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.

What custom rom bypass car audio bt issues?

Hi all,
like many 5T users I bothered problems with bluetooth connection in car audio system (spotify and calling). I've tried everything what I found on forums (downgrading software, clearing cache, energy settings etc.) but with no success. Finally I red somewhere that problem is OOS itself and custom rom should do the work. My question is: what custom rom should I use (on my earlier phone (samsung note 3) I used Ressurection ones)? Did someone tried this way and could tell about results?
Im on cnp and everything seems fine when I connect to my truck.
Thank You for fast reply, but did You experience bt problems on car audio system earlier (with official oos)? And what is cnp?

Codename Phoenix rom
What problems? I've been running oos all long and no issues with my car bt.
Problems with bt connectivity (spotify does not work - stuttering and disconnects and calling also). On official forum it's a popular problem and has many potentially solution. None works for me so far.
Many problems with my car BT (mercedes w211) with TugaPower ROM (now on v26.0)
After the initial connection car reports no (mobile) signal but I can manually dial. Automatic / voice dialing does not work.
Almost on every call BT disconnects and I have to redial. I make the call and few seconds into it, it drops call back to the phone with the car radio reporting "waiting for BT connection"
I tried to look into the logcat but I see no related error(s).
I'm also looking for a good rom that works with my car BT.

Bluetooth and WIFI interference on Xiaomi Mi 6

Hi everybody,
since I bought my Xiaomi Mi 6 last year I am having the following problem:
If I am using WIFI and connect a bluetooth audio device the connection always lags drastically and it is not possible to listen to music properly.
I didn't have this issue on my LG G2 before and in addition, other people who use my WIFI in combination with the same bluetooth devices do not come across this problem.
Furthermore there is no such thing if I am using my computer to listen to music via bluetooth.
Is there anybody who has noticed the same problem and found a proper solution?
Thanks in advance!

MIUI 11.0.3 Bluetooth connection problem

Dear All,
I have bought this phone 1 week ago but I have problem with the bluetooth connectivity. When I would like to connect the phone to a bluetooth car device the pairing code request dialog not shows up and because of this the pairing fails. Do you have any solution for this? With Redmi Note 4 (MIUI 11.0.2.) the car works well. I tried it with other car devices but there was the same problem.
Thank you in advance!!!!:fingers-crossed:
Try going to Settings-Apps-Manage apps-Bluetooth and Clear data-Clear all data. It helped me for some time but now Bluetooth problems appear again and I have to do it every time after answering the call while listening to music via Bluetooth.

Hi! try changing your AVRCP version from 1.4 to 1.6 in developer options
Thanks for reply! Unfortunately it does not work! The pairing request dialog window is still not popping up...

Maybe you need te change the bluetooth notification priority to high and maybe check permisions.allow it to show on home screen etc
Thank you for everyone! I found the problem! The app of my bluetooth watch caused the problem, after uninstalling it the bluetooth works again.
I face a similar problem with skoda car infotainment.
In my case pairing is successful but on the first call connection breaks. Even if connection is broken and car's infotainment starts seeking for a Bluetooth connection Redmi note 8 thinks it is still connected and it stucks there. when connection breaks a message pops up that reads something about AVRCP not supported and redmi note not responding
A have unpair both devices many times but same thing happens again and again.
I have to point that i came from a Redmi note 6 pro, where EVERYTHING regarding bluetooth connections and multiple connections were operated just fluently. I have redmi note 8 just 2 days
On redmi note 8 are always connected an amazfit stratos and a meizu ep51 handsfree and there are some other apps installed like mifit.
Do you thing that i should start first by unistalling all apps?
i unistalled amazfit app and it seemed that was getting better but i assume that phone it cannot deal with multiple bluetooth connections. Unforunately it cannot managed android auto (wired connection) and car infotaimnet (bluetooth connection). On the first call connection drops.
I flashed a custom ROM- based on China roms- but things didnt got better. Having both redmi not 6 pro (which handles all bluetooth connections just fine- even transfering active call via bluetooth headset to the car infotainment as soon as it establishes a bluetooth connection while i am getting into the car) and Redmi note 8 on developer options i copy all setting from Redmi note 6 pro to Redm note 8 but all issues are still there.
I wonder if it can be used the bluetooth app from the Redmi note 6 pro to the redmi note 8 but i dont have the knowledge to do it
I have the same problem. It sucks that redmi note 3 which i had before worked 100% ok...
All these issues make phone quite useless considering that everyone goes wirelessly. I wonder if this disappointing case is claimable from Xiaomi.
just noticed the same problem, both of my RN8pro bluetooth mac is 00:00:46:00:00:01 which is nonsense.
maybe you all got the same mac as mine, which is generic mac.
How can I check Bluetooth mac address ? Do I think there is something can be done?
Settings > about phone > all specs > status.
There's a bluetooth mac near the bottom.

I checked my Redmi note 8. It's seems normal, 28:16:7f:b5:65:2b is it?
MIUI 11 - Android 10 version?
The only workaround i found is to keep one connected bluetooth device at a time. So before i get into my car i have to disconnect bluetooth headphones and reconnect them after. Bluetooth management of Redmi note 8 is a big mess. I assume that is a phone's hardware problem its incapability to manage two or more bluetooth connections simultaneously.
I contacted Xiaomi customer care regarding bluetooth issues and i was finally asked to perfrom a test. I wonder how a test could resolve it
In the attached screenshot in developers options the max connected audio devices option is 2 but it's deactivated so i cannot changed it eg to 3. Could it be the solution to bluetooth connectivity issues? Is there any way to activate this option and change it?

Bluetooth, 4G connectivity and notifications issues

hi everyone,
(i posted a similar message to another thread which might be obsolete)
my previous phone was a redmi note 6 pro and now i run a redmi note 8.
On both phones are installed the same apps, same use and same connected devices.
Issues on redmi note 8 (runs MIUI Global 11.0.4 PCOMIXM Stable):
1. it cannot maintain bluetooth connection (initially is connected but connection breaks as long as a call takes place) with car's infotainment . I've read that smartwatch app might cause the problem, in my case amazfit, which is true but i do need both amazfit app and bluetooth connection to my car. I changed AVRCP from default 1.4 to 1.6 but didnt help. Any help?
2. While redmi note 8 is connected to bluetooth headset (i've checked meizu ep51 and mi sports) all text message notifications sounds go through the headset not the phone. Notifications settings are checked. I think its a wider issue. A workaround is to disable media audio for specific bluetooth connections but you can not listen music thru the headset then.
surprisingly Redmi note 6 pro handled all aforementioned successfully.
3. mobile internet connections is often interrupted (for an unknown to me reason) and i have to switch on-off airplane mode to restore internet connection

nope
in addition to all these issues i realized that from some apps with all necessary permissions given there are no notifications at all. Another issue is that DND seems not to work. No matter if DND is enabled or not by AutoDND option, sounds are active unless i turn on or off manually
I wonder if a custom ROM is free of these bugs, but which one?

why don't you try flashing the stock ROM with mi flash via the fastboot method and then see if these issues still exist.

In case the ROM hasn't been flashed correctly?
Does it make difference from downloading the latest package by the updater menu?

Yes you can update from updater app too...but it's much better if you flash via mi flash fastboot method as it's a much more clean flashing and also it flashes all the partitions... fastboot flash is known to solve some issues...make sure you have a backup of your data .... you'll also need an unlocked bootloader but that's not an issue as you can lock your bootloader again if you want to while flashing via mi flash

I have the same issue, can you solve it?

No , i have no solution of anything. I reflashed phone's same ROM, no hope.
I look for a custom rom hoping it would be bug free
Same problem here ( Redmi Note 8T MIUI V11.0.3.0.PCXEUXM)... Using Notify & Fitness for Amazfit with my Amazfit GTR and connection is unstable, every now and then connection is lost. Also transferring watchface is taking long time, about 10 seconds for 1%, and on my old Huawei it is about 1 second for 1%. I also tried another watch, but same problems. Tried every AVRCP setting (1.3, 1.4, 1.5 and 1.6) but same issues. Has anyone tried custom ROM or maybe MIUI EU? I'll try but have to wait 1 week for unlocking bootloader.
I also have to wait one week to unlock my phone. Firstly I'll try a XTRV ROM which is China source based.
