      @Alex-Kushleyev I may be experiencing the same issue. I will tag along here.

      @Eric-Katzfey I responded in our thread about the spectrum error thinking this might be linked to it, but this is very similar to what I am seeing. So it could be a linked to this instead.

        @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.

              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)

                          @Matthew-Wellner , no worries! I am glad you got that part working.
