    BlueTooth is not working Yocto Intel AeroBoard

    trgiman

      Dear all,

       

      I would like to use Bluetooth to communicate with external devices, BLE should be available trough Intel Wireless 8260 chip. But it is not working in Yocto?

       

      root@intel-aero:/lib/firmware# dmesg | egrep -i 'blue|firm'

      I described the situation also at:

       

      Accessing BlueTooth on Intel AeroBoard · Issue #361 · intel-aero/meta-intel-aero · GitHub

       

      Where we can get the missing files? Or how to solve the situation. Thank you.

          Hello trgiman,

          Thank you for your interest in the Intel Aero Compute Board.

          Can you please try the below commands? 

          1.  sudo systemctl enable bluetooth followed by reboot
           After the board starts again, use:
          1. bluetoothctl
          2. agent KeyboardOnly
          3. default-agent
          4. power on
          5. scan on
          Please provide me the outcome in case you receive any errors. 

          Regards,
          Eliza

            Hi Eliza,

             

            Output of bluetoothctl  is always only:

             

            Waiting to connect to bluetoothd...

             

            Ok. Than I started bluetoothd directly from /usr/libexec/bluetooth

             

            Now bluetoothctl returns [bluetooth] command line

            But after trying your recommended commands or command list returns empty list and on your recommended commands it returns:

             

            agent KeyBoardOnly

             

            --> Agent registered

             

            default-agent

             

            --> Default agent request successful

             

            power on

             

            --> No default controller available

             

            scan on

             

            --> No default controller available

             

            dmesg output changed a bit, but still driver errors?:

              Hello trgiman,

              Thank you for your patience!

              While the Intel Dual Band Wireless-AC 8260 has the capability, Bluetooth is not enabled for the Intel Aero platform. If Bluetooth is required for your project there are alternative interfaces for an add-on Bluetooth adapter. 

              Please let me know if I can help you with anything else!

              Regards,
              Eliza
