What does that mean? Never come across this before. This is the latest 3.5.0-rc5 on a Pixhawk 2.1 cube. Other 2.1's are work fine, but they're running 3.5.0-rc4.
Turns out the calibration is failing over the modems. Once calibrated with a usb cable, the message clears.
So I'm getting this error. I'm doing all my setup by USB. Any suggestions. I did calibration on all mandatory items.
