The drone make beep beep sounds from motors after powered and not arm for a while, how to cancel that sounds
With Blheli/Blheli 32 Firmware tool you can remove it.
@Gino_Nencioni So the beep signal is not coming from flight controller? But I power the esc and motor alone ,it didn’t make beep beep sound
seems like there is trouble with passthrough BlHeli_S passthrough
Changing parameter “Beacon Delay” in BLHeli configure tool will fix the need
