Pixhawk 6x Dev Kit - ESCs not detecting signal and beep repeatedly

ArduCopter Copter 4.6

Hi All,

This is my first build, and I’ve run into a roadblock I can’t seem to figure out. I have tested the ESCs on receiver pins and they all work, and I’ve confirmed with a multimeter that the 5v rail on the rear pins are powered from the BEC. I’ve tried moving through MOT_PWM_TYPE with Dshot300 and 600, then down to regular analog (0) and Oneshot125 (2). on analog and oneshot I tried to calibrate the ESCs, but when I power back up from the battery, the esc/motors just keep beeping at me (even after I press the red light/buzzer button on the GPS and it goes solid. I have my FRSKY X18 calibrated in radio calibration, and I’ve tried to adjust the trim above and below max on throttle before calibrating to make sure it’s sending a nice, strong max signal.

After a while of looking on here, Googling, and working with AI to troubleshoot, I’m stuck. I’ve given some information and my parameter configuration below and would greatly appreciate any help. Thanks in advance :slight_smile:

Frame: Holybro x600
FC: Pixhawk 6X
ESC: Tekko32 F4 45A ESC with XT30 Plugs
Radio: Frsky TD x18 (Archer Plus R6 receiver in ACCESS mode)
Motors: Tmotor MN4014 KV330 Motor with XT30 Plug
Batt: 8000mah 26c 6S

…updated parameter config file. I’m trying to use dshot600, and I can get the system to arm, and the pixhawk seems to beep like it’s trying to send signal to the ESCs, but the motors keep beeping and never spin up, even when I set the min motor output to like 20%.

It’s misconfigured all the way around. Go here and make an attempt to correct it:
Dshot ESC’s
Do you have the Bdshot firmware flashed to the Pixhawk? If so configure for Bdshot.

oh my goodness - all I had to do was enable BRD_IO_DSHOT, reboot, and the motors fired right up! I’m so excited to see the motors fire up!! Thank you so much for pointing me in the right direction.
