    @Alex-Kushleyev This is the results I get from running px4-listener esc_status and capturing the results of running px4-qshell voxl_esc status.

    @Chase-Riley, your output indicates that the ESC driver in PX4 is communicating with the ESC, I do not see any issue with that!

      @Alex-Kushleyev Not sure what happened but you are correct it is functioning now.

        @Matthew-Wellner , the baud rate is 2000000 (2Mbit), not 200K, can you please double check your PX4 params?

        Also, some helpful commands:

        px4-listener esc_status
        

        this will print out the esc_status message, which the ESC driver should be sending out

        Also, if you run voxl-px4 in foreground

        systemctl stop voxl-px4
        voxl-px4 -d
        

        then you can open another terminal / adb and run:

        px4-qshell voxl_esc status
        

        this will print status of voxl esc driver and the params (in the window where voxl-px4 -d is running)

        Interesting - px4-listener esc_status gives me "never published".

          When I run and the motors don't spin up here is what your second set of commands gives me:

            I also watched as px4 started up and it looks like the process fails to open the port for the ESC (see the red after the voxl_esc start command) -

              @Matthew-Wellner your ESC baud rate in PX4 params is 200,000 , not 2,000,000 which is most likely the issue.

                the failure to open the UART port is most likely due to unsupported baud rate (200,000) instead of desired baud rate (2,000,000)
