Same thing happen to me tonight. My grandson wants a pixracer into his Quad-copter. Pixracer still on the bench and has 3.4.4. installed. USB and Mission planer is working perfectly. I have tried connect a new Radio Telemetry module tonight. It starts normally but than is getting stuck during-“Getting Params 1”. I have never seen that before. But also I have never used that Radio model from Bang-good before. I will try tomorrow a radio which has been working with my Pixhawks. No OSD connected. I have tried Telemetry 1 and Telemetry 2 same result. I thought I should let you know that it will happen in some situation.
