I'm unable to download logs from IRIS. When I connect to it in MissionPlanner terminal it keeps outputting strange characters every second. First it prints standard
Ready to FLY ublox OK
then it prints strange characters like
QMQH3Qv... and so on, endless sequence, there is also PreArm: INS not healthy text from time to time.
What can be the reason? Other than terminal issue the IRIS works just fine.
