I need some help with this. I’m converting a hexacopter from Ardupilot running on a Pixhawk 2.1 to PX4 running on a Pixhawk 4. With the original setup, the retractable LG is on channel 7, and it works fine. Although I changed both the flight controller and firmware, the hardware setup is the same. However after the conversion to PX4/Pixhawk 4, the retract function does not work. I used the AUX Passthrough channels setup. I’ve set various params but nothing I’ve tried solves the issue.
This is what I have now:
RC_MAP_AUX1 set to Channel 7
RC_MAP_GEAR_SW set to Channel 7
PWM_MAIN_MAX7 set to 1900
PWM_MAIN_Min7 set to 1100
PWM_MAIN_FAIL7 set to 1100
How can I debug this issue? Are there any other params that need to be set?
Thanks,
Joe
