      @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)
