Lidar Lite V3HP + Pixhawk 2.1 + Mission Planner

I’ve been trying to use my Garmin Lidar V3HP with my pixhawk 2.1 via I2C and it worked for a few minutes when it was conected like recommended in Ardupilot.org (picture) but after I turned the system off I couldn’t get any data from it anymore. To check if the lidar was working I used an Arduino and it worked fine with it but never with my Pixhawk. I also tried to get a read via PWM also unsuccessfully. After checking that the sensor was working I tried to use pull up resistors like recommended in Garmin’s manual (picture) but it didn’t work too. I also tried to invert the SCL and SDA cables position in the conector. I’ve been using a life battery (6,6V) to power the sensor. To check if it could be an over tension issue I also tried with a 5V BEC which also didn’t work.
The parameters set in mission planner were like recommended (pictures). I also tried every single type in the parameter RNGFND_TYPE.

Does anybody have any ideia of what could be happening?

Hi igor23,

First it’s important to know that this is experimental and might or not work.
We suggest to use the guide available HERE.

Try that first and let us know
