+xWell, bear in mind that we have not managed to see any invalid data from the TRX device we are currently testing.
Did you test it on Android or iOS?
Maybe...I don't know the difference between TRX and original FLARM. Maybe differences in data protocol? Don't know.
I just know, that there are issues with Andoid devices (i have tested 4 defferent ones) and no issues with iOS.
You mentioned, that SD does not accept any errors from GPS devices, so the FLARM has to be ok. Why else should
the FLARM on iOS working flawlessly? (Tested 24h)
Pleas help and let me love SD again. It is one of the best navigation apps i know.
