/*Note: this code is a demo for how to using gprs shield to send sms message, dial a voice call and send a http request to the website, upload data to pachube.com by TCP connection, The microcontrollers Digital Pin 7 and hence allow unhindered communication with GPRS Shield using SoftSerial Library. IDE: Arduino 1.0 or later Replace the following items in the code: 1.Phone number, don't forget add the country code 2.Replace the Access Point Name 3. Replace the Pachube API Key with your personal ones assigned to your account at cosm.com */ #include <SoftwareSerial.h> #include <String.h> SoftwareSerial mySerial(7, 8); void setup() { mySerial.begin(19200); // the GPRS baud rate Serial.begin(19200); // the GPRS baud rate delay(500); } void loop() { //after start up the program, you can using terminal to connect the serial of gprs shield, //if you input 't' in the terminal, the program will execute SendTextMessage(), it will show how to send a sms message, //if input 'd' in the terminal, it will execute DialVoiceCall(), etc. if (Serial.available()) switch(Serial.read()) { case 't': SendTextMessage(); break; case 'd': DialVoiceCall(); break; case 'h': SubmitHttpRequest(); break; case 's': Send2Pachube(); break; } if (mySerial.available()) Serial.write(mySerial.read()); } ///SendTextMessage() ///this function is to send a sms message void SendTextMessage() { mySerial.print("AT+CMGF=1\r"); //Because we want to send the SMS in text mode delay(100); mySerial.println("AT + CMGS = \"+8613616761237\"");//send sms message, be careful need to add a country code before the cellphone number delay(100); mySerial.println("A test message!");//the content of the message delay(100); mySerial.println((char)26);//the ASCII code of the ctrl+z is 26 delay(100); mySerial.println(); } ///DialVoiceCall ///this function is to dial a voice call void DialVoiceCall() { mySerial.println("ATD+8613616761237;");//dial the number delay(100); mySerial.println(); } ///SubmitHttpRequest() ///this function is submit a http request ///attention:the time of delay is very important, it must be set enough void SubmitHttpRequest() { mySerial.println("AT+CSQ"); delay(100); ShowSerialData();// this code is to show the data from gprs shield, in order to easily see the process of how the gprs shield submit a http request, and the following is for this purpose too. mySerial.println("AT+CGATT?"); delay(100); ShowSerialData(); mySerial.println("AT+SAPBR=3,1,\"CONTYPE\",\"GPRS\"");//setting the SAPBR, the connection type is using gprs delay(1000); ShowSerialData(); mySerial.println("AT+SAPBR=3,1,\"APN\",\"CMNET\"");//setting the APN, the second need you fill in your local apn server delay(4000); ShowSerialData(); mySerial.println("AT+SAPBR=1,1");//setting the SAPBR, for detail you can refer to the AT command mamual delay(2000); ShowSerialData(); mySerial.println("AT+HTTPINIT"); //init the HTTP request delay(2000); ShowSerialData(); mySerial.println("AT+HTTPPARA=\"URL\",\"http://122.226.151.4:6543/DHT11data.ashx?c=20.1&h=45.5\"");// setting the httppara, the second parameter is the website you want to access delay(1000); ShowSerialData(); mySerial.println("AT+HTTPACTION=0");//submit the request delay(10000);//the delay is very important, the delay time is base on the return from the website, if the return datas are very large, the time required longer. //while(!mySerial.available()); ShowSerialData(); mySerial.println("AT+HTTPREAD");// read the data from the website you access delay(300); ShowSerialData(); mySerial.println(""); delay(100); } ///send2Pachube()/// ///this function is to send the sensor data to the pachube, you can see the new value in the pachube after execute this function/// void Send2Pachube() { mySerial.println("AT+CGATT?"); delay(1000); ShowSerialData(); mySerial.println("AT+CSTT=\"CMNET\"");//start task and setting the APN, delay(1000); ShowSerialData(); mySerial.println("AT+CIICR");//bring up wireless connection delay(3000); ShowSerialData(); mySerial.println("AT+CIFSR");//get local IP adress delay(2000); ShowSerialData(); mySerial.println("AT+CIPSPRT=0"); delay(3000); ShowSerialData(); mySerial.println("AT+CIPSTART=\"tcp\",\"api.cosm.com\",\"8081\"");//start up the connection delay(2000); ShowSerialData(); mySerial.println("AT+CIPSEND");//begin send data to remote server delay(4000); ShowSerialData(); String humidity = "1031";//these 4 line code are imitate the real sensor data, because the demo did't add other sensor, so using 4 string variable to replace.
