Armbian Linux v6.1 - Bluetooth not working - no BT controller found

[SM2027]

Armbian Linux v6.1 - Ubuntu 24.04 (Noble) with XFCE seems not to support full bluetooth controller at boot stage, we need to manually load hci_uart module and and attach it to the serial interface. Is there any other service that is required to be enabled or any overlay that should be checked? 

 

After boot, we need to execute some commands to get the BT controller alive:  

 

user@bananapim7:~$ hcitool dev
Devices:


user@bananapim7:~$ sudo modprobe bluetooth

user@bananapim7:~$ sudo modprobe hci_uart


user@bananapim7:~$ sudo btattach -B /dev/ttyS6 -P bcm -S 115200 &
[1] 3405
Attaching Primary controller to /dev/ttyS6
Switched line discipline from 0 to 15
Device index 0 attached


user@bananapim7:~$ hcitool dev
Devices:
    hci0    F0:23:AE:09:82:E3

 

Thanks for your help!
