I just bought my Raspi 4 and tried to connect my Bluetooth Keyboard to it.

It Always works for About one or two seconds and then disconnects immediatley.

Both for normal Bluetooth (Raspbian)
and for Blueman.

I searched several Forums but i cant find a solution for this. :(

There is another thread reporting the same problem here: https://www.raspberrypi.org/forums/view ... 6&t=254523

No solution yet unfortunately.

Same issue - bluetooth kb won't connect for more than a few seconds any more. Was working fine since launch until recent update.

Logitech K380 keyboard.

Hoping engineers are aware of this pretty please...

Trying to narrow down the problem...

I got my Pi4 on 18/9 and bluetooth was working fine for some time after. Now 'bluez' and the userland bluetooth software haven't been updated in that time, so the problem must presumably lie in the kernel or firmware. Unfortunately I've run 'rpi-update' a couple of times and I'm on the 64-bit kernel so I don't know at what point the bluetooth keyboard stopped working. Is anyone able to narrow the timeframe down further?
