BPi M2M Magic: AP6212 Bluetooth? (on Ubuntu 20.04)

[Robert Winkler]

Hi, I try to build a  Stenogotchi (https://github.com/Anodynous/stenogotchi), using a Banana Pi M2M Magic board (https://wiki.banana-pi.org/Getting_Started_with_M2M).

I managed to install the Ubuntu image and to upgrade it to a recent version (20.04 LTS).

UART and Wifi are working, but I can't get Bluetooth. For my use as virtual BT keyboard, Bluetooth is critical.

The hciuart.service fails; but rfkill lists a bluetooth device:

root@Stenogotchi:/etc/apt# rfkill
ID TYPE      DEVICE             SOFT      HARD
 0 bluetooth sunxi-bt      unblocked unblocked
 1 wlan      phy0          unblocked unblocked
 2 wlan      brcmfmac-wifi unblocked unblocked

root@Stenogotchi:/etc/apt# bluetoothctl
Agent registered
[bluetooth]# power on
No default controller available
[bluetooth]#

Any idea?

Best, Robert
