Pixhawk4 wont calibrate senors

#1

Hi,

New to pixhawk4. I’m not sure if I’ve bricked it because I could calibrate sensors before, but now I cant in QGC. The latest firmware says its uploaded and LED lights are as follows:

I/O - PWR is solid green, B/E is fast red flashing, ACT is blue flash slow
FMU - ACT is blue flash slow, B/E no light, PWR solid green

Any guidance would be much appreciated.
