I have tried connecting several different LiDARs to my Pixhawk 2.1 via serial but i keep getting the same issue: Bad LiDAR health and no readings.
LiDARs i have tested are Lightware SF02, Lightware LW20, Benewake TF03. I have also tried the CAN option for Benewake with little success.
I have double checked all connections (reversing both tx/rx) and have tried powering both from Pixhawk and from external power source.
I have also double checked all necessary parameters incl.
SERIAL1/2_PROTOCOL (tried both telem1 and telem2 ports on the Cube)
I have read from an old forum post to check the RNGFND_LANDING parameter but I believe it has been removed from newer versions of AC. I also tried going back to AC3.3.3 and AC3.4.5 and testing but with no success.
I am currently stumped and not sure how to proceed, any help would be greatly appreciated!
