I am facing a problem. I am using readytosky Xrotor micro 30A ESCs, min ppm =1000 and max ppm =2000, and u have changed it to bidirectional in blheli suite, the motor gives 3 beeps but doesn’t seem to give arming beep when connected to pixhawk channel 1, I am using QGC for arming and testing. What to do?
- Check the orientation of the connector (try to turn it upside down)
- Check the output signal of the pin1 on the pixhawk: QGC application menu bar -> widgets -> mavlink inspector -> servo_output_raw -> channel 1
- Verify your settings in blheli suite, share a screenshot
What firmware are you using in the pixhawk?
