Pass through attachment

Hey guys,

I am having troubles with attachment of pass through of BlHeli32 version 8 with Cuav7 controller on ardupilot.

My BlHeli32 program connects to the flight controller but does not see the ESC’s. It gives some error and tells me to update the 4 way protocol, and I can’t find anywhere how to update it.

My parameters are:


SERVO_BLH_MASK=15 (I set it up for channels 1-4, without the mask it does not work as well)
Also I’m using DShot 300.

The copter works fine, it flies but that is the only thing that does not work.
