[Q] Bluetooth A2DP/Track Titles

I searched and couldn't find another thread about this so here goes...
Got a new bluetooth car stereo and my music and calls sound great, but my EVO doesn't transfer the track title/artist/album info to the stereo for some reason. I know it's not the stereo itself as my friend paired his BlackBerry and it showed the track titles. Tried this in stock music app, DoubleTwist, PowerAMP and unrooted on 2.2 and rooted w/CM7. Thanks in advance!
EDIT: Possibly just answered my own question but if anyone can confirm that would be great...it looks like the EVO only supports AVRCP v1.0 so far?? And if so, is there any way to upgrade the BT profile to 1.3 or 1.4 to allow for metadata transfer? Again, thanks in advance.

Yeah... the evo bluetooth profiles fail.

I'm currently using PowerAmp and love it...I know that metadata xfer is and has been working for stock player for a while, but does anyone know if this feature is available on any ROM besides AOKP? They're dropping support for us :crying:

If you're using a new phone with bluetooth 4.0, AVRCP 1.3, metadata transfer will not work until the music player devs update their programs. A rooted phone may work. For non rooted we are at the mercy of the devs, and poweramp has been promising an update for over a year now.

Bluetooth and Galaxy Nexus

Hi guys, question. My Nexus plays music through my aftermarket stereo fine through bluetooth but my annoyance is that the info doesn't show up. ie artist name, songs etc. While my ipod shows it all. I've read that it's just bluetooth firmware on the stereo/iphone/android but it's still such a pain in the a** that Iphone has the benefits while Android being better doesn't get as much. =( My question is do any bluetooth guru's out there know of a workaround or way to have info show up. My next step is trying different players etc.

The data needs to be sent by the application playing the music. I've found that Apollo will send this data to the screen on my 2012 Civic, the stock player does not.

I think certain ROMs have the latest bluetooth firmware. I think CM9 does? Not positive. I would also like to know if there was some way to update the firmware, on any ROM.

My GN wont connect for Bluetooth Audio (A2DP bluetooth receiver plugged into car ipod dock) - I have tried and tried, different roms, etc, no luck - my 3 year old Droid X works just fine, but my 8 month old Nexus wont connect - WTF. I enter password, get error that unable to pair.
My phone pairs to the car bluetooth phone no problem, but will not pair to audio.
Any suggestions???
Thanks!

Bluetooth AVRCP 1.3 - Cannot hear media

so... I think I've narrowed down my issues with newer ROMs coming out and my bluetooth not working in the car anymore. just a little background information,
- 2011 Toyota Camry SE w/ JBL Audio
- Verizon Galaxy Nexus using various ROMs
prior to any newer releases, I would use voice/audio over bluetooth, ran great without a problem. I didn't get metadata on screen but was ok. pandora, spotify, notification sounds, google music, etc... worked like a charm.
well... now I noticed that only voice calls & google music work over bluetooth connection in the car. I thought this was first an issue with pairing the device to the car, so I deleted all the profiles in the car and redid connection on phone. I still couldn't get sound out of any other media application i.e.; pandora, youtube, notifcations, spotify, etc... I could only get google music to work correctly. the apps not working look like they are playing, I turn off bluetooth on phone and it continues playing, but when bluetooth is on I hear nothing.
so after researching, I see that majority of new releases include AVRCP 1.3 which pushes metadata to the displays. I noticed this now works with google music, but I can't for the life of me figure out how to get other media services working properly. I've researched on RW, Google, other Android forums and can see some have similar issues, but the thread soon dies. [/background]
can anyone tell me if I can use an updated ROM with AVRCP 1.0 instead of AVRCP 1.3 to test? does anyone have suggestions I could try to get other media services working? thanks!

I think it's AVRCP 1.3 in CM 10 based roms that breaks this. I just switched to jelly belly 9 (4.1.2) which rolled back bluetooth profiles back to AVRCP 1.0 and pandora etc. works but without media info obviously. I also saw a AVRCP 1.3 patch for Pandora somewhere that may make it work. It's possible that the problem isn't that the ROM is not compatible, but that the Apps aren't.

Ok... I've confirmed it has to be AVRCP 1.3
Last night I took advice. I installed Jelly Belly 9 "4.1.2" w/ reverted AVRCP 1.0 because of BT issues, and this morning I went to work, tested connection with BT and everything worked! So... Looks like the issue lies with AVRCP 1.3. I don't see metadata on screen anymore but it doesn't bother me, I'd rather have all other media players working.
To touch on what others are saying, statements Google Music works perfectly fine with AVRCP 1.3 based ROM's as well as voice through BT. It's just the other media players i.e; pandora, slacker, youtube, notifications, etc.... that don't work. I'm guessing from what I read, is that the applications do not support AVRCP 1.3 and will not push to Toyota head units properly. Not sure if this is going to get fixed or not, but sucks because this limits what I can/can't use for ROMs at least a solution was found and reason why. Thanks bud!

You could also try https://github.com/loganakamatsu/PandoraAVRCP for the Pandora patch. Maybe patches exist for other apps as well...

I read on another thread that any app that supports the Scrobble Droid API hxxp://code.google.com/p/scrobbledroid/wiki/DeveloperAPI will pass the meta info to AVRCP. So I assume if you install ScrobbleDroid app hxxps://play.google.com/store/apps/details?id=net.jjc1138.android.scrobbler&hl=en from the play store any app that it is compatible with will also pass the meta info to the display.
As noted, Pandora is not supported as it does not broadcast its intents. I personally had issues getting the PandoraAVRCP github to patch. If anyone has a patched pandora.apk, I would certainly appreciate a PM.
Good luck.

Anyway to force bluetooth metadata to send to my car?

I have a brand new 2015 Hyundai Sonata, and my girlfriends Galaxy S5 can send metadata and track info to my stereo no problem (using google play music). My new Galaxy Note 4. refuses to send the track info... I've tried using the AutoAudio app which will allegedly fix the problem, but that didn't help. I also tried using Poweramp and the stock music player as well, hoping that something would work, and nothing does. However, my dash unit and steering wheel can CONTROL the phone, just not display what it's doing.. So it appear AVRCP is working but not bluetooth metadata.
It's such a minor thing, but it's driving me nuts. Any ideas?

Bump -- I also noticed the sound quality over bluetooth (for the same files) is way worse with my Note 4.

I get the same problem on my 2012 Mazda 3. My understanding is it's a problem with Bluetooth 4.1 compatibility. It makes no sense as it is supposed to be backwards compatible, but it's pretty regularly reported that many car stereos aren't fully compatible with the latest Bluetooth spec and this is the result. Bothers me too. If anyone is able to get it working, please share. I'm certainly interested in a solution.

So Hyundai themselves actually called me and said that my headunit is running some really old Bluetooth stack... So old that the new version of bluetooth isn't that far backwards compatible.. It will play audio, but at a lower quality and without metadata.. They said the headunit software manufacturer (MNSoft) might have a firmware update, but they generally only do those for nav systems.

I googled MNSoft and what showed up for me was the mapping software that Hyundai uses. Would that really have to do with Bluetooth and metadata? I have a 2013 elantra with nav. I get no metadata on my screen either. Sound quality is great though since mine does come with the upgraded sound system.

2011 mazdaspeed with nav here. Same results. Haven't called for update

Last I heard from Mazda, they can't (or won't) update the software. They consider it done. I find that aggravating as cars should last longer than phones and the radio isn't easy to change out

No streaming metadata while using Bluetooth streaming.

When on oxygen is can see the song that's playing on Spotify on my radio of my ford fiesta mk7 2011.
But when I flash all of the roms Bluetooth streaming works great but the radio don't show the song title.
What can be the cause of this, i tested with various settings but nothing really helps.
Someone got ideas where to look to fix this problem? Or how to fix this?

I assume you're already in Oreo? This is a well known Oreo issue.
I suffered this on my Nexus6p when I upgraded to 8.0 and 8.1.
When I switched to OP5T, the same thing happened after the 8.0 update.
I heard that this metadata issue does not occur on Google Play music. But like you, I prefer Spotify.

Hi, are you still having BT metadata issues?
Try this:
Go to Developer Options, and look for Bluetooth AVRCP Version.
On Android 8.1, this should be set to 1.4, but you should see an option for 1.3. Set it to 1.3.

Hi! Just came across this thread here on the forum. I currently have a Volvo V40(2017) and it worked flawlessly with my iPhone 6S through Bluetooth. Every app I used to stream managed to get the metadata there, that being Spotify, Apple Music or even Twitch!
I ditched the iPhone and bought a OnePlus 5T and now when I do pair the device with the car and stream music through Bluetooth this happens to me. The only thing shown on the car monitor is Audio Streaming without any additional information about it. I already tried every single Bluetooth AVRCP version available (1.4[Default], 1.3, 1.5, 1.6) and not one works. Also I'm currently using Apple Music but I don't think it matters because other applications also don't pass the metadata as well.
It's really annoying not being able to see what is currently playing and its also the only thing about my recent iOS to Android change I'm sad about so far
Any other ideas on how I can solve this?
Thanks!

I feel your pain.
Back in 2014, I had a nexus phone that was running on Kitkat. And in addition to the song metadata, etc., I am also able to use my car's voice dialing function to make calls on my phone. But when Lollipop came out, my car's voice dialing suddenly stopped working. But at least I could still make calls and I still had metadata.
When marshmallow came out, my car's dialer suddenly stopped showing the profile picture of the person I'm calling (or calling me). The clock sync function also stopped working. But at least I can still make calls, and I still had my audio-track metadata..
Up until Nougat 7.0, the audio metadata still worked.
It was when Nougat 7.1 came out that I lost the metadata.
When Oreo came out, it was a hit-or-miss affair. Sometimes I get metadata. Sometimes I don't. I could not figure the correct sequence that I followed to get the metadata to work.
I was lucky enough to find the AVRCP tip from a Honda Car forum.
I'm sorry I don't have any other ideas at this point.

i have Pixel 3xl with Android 10, - Bluetooth connects fine there is no metadata - song info. this problem started with 8.1 Android version and I have not been able to get it to work. I really cant believe google cant fix this issue or even aware of it. plenty of threads on google. I think they all use Iphone, i am guessing ...this is very annoying. I have change the avrcp version from 1.4 to 1.6. no luck, also I read that turn off battery optimization on Bluetooth. no luck. any suggestions would be appreciated
