and now you can upload/download the data. 
[Case two]: Get GPS Location 
The SIM808 GPS Tracker gets the GPS signal with UART interface, customers can stock 
the GPS info into the SD card, of send to the internet with the GPRS connectivity: 
GNSS power control 
void setgps(void) 
{ 
      sendData( "AT+CGNSPWR=1",1000,DEBUG);        //power GNSS 
      sendData( "AT+CGNSSEQ=RMC",1000,DEBUG); // define the last NMEA sentence 
that parsed 
} 
Get current Location information 
sendData( "AT+CGNSINF",1000,DEBUG);     
Then the SIM808 will report the related GPS into to Atmega328, with the UART interface, 
you can check the reported GPS info via the Atmega hardware interface:
