0 Sats in use but still get the correct position? #25

Closed LeCommandeur closed 2 years ago

LeCommandeur commented 2 years ago

Hi,

When I use the application and connect to a GNSS device via bluetooth and an NTRIP server, I do get a latitude and a longitude that pretty much correspond to my current location, but the field "N Sats used TOTAL" displays 0 and the following fields related to the different constellations display "No data" for the number of satellites in view.

This is most likely a bug or else how would I get a position that is correct?

I provided a screenshot of the application. I'm using a Samsung Galaxy S20 FE with up to date Android version if that helps.

Hello, thanks for the issue report. Please collect a nmea log (in settings) and share with me, I'll try run it through the parser unit test.

Hello,

Here is the NMEA Log, I hope it helps!

Hello,

Just checked your nmea log and found that your device is not sending G*GSA sentences that are the source of n sats used stats. (it is only GSV so it is showing n sats in view only) If your device is a u-blox device, you can enable it in u-center.

Yes it worked, thank you.
