I am trying to receive a confirmation code from T-Mobile to set up my online account for this Pay-As-You-Go sim card. I am using an Arduino Uno R3 and Seeedstudios GPRS Shield V1.0 with the SIM900 module.
Current code below.
Here is what I am seeing in terminal after I sent a text message out and then went and requested a confirmation code from T-mobile's website:
#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()
{
if (Serial.available())
switch(Serial.read())
{
case 't':
SendTextMessage();
break;
case 'd':
DialVoiceCall();
break;
}
if (mySerial.available())
Serial.write(mySerial.read());
}
///SendTextMessage
void SendTextMessage()
{
mySerial.print("AT+CMGF=1\r"); //Because we want to send the SMS in text mode
delay(100);
mySerial.println("AT + CMGS = \"+12138882702\"");//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
void DialVoiceCall()
{
mySerial.println("ATD + +86138xxxxx615;");//dial the number
delay(100);
mySerial.println();
}
void ShowSerialData()
{
while(mySerial.available()!=0)
Serial.write(mySerial.read());
}
