How much of this is open source? And does it use any existing open standards? For instance, is the bluetooth GPS data communicated via some standard protocol/format so that it can be expected to work with non-Nokia GPS devices? -- Murray Cumming [EMAIL PROTECTED] www.murrayc.com www.openismus.com
As far as I can see, it is just an organised way to spawn gpsd ( http://gpsd.berlios.de/) , and connect it to a bluetooth GPS receiver over rfcomm. gpsd then gives you a socket interface with a normalised ASCII string of position info, or you can get the NMEA stream and decode it yourself.
