Abnormal altitude jump problem

Hi, Menion.

We recorded track with outer bluetooth gnss receiver.

with setting mock location. It often occurs that altitude jumps abnormally.

I don't know why this happened. Other app recorded normal track at the same time.

I attached screenshot and track log.

Check it out please.

Abnormal altitude value comes in for 1~2 minutes.

Hello,

really nice. Does it happen for the first time? In case you use external BT GPS, best should be to enable recording of NMEA files (in Locus Map > settings > GPS & sensors > Record NMEA". With this setting, app will record all received information from BT GPS into files stored in Locus/data/nmea directory. So next time it happens, you may send me NMEA message(s) from that day and I may try to find and simulate the same issue on my own device. Otherwise, I'm unable to do anything with it. Thanks for understanding.

Menion
