GPS module PMB-248 help

Feijojr

Hello,


I received a GPS module and installed it in a BS2 P3.
I´m trying to get readings from it, and all that I get is a sequence of "6". Since the module do have an RX pin, I don´t know if some command must be sent prior to read Tx bytes. I did not find information on Parallax website. If somebody can help, it will be appreciated.

thanks.

the code I´m using:

'{$STAMP BS2}

'Program to read in GPS coordinates from the NMEA 0183 GPRMC statement
gpstime VAR Word
N VAR Word
W VAR Word
NN VAR Word
WW VAR Word
speed1 VAR Word
speed2 VAR Nib
course1 VAR Word
course2 VAR Nib
