Hello Morco,
Thanks a lot for your testing and these great remarks!!Unfortunately I still don't have it working yet... The reason I couldn't get back earlier being some other obligations..
Your checksum observation is super interesting. Indeed, it seems like "GPS over BT" app somehow only transferred single digit checksums in all my registered nmea protocols. Also the weird date is very strange. I have checked, and could not find the source for this error. In all device, app and program settings of both laptop and android device, the correct date was being used. On the other hand, I don't know it if this should really impact position/GPS fix, since it is sent in a different NMEA phrase?
So as I have already mentioned in the EDIT note of my last post, I have tried a different app, "ShareGPS", and here, all of a sudden, the NMEA phrases arriving at the computer's com port are perfectly readable for VisualGPSView. I get all the position data and satellite plots. I have checked the phrases and they look a lot different from the phrases sent by the previous app "GPS over BT". The phrases sent by "ShareGPS" have dual-digit checksums. "ShareGPS" does not send any $GPZDA string, hence no date that I could check.
Here you can find the example files I registered, where position is perfectly displayed: [Only registered and activated users can see links. ]
Big bummer was, that when checking in AMIDuOS, nothing changed at all. The com port is being read (The "ShareGPS" status on the android device switches to "Connected" and the com port is blocked for other windows programs) but no location is available within AMIDuOS. All the "GPS test" app says "No Fix" and location 0.000N, 0.000E. Same for all other apps inside AMIDuOS.
Not sure, where the problem is. Have you, btw, activated "mock location" in AMIDuOS developer options settings?
Anyway. I might be able to test some more tomorrow. Maybe using a different device to send the GPS data to the com port. The first quick tests I have conducted in that direction haven't changed anything, though.
Tuesday, I will finally have access to the real field equipment, Trimble tablet and antenna and I'll just try the same thing there. Maybe my computer is just lacking willingness.
Last resort will be writing a custom bridge between Windows and an emulator + using this app, which a programming expert friend of mine discovered: [Only registered and activated users can see links. ]
I'll keep you updated on the progress. Have a nice evening!![]()
