Our ROV setup is containing BRF2838 BLDC, 4in1 blheli_s ESC (Racerstar ESC for FPV drones), pixhawk 1 (ardusub 4.0.3) etc.
- How to test a single motor from MP? We couldn’t really find a way.
- We have managed to test from QGC for a single motor, and it is spinning like 30 rpm and I don’t know why? Isn’t ESC compatible with Ardupilot or something about the firmware wrong? ESC firmware is blheli_s J_H_90_REV16_7, ESC firmware is flashed for bidirectional (1100, 1500, 1900), PWM parameters of ardupilot, min-max and protocol(DShot600) is compatible with the ESC.
Btw plugging off the ground wire doesn’t affect the spin at all which is strange.
