Blue Tooth Tag Support Broken after update of NOKIA 6 2017 (TA-1021) to Android 9

Recommended Posts

After update of NOKIA 6 2017 (TA-1021) to Android Pie,  Music Tags are not displayed anymore in Car Audio via BT.   The DDB2 music app still shows the tags of the music file via BT on android Pie.

Try turning off all of the new the Android Auto options in PA, as sometimes on certain ROM versions they can clash.

Tried that to no avail.  It worked only once in the car after a factory reset of Android Pie.  But then all of a sudden it stopped working...

The following fixed the issue:

1. Enable Developer options in Android 9

2. In Developer menu change AVRCP to v1.3 instead of default 1.4.

3. Turn off battery optimization for Bluetooth app in system settings.

Thanks for the update. Hopefully that might help Max track down and repair whatever Google did with Android Pie.

2. I'm or Oreo but only have AVRCP 1.5 or 1.6 over and above 1.4  ....

3. By the BT app, you mean Poweramp?

On Oreo 8.1 I had no problems with BT tags on my BMW 3 touring (2015) so I never checked the settings in developer options.

By the BT app I mean the BT system service, only visible when you choose "Show System".

OK. Difficult to know if this is Poweramp or the radio I have (Kenwood KMM-BT302, a couple of years old but on the latest firmware). I've tried to reset the PA bluetooth settings to 'default' and the PA audio settings to 'default' (in Advanced Tweaks). I've tried all 3 AVRCP profiles I have in the developer settings on my phone (AVRCP 4, 5 and 6) but none of this gets me artist/track etc on my headunit. What did work briefly was when I did a hardware reset on my headunit which caused track info. to appear for a few moments after which it reverted to 'situation normal' which is showing track number and track run-time.

I'm leaning to the conclusion that it's actually the HU that's the problem, based on past experiences and the number of BT issues people mention online with BT and car HUs which turn out to be the HU fault. But if someone can convince me I'm wrong please step forward ......

Have you tried disabling all the Android Auto features in PA?

Settings > Misc. May not solve your problem, but one or two people have reported turning them all off helps with BT data content.

Right, found them. But no change. Still only trrack number and elapsed time on the display. Still leaning towards the HU though. It does work fine on the wife's Honda HU in her car. That runs on a custom version of Android 4.x ......

For what it's worth, my Hyundai BT car headunit displays only the track title and artist name, no track number or running time at all. And instead of the album name and cover art (both of which it shows in its local USB file player mode) just the BT device name (e.g. "Andre's Galaxy Note 3") is shown. Stupid design or what?

For Android it's usually resolved by unpairing and pairing the device (car headunit) again.

Probably not that as I have to repair every time I change ROMs on my phone. I've done this several times since installing PA 8xx but I'll try and remember to test this tomorrow. Thinking about it I don't 'delete' the pairing from the HU, just re-pair so I'll ensure I delete from phone and HU before the re-pair process.

Nope. Deleted the pairing on my phone and turned BT off. Deleted the pairing from my car's HU then turned everything on and paired again. Still just the track number and elapsed time showing.

 

So, I did a little test. Cleared out the 'BT last processed commands' list first. I started PA with no BT devices nearby and chose a new track on 'pause'. Turned the car HU on and waited for it to connect to my phone (connecting is set to automatic but takes 30 seconds or so). Started the track and played about 5 seconds. Hit 'pause' on the PA screen on my phone then turned the car HU off. Below is the complete list of 'BT last processed commands'. There's always the chance that I'm doing something wrong/have something set incorrectly so I wonder if someone more knowledgeable with BT could point anything out? The HU is a Kenwood KMM-BT302.  Thanks.
