2. Connect the GSM Antenna and the 3.7V battery
3. Programming and download
The SIM808 GPS Tracker can be capable of the GPRS connectivity for Internet, to
upload/download data with internet. The following simple example shows the starters
how to access a website on the internet (Users need check the AT commands for how to
access a website): (Demo Code Download)
sendData("AT+CCID",3000,DEBUG);
sendData("AT+CREG?",3000,DEBUG);
sendData("AT+CGATT=1",1000,DEBUG);
sendData("AT+CGACT=1,1",1000,DEBUG);
sendData("AT+CSTT=CMNET",3000,DEBUG);
sendData("AT+CIICR",1000,DEBUG);
sendData("AT+CIFSR",1000,DEBUG);
sendData("AT+CDNSGIP=\"www.sim.com\"",1000,DEBUG);
sendData("AT+CDNSGIP=\"a b c d e f\"",1000,DEBUG);
sendData("AT+CIPSTART=\"TCP\",\"WWW.SIM.COM\",80",5000,DEBUG);
