(/wiki/index.php/File:TEL0097_pin_mapping.png) SIM808 GPS/GPRS/GSM Shield Module interface and precautions: 1. Occupied pins: D0, D1, D12, the digital pin "D12" is connected to SIM808 module power GPIO. It can be used as SIM808 module on / off control. 2. SIM808 onboard MIC and 3.5mm SIM808 microphone are using the same MIC channel, when you plugin your microphone, the onboard MIC will be automatically disconnected. 3.

4. Set the function switch to `None` 5. Upload the sample code 6. Set the function switch to `Arduino` and make sure SIM808 could communicate with Arduino board 7. Press the Boot power button 8. Wait for the SIM card to register the network, the Net indicator LED will slowly flash every 3 seconds Examples Make Phone Calls This example tests DFRobot_SIM808 SIM808 GPS/GPRS/GSM Shield's callUp function. 1. Open the SIM808_CallUp example or copy the following code to your IDE 2.

This example tests the DFRobot_SIM808 GPS/GPRS/GSM Shield's call answering and SMS reading function. 1. Open the `SIM808_LoopHandle` example or copy the code to your project 2. Download and set the function switch to `Arduino` 3. The shield will autoanswer phone calls or send SMS Messages to the serial terminal #include #define MESSAGE_LENGTH 20 char gprsBuffer[64]; char *s = NULL; DFRobot_SIM808 sim808(&Serial); void setup() { //mySerial.begin(9600); Serial.

3. Press the Boot power button and wait for the SIM card registering a network properly, the Net indicator led flashes slowly (3s once). 4. Slide the function switch to USB_DBG, then we can communicate directly with SIM808 chip through the serial port assistant. Make a Phone Call (/wiki/index.php/File:TEL0097_Phone_call.png) Make a Phone Call Send AT in the serial port assistant, if it returns OK, it means that serial communication has been established.

(/wiki/index.php/File:TEL0097_TCP.png) TCP communication GPS Orientation Note: The GPS antenna must be placed outside before it can obtain a stable GPS location data output. Send AT + CGSN PWR = 1 command (Open the GPS power) Send AT + CGNSTST = 1 command (Receive GPS data from the serial port) (/wiki/index.php/File:TEL0097_GPS_debug.jpg) GPS_debug If the GPS antenna has been placed outside, you should get the right data soon.

If you are going to use SIM808 GPS/GPRS/GSM Shield with a Leonardo board, it will be more like a SIM808 GPS/GPRS/GSM mainboard . You can check its wiki for the user manual.
