Bluetooth DIsconnect Problems?

[RTP]

From time to time my previously well paired bluetooth headphones refuse to keep a connection to my Pinephone.

No matter how many times I rebooted/upgrade, systemctl restart bluetooth, off/on bluetooth back and forth connect attempts repeatedly w/intermittently stopping of bluetooth on the phone. Still, no bluetooth connection sticking (with previously setup and working well bluetooth headphones).

When I viewed systemctl status bluetooth in terminal, I found this (MAC OUI left as is):

Code:

Dec 10 17:03:03 mobian bluetoothd[485]: sap-server: Operation not permitted (1)

Since this has happened to me numerous times (seemingly completely random), a simple fix is to completely remove the previously setup bluetooth device on the Pinephone, and then readd it from scratch:

Code:

bluetoothctl

In bluetoothctl I entered:

Code:

remove FC:58:FA:X:X:X

After removing the device completely, I was able to reconnect by starting the pair over again from scratch.

I used bluetoothctl (there is also a "Remove Device" under Bluetooth settings in Mobian).

I don't know if this helps anyone or not, but I am sharing in case it helps someone shares the same frustrating problem. Outside this Bluetooth has really improved in functionality (besides the weak connection mentioned in another thread).

To add: I am really happy with the noticeable progress (to think, just a few months ago, no bluetooth headphones were usable, now I rarely experience problems).

Great progress. Now I can listen to Podcasts without a problem (tip: set podcasts to use Lolipop to prevent sound cutouts on 'blankscreen').
Thank you to all contributors!

Thank you for this, I have been using VLC for podcasts and I get the random bluetooth disconnect. It is with the screen off and is anywhere from 5 to 7 minutes. When I turn the screen back on the sound emits from the speakers but plays, stops, plays, stops, etc. I will try Lolypop, do you also use gPodder?

Yes, Gpodder for managing my Podcasts and Lolipop is really nice for playing them.  It has a great interface. You can see me using Gpodder and Lolipop starting at 1:47 of this video: https://youtu.be/Z_Cuhuu2xwI

On default app, not only does sound cut on blank screen, another thing I noticed (in the default player on most Phosh) is it doesn't even have a visual representation of the pause/play buttons. So the default player I would have to poke around with my finger until it found the pause button.  

Definitely give Lolipop a look.
