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 <DFRobot_sim808.h>

#define MESSAGE_LENGTH 20

char gprsBuffer[64];

char *s = NULL;

DFRobot_SIM808 sim808(&Serial);

void setup() {

//mySerial.begin(9600);

Serial.begin(9600);

//******** Initialize sim808 module *************

while(!sim808.init()) {

Serial.print("Sim808 init error\r\n");

delay(1000);

}

delay(3000);

Serial.println("Init Success, please call or send SMS message to me!");

}

void loop() {

//******** Wait serial data *************

if(sim808.readable()){

sim808_read_buffer(gprsBuffer,32,DEFAULT_TIMEOUT);

//Serial.print(gprsBuffer);

//************** Detect the current state of the telephone or SMS ************************

if(NULL != strstr(gprsBuffer,"RING")) {

sim808.answer();

}else if(NULL != (s = strstr(gprsBuffer,"+CMTI: \"SM\""))) { //SMS: $$+CMTI: "SM",24$$

char message[MESSAGE_LENGTH];

int messageIndex = atoi(s+12);

sim808.readSMS(messageIndex, message,MESSAGE_LENGTH);

Serial.print("Recv Message: ");

Serial.println(message);

}

sim808_clean_buffer(gprsBuffer,32);

}

Read SMS Messages

This example tests the DFRobot_SIM808 GPS/GPRS/GSM Shield's ability to read SMS messages.

1. Open the `SIM808_SMSread` example or copy the code to your project

2. Download and set the function switch to `Arduino`

3. The shield will receive SMS Messages and send them to the serial terminal
