A few months ago i purchased a pair of Rockwell micro tracker GPS receivers from ebay.
It's only now that i've had chance to play with one...
I have wired up a MAX232 and all is functioning correctly.
I wired in a single LiPOL as battery backup for the GPS unit as recommended in the datasheet...
the datasheet says that first fix can take upto 15 mins from a complete power down so i left it connected to a USB to serial cable on my laptop with realterm running.
When i come to go bed the only thing in realterm was the standard 'hello' NMEA string that it left upon power up.
i left it over night and it still hasn't started spitting out NMEA strings...Code:$GPGGA,,,,,,0,00,,,,,,,*66 $GPGGA,,,,,,0,00,,,,,,,*66 $GPGGA,,,,,,0,00,,,,,,,*66 $GPGGA,,,,,,0,00,,,,,,,*66 $GPGGA,,,,,,0,00,,,,,,,*66
The antenna is sat on my window ledge i'm guessing it can't find enough satellites???
Unfortunately, the manual is crap, but does anyone know a way of getting it to tell me what it is doing?
Thanks
