    Hello,

    Currently troubleshooting some issues with the FPV ESC not being detected when using voxl-esc scan and voxl-esc detect. The FPV ESC is receiving battery power, powering the VOXL 2 as expected, and its LED pattern shows nothing out of the ordinary. Here is the output from voxl-esc scan and voxl-esc detect.

      @Jeremy-Frederick , please check the following:

      • try explicitly stopping PX4 before scanning for the ESC using voxl-esc python tools : systemctl stop voxl-px4
      • try another 4-pin uart cable, if available
      • test another ESC the same way, if available

      Was this ESC + board combination working before at stopped working?

      Alex
