Hello.
My Lidar lite v3 is connected to Pixhawk through I2C.
The binary is built by “make px4fmu-v2_lpe” with recently pulled git source code.
Lidar is successfully connected with simple change of “rcS” (ll40ls start pwm -> ll40ls start i2c) and able to see DISTANCE_SENSOR.current_distance value through QGC.
The problem is lidar distance value has too much noise.
Even not armed staystill position, it’s randomly fluctuate from 9 to 27 when distance between lidar and floor is 17.
As it’s unstable the PX4 log shows " lidar fault, beta XX.X" and “lidar OK” frequently.

Does anyone had same issue? or any idea how to fix this?
Is this only v3 problem? or I miss something.
FYI, lidar is powered by BCE.
