Hi,
The bluetooth Dongle should create a 'virtual Serial Port' in your
Sony Ericsson, over which the Bluetooth GPS that you will buy will
stream data in NMEA format (simple ASCII strings containing RMS, GGA
'sentences', containing the GPS long/lat, speed, course data etc.)
technically this is called serial port emulation. "Serial Port
Profile (SPP) allows Bluetooth devices to perform RS232 (or similar)
serial cable emulation"
So effectively, you should use the Serial port Access API provided in
the J2ME compiler to recieve the strings, parse them (there are APIs
for that also), and log/show the coordinates in your custom
application.
