Hello

I have a drone with 2 Here 4 GNSS modules connected to a orange cube + on a kore board.

My parameters are like this:

The modules get recognised, see here:

I could also make a firmware update, but it only shows on startup for a couple of seconds some satellites and after that only no GPS fix for both units.

I have a similiar drone also with 2 here 4 units and used the same settings, so I´m not sure, why I have this problem here.

I’m grateful for every tip.

Just to make sure. Are you in a clear area with no obstacles surrounding?
