Hi got a used Tarot 680 pro, checked soldering under top plate, looks fine, when i power up with my pixhawk and have all 6 DJI E600 connected to the DJI 3508 motors all ESCS are beeping like crazy at start up even if i press the safety button after bootup, only one ESC seems to do the tune that says its ready.
What can cause this, its setup with servo1 - Servo6 for motors and Hexa as frame model.
I tried to do a ESC calibration in GCS but only one esc seems to wanna do it.

Here you can see the issue
Those DJI ESCs don’t support calibration, you have to set the PWM range in params MOT_PWM_MIN and MOT_PWM_MAX
I only see hz on dji site, how do I find pwn rate for these
I believe it is
MOT_PWM_MIN,1120
MOT_PWM_MAX,1920
Be sure to use the MissionPlanner motor test to find and set
MOT_SPIN_ARM
MOT_SPIN_MIN
