Android 12, Bluetooth mouse

Edge2
1

Hi there,
For android 12, Bluetooth mouse is not able to connect to edge 2 after edge 2 comeback from sleep mode, I have to turn off the bluetooth and turn it back on again to connect to the mouse.
Maybe this has something to do with the power saving? The “Bluetooth radio” is deactivated somehow?

Please help
Thanks.

No bluetooth remote seems to be able to reconnect automatically after waking from sleep, not even ChromeCast 4K or a Xiaomi remote.
Also button presses on bluetooth remotes can’t wake device.
It seems to affect all RK3588 devices and a bug in Rockchip code.
