I have searched the existing open and closed issues

Required Information

  • DietPi version 9.12.1
    G_DIETPI_VERSION_CORE=9
    G_DIETPI_VERSION_SUB=12
    G_DIETPI_VERSION_RC=1
    G_GITBRANCH=‘master’
    G_GITOWNER=‘MichaIng’

  • Kernel version: Linux DietPi 6.12.25-current-rockchip64 #1 SMP PREEMPT Fri Apr 25 08:48:08 UTC 2025 aarch64 GNU/Linux

  • Architecture: arm64

  • SBC model: Orange Pi 3B (aarch64)

  • SD card used: I’ve got two installations, one on a generic SD card, the other on internal nvme drive; both have same problem. Both fresh install with updates.

Since not every distro recognized the internal bluetooth adapter, i’ve got additional BT dongle: tp-link UB500; it was automagically recognized by each and every distro – so far.

I am very happy with my Dietpi installation. Added MATE desktop, it is snappy and everything works as expected – except Bluetooth. And BT is very important here, this machine is used for languages learning and we need to connect a special BT keyboard.

zeebee@DietPi:~$ blueman-manager
Gtk-Message: 14:23:45.679: Failed to load module "canberra-gtk-module"
blueman-manager 14.23.46 ERROR    Manager:147 on_dbus_name_appeared: Default adapter not found, trying first available.
blueman-manager 14.23.46 ERROR    Manager:151 on_dbus_name_appeared: No adapter(s) found, exiting

Been googling for solutions, everything was a couple of years old, pointing out to oudated kernel.
Will appreciate any input. I am willing to provide more info, or try some workaround.

Did you have a look into dietpi-config for enabling the internal bluetooth? (Probably this option is not available on your SBC, I’m not sure, just have a look)

Otherwise to check for the BT stick, let’s see if it is recognized at all:

lsusb

If yes. let’s check if the sytem tried to load the driver:

sudo dmesg | grep -i bluetooth
