Usage

[Case one]: GPRS Connectivity

SIM808 is a GPRS/GSM+ GPS Quad-band module, with this board, user can create IOT project such as data acquisition, remote controlling, GPS tracker and so on. The following simple application is use it as GPS tracker, to get your current location information. You can post your location information to the Google Maps then draw your trip.
1.Insert a Micro SIM card
The SIM808 GPS Tracker board uses the micro SIM card that is widely used in Android phone, install the Micro SIM card to the holder as below picture.
SIM808 GPS Tracker 3.JPG
Note that some fee maybe needed for each SMS depends on your local GSM Operator, make sure that the SIM Card is active and enough money left for this application.
2.Connect the GSM Antenna and the 3.7V battery
SIM808 GPS Tracker 4.JPG
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);
     delay(10000);
     sendData("AT+CIPSEND=6",1000,DEBUG);
     sendData("123456",1000,DEBUG);
     delay(2000);
     sendData("AT+CIPCLOSE",1000,DEBUG); 

Select the right port and Arduino board: Arduino pro mini 3.3V 8MHz to upload the firmware to SIM808 GPS Tracker boards SIM808 GPS Tracker 5.JPG
4.Test Result
If the GPRS service accessible, the Maduino board get data from the site, you can check the serial output debug info as:
SIM808 GPS Tracker 6.JPG
As shown on the above picture, the SIM808 GPS tracker has connect to the www.sim.com 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:
SIM808 GPS Tracker 6.JPG
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: SIM808 GPS Tracker 8.JPG

GPRS Connectivity

The Maduino GPRS GPS A7 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 an website):

     sendData("AT+CCID",3000,DEBUG); 
     sendData("AT+CREG?",3000,DEBUG);     
     sendData("AT+CGATT=1",1000,DEBUG);
     sendData("AT+CGDCONT=1,\"IP\",\"CMNET\"",1000,DEBUG);
     sendData("AT+CGACT=1,1",1000,DEBUG);
     sendData("AT+CIPSTART=\"TCP\",\"gtech.co\",80",3000,DEBUG);
     sendData("AT+CIPSEND=80",1000,DEBUG);
     sendData("GET http://gtech.co/gtech.php?hello HTTP/1.0\r\n HOST:gtech.co\r\n\r\n",100,DEBUG);
     delay(10000);
     sendData("AT+CIPCLOSE ",1000,DEBUG);

[Case two]: GPRS Connectivity

Of course the Maduino GPRS A6 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 an website):

     sendData("AT+CCID",3000,DEBUG); 
     sendData("AT+CREG?",3000,DEBUG);     
     sendData("AT+CGATT=1",1000,DEBUG);
     sendData("AT+CGDCONT=1,\"IP\",\"CMNET\"",1000,DEBUG);
     sendData("AT+CGACT=1,1",1000,DEBUG);
     sendData("AT+CIPSTART=\"TCP\",\"gtech.co\",80",3000,DEBUG);
     sendData("AT+CIPSEND=80",1000,DEBUG);
     sendData("GET http://gtech.co/gtech.php?hello HTTP/1.0\r\n HOST:gtech.co\r\n\r\n",100,DEBUG);
     delay(10000);
     sendData("AT+CIPCLOSE ",1000,DEBUG);

If the GPRS service accessible, the Maduino board get data from the site, you can check the serial output debug info as:
Maduino GPRS A6 12.JPG
Then you can upload/download related data from the site to create remote data acquisition or remote controlling.
