Bluetooth connection suddenly stops

uConsole
1

Can any of you give me some advice on what the problem might be?

I’m using Bluetooth in-ear headphones that work fine with a laptop. When I connect them to the uConsole, the connection drops after about 10 to 15 minutes, and trying to reconnect results in the following error message:

“Failed to connect to Bluetooth device - GDBus.Error:org.bluez.Error.NotReady: br-connection-adapter-not-powered”

When I restart the uConsole, the connection works again for a while.

It’s the trixie image and a CM4. From SW pov bluetooth is enabled and switched on.

Thanks for any hints!

Possibly some hidden power saving option kicking in ?

Yes, thanks. I think that might be it. I’m currently looking for the right solution on Raspberry OS. I’ll report back later…

Apparently it was the power-saving feature.

I added the option `usbcore.autosuspend=-1` to the `/boot/firmware/cmdline.txt` and now the bluetooth connection stays alive.
