Bluetooth connections unreliable, particularly in the last month or two

Post by rmbjr60 »

I'm having very unreliable experiences with my bluetooth and/or sound subsystem in my Linux Mint 20.2 uma (ubuntu 20.04 focal).

I have several bluetooth devices, all of which have given me varying degrees of success: logitech keyboard, logitech mouse, Tozo T10 ear buds, JLab Go Air ear buds, and BT969 ear buds.

For the tests I've described below, the devices are confirmed to not be connected to any other device. Also, they are all known to be in perfectly good working order (for example, I have used all of them, as recently as 15 minutes ago, *without any problems* under Windows 10 on the *same computer* (it is a dual boot configuration). This rules out a hardware issue with the computer's bluetooth hardware or any of my individual BT devices.

OK, back in linux mint, the symptoms are many...

1) Sometimes a previously-paired device will not connect. It won't autoconnect (i.e., without initiating a connect from the computer), and it won't connect with the computer initiating the connection. I've used two apps in linux mint: (1) blueberry (I think that's the name of the app launched from the Cinnamon system tray - I'll just call it the "bluetooth gui") and (2) 'bluetoothctl' (v5.53), a command line tool for interfacing with the bluetooth subsystem.

2) Sometimes after a successful device connection, and the device shows in the bluetooth gui (and in bluetoothctl) as being connected, it cannot be used as a speaker or microphone by any app. It appears (IMO) to not be connected for "calls and audio". I've used various apps: Strawberry, Audacity, VLC, Firefox, Chrome, etc. I'm not totally up on bluetooth, but it seems that when a device connects it can tell the server what services it provides (e.g., speaker, microphone, keyboard, mouse, etc.) ... somehow this does not appear to be working under this symptom - otherwise my sound settings would show an earbud bluetooth device with mic as a possible selection for both inut and output. But it does not show up in either of these sound settings dialogs.

3) Sometimes, when not connected, but appearing in the bluetooth GUI as a paired but not connected device, attempting to click on the slider to initiate a connection with that device becomes untenable; the slider barely moves and quickly pops back into the unconnected setting.

4) Sometimes 'bluetoothctl show' reports "Powered: No"

Here are the infos from my system config and logs ...

Code: Select all

I have poked around in a few log files (e.g., /var/log/dmesg, /var/log/kern.log and /var/log/syslog). I found some messages relating to bluetooth, but I've no idea of their significance. These messages are included below.


[The following is from dmesg on a previous day. I don't recall which symptom I observed, but there are clearly some bluetooth-related issues]

... plenty of views, no replies. This sucks. I despise Windows, love Linux. But this is a f'ing show stopper. Cannot listen to my own music on my own desktop? ... Goodbye Linux. Hello Windows!

I have Tozo T10 bluetooth earbuds working fine on LM20.3 Cinnamon & LMDE5, using both Blueman and the LM bluetooth app.
Fully charge earbud charging case connected to a USB cable & USB charger.
Then fully charge earbuds in charging case.
Right earbud adjusts volume.
Test earbuds via LinuxMint. Turn volume up on LinuxMint PC. Play some music.
Test earbuds on your phone via bluetooth.

On Blueman, open app, right-click on Tozo, choose "Connect".

If that doesn't work, try LM20.3.
You could also try a LM live USB flash drive (the USB you used to install LM), then see if bluetooth works on a "live" session.

I would install "Blueman" in Software Manager.
Then install "blueberry" from here:
http://packages.linuxmint.com/pool/main ... .7_all.deb

Reboot PC.
Test bluetooth devices again.
Good luck.
