Moitessier HAT - HELP! Did not work :(

[SkipperEarly]

Hello Mateusz,

have you installed the proper moitessier package from the tool section? Have you chosen the correct version for your kernel?

Check if communication works and enter the following command in a terminal: cat /dev/moitessier.spi
Do you receive any data?

Does your HAT have clear view to sky? GNSS might not work if you are in a building.

Regards,
Thomas

cat /dev/moitessier.spi - no reply system seems to hang.

Could all these problems be as GNSS service is sometimes disrupted ?
