Hi, maybe you can check GPS as these steps.

  1. Downdload the Arduino IDE for RePhone( seeedstudio.com/wiki/Arduino … ePhone_Kit );
  2. Select MTK USB Debug Port ,upload the GPS test code, …\Arduino_IDE_for_RePhone\hardware\arduino\mtk\libraries\LGPS\examples\gps_test;
  3. Switch the selected COM Port to MTK USB Modem Port and open the Serial Monitor;
  4. When have been located, these information will output. But if haven’t been located it also output information about a running UTC time.
