Hello.

I am trying to connect LIDAR-Lite v3 to Pixhawk by PWM for Alt_Hold and FlowHold flight mode.
But It dows not work well.

I setted Pixhawk as below.

  • ArduPilot Copter 3.6.3, Quad X
  • I setted parameters according to wiki guide.
  • I wired Pixhawk and LIDAR according to wiki guide.
  • LIDAR is not died. I checked with two LIDAR-Lite v3 but behavior is same.
  • I made a cable for PWM connection.
  • Connector cable is conducting very well.
  • I setted parameters SERVO5_FUNCTION and SERVO6_FUNCTION to Motor5 and Motor6 for my purpose.
  • 5V BEC is connected to servo rail (AUX1).

Mission Planner shows sonarrange = 0.
dronekit-python Vehicle.rangefinder return None.

Do you have some idea to improve this problem?
