my phone and headphones are on, but it takes (almost everytime) a couple of tries to connect them. Even if I tap in the saved devices on the headphone, the connect could not be established. Turning off and on the headphones and bluetooth on my phone was the only way to fix it.
If I finally had a connection, everything was fine. In a few very rare cases, the connection worked at the first go.
Some weeks ago, a new firmware for the headphones was released, so I wanted to install them. During the update process, the updater (Android app) said, that the verifcation failed and the firmware cound no be updated. Same behaviour with the Windows 10 app. Even with another phone it did not work. Seems like, something is wrong with the headphones.
So I contacted the support again (first time they gave me the advice to use the Windows 10 app to update firmware) and told me, that I have to return it for repair. The gave me a return label etc. and I sent it back.
After waiting a few weeks I finally got it back. With zest I turned them on, but the joy was marred, because my phone did not recognize them.
Before sending them back, I unpaired the headphones in order to start over with the new ones. Maybe this was the mistake...
I did some pairing testing with other phones (HTC Sensation, BlackBerry Q10, HTC HD2), which found the headphones immediately and worked fine. So my guess is, that only my M8 has a problem with them.
Pairing, unpairing and "repairing" (pairing again) between my M8 and the other mentioned phones worked well, so there cannot be an general bluetooth issue.
After doing a factory reset on my M8 I'm a step futher, because now the phone sees the headphones (somethimes), but it isn't able to establish a connection. In case I see it, I tap on the available devices, the phone tries to connect, but a second later I get the message: "unable to pair. Make sure your devices are on and discoverable, and then try pairing again". Rebooting the phone does not work. I also cleared the data and cache of the bluetooth share app and performed a network reset like described here: http://forum.xda-developers.com/htc-one-m8/help/htc-one-m8-bluetooth-wont-android-6-0-t3340279
My question to guys is, what can I do, to get the headphones to work?
Is it possible, that on the phone is still a piece of information left about the former connection, which refuses any new connection?
Is there a file on the phone, which stores the bluetooth connections? if yes, maybe deleting or editing the file could help?
Thank you in advance!

Bluetooth always reconnecting in car

The problem is to connect Bluetooth on a Moto Z Play Android 7.1.1 patchlevel 2/2018 (current in reteu, was same result with Android 6.0.1 12/2016) with a Volvo XC40 car.
The first pairing with Bluetooth succeeds for a second. Then, nearly immediately, both displays (car and mobile) show reconnecting for about 10 seconds. It has a connect for a fraction of a second, and then is reconnecting and so on.
Trying flight mode and then only Bluetooth enabled on the mobile did not help. IIRC it showed some message about "My Volvo Carnull not bonded" (the name of the car for Bluetooth is "My Volvo Car" and some message with typo, something like "conecnting not successful". After that I rebooted, result was the state before with reconnecting.
Did try this several times. Also did try to reduce the amount of Bluetooth access types the car tries. There are 4 connected: phone, audio, internet, contacts. Did also not help.
Has anyone an idea how to get a successful connection or what the cause of the problem is? Did search for similar problems with Bluetooth in cars, but could not find anything (except for that hint with flight mode which did not help).

What I tried by now:
- Flight mode, only Bluetooth (as already mentioned). No change
- Remove all bluetooth connections. Pair new. No change
- Delete data for sytem app "Bluetooth Freigabe". No change
All other bluetooth connections are working fine. Another Moto Z Play using Android 7.0 (01/2017) is working flawlessly with that car. Strange for me is that it didn't work on 6.0.1 in the same way it does now fail on 7.1.1, but the other Moto Z Play using 7.0 is connecting stable.
Still the question: Does anyone have an idea how to get the connection working?

Factory reset?
I see that you deleted all bt connection but do you have some apps that are using bt? Like for smartwatch, headphones...?
I have Amazfit and watch must be connected to be able to pair a new device. Drow me crazy first time when I had that problem. I thought that car audio is broken, then phone... After pairing, watch doesn't have to be connected to reconnect.

I was afraid this reply could come. When doing a factory reset, I do following: Pack /data/media somewhere because Nandroid omits this. Backup all partitions using twrp. Backup all apk using adb. Export SMS. Export contacts. Screenshots of the launcher screens. All this takes about 2-3 hours. Then I struggle a week until my device behaves like before. I'd be willing to do it if I saw a reason why it could help.

Headphone, yes, there is August EP650 configuration tool that is not necessary. Thank you for the hint, will try it. Also I read somewhere it may help to delete cache partition, that's also worth a try before doing factory reset. Maybe I'll wait for Oreo before trying factory reset, could be they fixed some bug there.
Edit: BatOn which shows Bluetooth battery for external devices could also be the culprit.

That's a strange behavior indeed. Amazfit seems to do something wrong.

It doesn't get any better if you upgrade to Oreo, I've been having problems with my Moto Z play disconnecting and reconnecting to the radio in my Corolla constantly ever since I went up to nougat. To be honest I just bought a good pair of headphones and stopped using the radio. Good luck though, if someone finds something that helps let me know.

I'm using bt with car audio, headphones, smartwatch... No problems at all, except one with Amazfit. And that is related to their bt implementation, not Moto fault.

Seems the last action to remove Bluetooth related apps was the right one . There were two apps installed:
1. BatOn showing the state of battery of connected Bluetooth device
2. August configuration app for August EP650 headset
Removed both as they are usually not needed and it seems to work now. Will see later if it only worked for the short test I did today (currently I try to avoid driving because of an injury) or if it keeps stable.

Good, you didn't have to factory reset after all
