In this video, we implement the function that when the FC receives the PID gain request messages from the GCS, the FC responds with the GCS with the corresponding gains according to the requested gain ID.

M-HIVE "STM32 Drone programming from scratch"
This is the only course about the drone embedded system development from sensor interface, the most basic feature, to PID control for the flight control.
