BlHeli32 problems

Hi guys.
Setup is Pixhawk cube 2.1
ESC T-mtor 45A 32 bit.

I’m having problems with runing reading confing on BLheli suite 32.

I wanted to change my ESC protocol on pixhawk from “normal” to “dshot150”.

Changed all parameters in arupilot to make ESC work on DShot150, then disconnected from ardupilot (im using only usb connection) and i ran BlHeli32suite. I’ve connected to blheli and i can’t read setup from ESCs…

All ESC were connected via main output 1,2,3,4.

I’ve plug them to AUX 1,2,3,4 and changed SERVOs output to set motors on aux 1,2,3,4 and… i only get parameters from ESC 1,2,3… why…

help pls.

Did you got any solution on this?
