Hey, we are trying to make Benewake TF02 Lidar work with pixhawk 4 (without success yet).
The TF02 lidar is connected to UART & I2C B port on pixhawk. Parameters are set as in this article http://ardupilot.org/copter/docs/common-benewake-tf02-lidar.html .
Sonarrange stays at 0. We have tried almost every parameter possibilities and checked whether connections are correct several times.
Does anyone have experience with this setup? Any help would be greatly appreciated.
