Nokia bluetooth headset bh-503 issue(?)

Hello xda,
I recently bought O2X and i tried to connect my bh-503 to it.
The device doesn't pop up in the bluetooth menu on my stock O2x.
Any thought ?
The BH503 is running over bluetooth 2.0 EDR +A2DP.
Thanks in advance

Isn't the o2x able to handle bluetooth 2.0 and EDR ?

same headset, but works fine here.
i've used it on stock rom and almost every version of mcr so far without problems.

Do you press the "on/off" button until the blue led light blinks? I have a BH-501 and a B-505... No problem... Sometimes the most simple thing it's... complicated... LOL

Wow,
that was the trick....
I totally forgot the long press thingy!
thanks !

Hello,
I do have a similar problem with Nokia BH-105. Once I updated to the last CM ROM (10.1), I could not make call any more.
With the BH-503, I'm facing similar problems.

[Q] A2DP streamning to Dension Gateway BT

Hi!
I have installed a Dension Gateway 500s BT in my Audi A6 and streaming music (like spotify) from my friends Iphone 4s via Bluetooth works like a charm. When i try my Samsung galaxy s whit CM 10 (from 14-oct) im not getting any sound out of it. I have used my phone earlier for Bluetooth headset communication whit my audi and it works but now i just se the call in my car but the sound is stuck in my galaxy. Any suggestions to this? i have red about the bit rate and according to dension manual it should be 41000 and i have chekt my audio_policy.conf for A2DP and its sample_rate is 41000. i dont know if this issue is related: http://miuiandroid.com/community/threads/bluetooth-a2dp-streaming.18121/. Could it be i have to try a diffrent kernel?
Any suggestions appreciated!

Did you ever figure this out? Im' looking at buying a Dension adapter and need it to work with android.

OnePlus 3T Bluetooth Volume

Hello guys,
This will be my first post on XDA. I have been reading the forum for quite a while even though I am currently using an Apple device. I have used both Android and iOS devices, and acknowledge their pros and cons.
I have always liked to mod my devices (this goes as far back to my Sony Ericsson K550i). This includes jailbreaking iOS and fiddling with Cydia tweaks and Android rooting, flashing custom roms etc. I am posting this in the OnePlus 3T forum (because I am considering to buy it) but it applies generally to all Android devices. So my question is:
-Does the OnePlus 3T sync volume with bluetooth devices the way iOS devices do (the phone controls the volume on the device and the device can control back the volume of the phone)?
I am asking because I am using bluetooth devices all the time (bluetooth headphones and speakers) and the Android devices that I have tested so far do not support that feature. It usually goes like that: you have to set up the volume of the phone and the bluetooth device separately and with many devices this causes not only inconvenience, but also worse performance (i.e. if you set the device all the way up there is an audible hiss, or the DSP is not working properly depending on the volume level). If it isn't a built in feature, can it be added somehow (fiddling with system files, flashing something, installing something additional)?
So far this is one of the major things that is holding me back onto my old jailbroken 5c (iOS 8.4) . I really hope there is a nice solution

Most Android devices on Android 6.0 and above should natively supported Bluetooth volume syncing. Though I find that this only applies to reasonably modern Bluetooth devices. While my Bluetooth headphones (~3 years old on BT4.0) can control my phone's volume fine, my 4 year old Bluetooth speaker cannot (5 yo, BT2 or 3?).

I read that they introduced the feature in 6.0.1 but then removed it in some version of Nougat + introduced volume reset (to 50%) when you connect to a known device. I tried my roommate's Galaxy A5 (running 6.0.1) with my Sony XB3 and it wasn't syncing the volume. Now I have replaced the XB3 for JBL Charge 3 and will check it out as well but I feel that the bluetooth implementation is a bit hit and miss. I mostly care about the JBL Charge 3 (Bluetooth v4.1) and Jabra Revo Wireless (Bluetooth v3.0) volume sync.

I use an app called Trigger (much weaker version of Tasker) to change the Bluetooth volume to the ideal level for each Bluetooth device I connect.
On two occasions now, my headset's volume fell out of sync. I'm not sure what caused it, but re-pairing fixed the issue.

I did further research on the topic. It appears that the problem lies in AVRCP and more specifically the version that Google uses in Android (1.3). It hasn't been updated for years and it is still the same
even in the latest Nougat. This is a topic that I managed to find out: code google com/p/android/issues/detail?id=186433 (insert dots because I cannot post links before reaching 10 posts)
It is really a shame that Apple devices have been supporting the newer revisions for so many years and that Google doesn't give a damn about it. Since this is XDA Developers can someone come up
with a solution for the problem that can be implemented on different Android devices? Please

My Jaybird X3 adjusts the volume in sync on my 3T running OOS Nougat, but on my Moto X Pure running Marshmallow, I have to adjust the phone and Bluetooth volume separately, which was annoying.
I never tested it on OOS Marshmallow though.

[BLUETOOTH] Help! Bluetooth is severely buggy!

Okay, so first things first:
My device is running OOS 3.5.4 and is rooted.
The issue I'm facing is that when I connect my 3T to my car (Hyundai Verna 2016 if it's necessary) via Bluetooth, the phone starts spazzing out and lagging like crazy until I switch off the Bluetooth. Also, when I try to play music from Spotify, it plays but no audio is heard from the car's system. I am 100% sure it's not my car's fault because my other phone (Asus Zenfone 5) connected just fine and played music from Spotify with ease. I'm extremely clueless as in what could cause this issue. Can my fellow XDA buddies help me out on this one? Any help is greatly appreciated!

Comment to resurface this post.

why aren't you running the latest version of oxygen os? 4.1.3?

You say you are using OxygenOS 3.5.4 and you are rooted. This makes me believe you are doing it because 6.0 is more "mod friendly", and you are probably using Xposed and/or Viper.
VIPER4ANDROID is known to cause the exact same behavior that you mentioned. Probably easiest to flash a custom ROM with it already built in like Freedom OS or Audax.

Update your ROM
You need to be running an updated version of OOS. There have been many fixes and improvements to Bluetooth connection and reliability and I haven't had any of the issues you describe. Below is the list of Bluetooth connections I make on a weekly basis and I haven't had any problems running OOS 4.1.1 and 4.1.3:
1. VW car stereo (phone and audio streaming)
2. Nissan car stereo (phone only)
3. Panasonic home phone system
4. Plantronics Voyager Bluetooth headset
5. Dell laptop computer (data transfer)
6. Sony portable speaker

Question Bluetooth not pairing with Corsair RGB Virtuoso XT

Recently purchased.
Zenfone 8 specs: "Bluetooth® 5.2 (EDR + A2DP), supports LDAC, Qualcomm® aptX™, aptX™ HD, aptX™ Adaptive, AAC"
Corsair Virtuoso XT specs: "Bluetooth 5.0 and supports the default SBC codec, as well as AAC, aptX, and aptX HD".
Headphones pairing as expected with previous phone (Huawei Mate 20) showing in phone "aptX HD", so headphones are ok.
Zenfone 8 pairing as expected with my car's bluetooth, so Zenfone 8 bluetooth is "working".
Tried with android 11 > developer mode > all possible combinations with parameters AVRCP & MAP bluetooth version.
No tried again after updating to Android 12.
Any clue?
Any of you having same issue?
Thnx and Cya

There can be compatibility issues with devices, apparently. My Zenphone8 will find and pair with a new Lenovo P11 tablet, but will drop the connection after 2 or 3 seconds. All resets and setting changes do not work, although no bluetooth issues with other devices. The Lenovo service people say it's a compatibility issue - so back the tablet goes, I need the hotspot, and I like this phone.
Previously I've had the same problem with a Sony phone and a Huawei tablet, where the Huawei service also told me "compatibility problem".
So it seems that some devices just won't talk to each other. It's possible you have a similar problem?
