Using a nook for xcsoar

I know it would not have the vario information but would it be as accurate as a standalone Dell Streak say?


The problem with the CAI 10/20/25 is that they don't provide an NMEA
sentence that contains GPS altitude, and the most common firmware
versions only output pressure altitude if you send them a special
handshake sequence which (to my knowledge) has not been revealed to
3rd parties. So, you could see your position on the Nook, but you'd
likely be out of luck on altitude...

My experience is, that CAI and Volkslogger GPS signals are quite a
lot delayed. Might be slow communication speed, or filtering. This
makes it difficult to use moving map for navigation. FLARM works
much better.
