I have gps sirf 3 " CTFGPS-2 USB GPS Receiver " (http://www.cartft.com/catalog/il/649), it worked ok, but surfing all sirfdemo menus,I don`t know what I did but it doesn't work now. Gps Red Led Turned off, and I don't know what can I do ....
Can you help me? How can I reset the gps? Thanks a lot
Using the Sirf3-engineer program is dangerous. You easily can destroy the GPS receiver with it.
You should try doing a factory reset and set mode to NMEA again.
