I can not run a Lidar SF20 with APM Quad v3.5.3 firmware.
Mission Planner displays “Bad Lidar Health”, and “sonarrange” remains at zero.
I installed it in I2C then in serial setting as explained in the wiki (with the right electrical beams), I even tried with an older firmware v3.4.6, but nothing works.
Dropix from Drotek (Pixhawk 1)
I tested the lidar alone with Lightware manufacturer software and it works.
Should I set up the lidar with the Lightware software before installing it in the drone?
Do you have any idea where the problem might come from?
My next goal is to use it with an IR Lock for the Precison Landing and use the Terrain following.
I have attached a log file with APM Copter Quad v3.5.3
Thank you in advance for your help !
