Question for N810 users that has been asked in the past but not directly answered:

Does the 'gpsbt' GPS mode on your devices use (successfully) the 'built-in' GPS devices inside your tablets?

I have a user of 'MChronos' that experiences a 'reset' whenever he tries to use this program for a GPS reading with the 'gpsbt' mode.

This question would also apply to the 'MEphemeris' program.
