[gyzmo82]

Hi All,

getting "Waiting for GPS fix" error but as a matter of fact it seems there is a gps lock. There are plenty of satellites visible. In inav configurator the map is showing the precise place.

Please kindly help if someone faced this issue.

Thanks!

That can happen if you write INAV 7 or 8 over the top of INAV 6, but turn off the erase setting. That leaves a binary representation of the INAV 6 settings on the FC - which are not compatible with 7 or 8.

The specific setting you are running into here can be corrected with:

set inav_max_eph_epv = 1000
save

But it's suggested to follow the upgrade procedure listed on the download page and in the release notes.
