Trying to connect Samsung soundbar over bluetooth on Odroid N2+

Hi everyone,

I’m having troubles connecting/pairing my Samsung hw-q930b soundbar over Bluetooth.
I have my Odroid connected to my beamer over HDMI and because there is no cable to the soundbar I wanted to send the audio over Bluetooth to the soundbar.

Hardware list:

  • Odroid N2+ (CoreELEC installed on EMMC)
  • Samsung hw-q930b
  • Bluetooth ASUS USB-BT400

Software tested:

  • CoreELEC (official): 20.2-Nexus
  • CoreELEC (nightly) 21.0-Omega_nightly_20230716

Debug log


  • Pair
2023-09-20 10:15:32.972 T:3726    error <general>: ## CoreELEC Addon ## bluetooth::dbus_error_handler ## ERROR: (Authentication Canceled)
  • Connect
2023-09-20 10:15:37.410 T:3726    error <general>: ## CoreELEC Addon ## bluetooth::dbus_error_handler ## ERROR: (br-connection-refused)

I can connect my phone to the soundbar, so no issues there. I also tried to connect my Bluetooth Sony headset to Odroid and that is working. So, seems like there is something specific in the Odroid <-> Samsung soundbar connection that is not working.

Thinks I tried

  • Tried nightly build
  • Tried with other devices
  • Tried to connect over ssh session with bluetoothctl
  • Banging my head against the wall multiple times

I also read on a forum that changin /etc/bluetooth/main.conf ControllerMode to “bredr”. But it seems that I can only open that file in read-only mode.

Any idea what the problem might be? Maybe I need a different Bluetooth doggle?
Also, if any more details are needed, let me know!

Thanks in advance!
