Hi.I am trying to send sms using Arduino GSM Shield with Arduino Uno r3.The code uploaded is:
// Include the GSM library
#include <GSM.h>
#define PINNUMBER "1234"
// initialize the library instance
GSM gsmAccess(true);
GSM_SMS sms;
void setup()
{
// initialize serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
Serial.println("SMS Messages Sender");
// connection state
boolean notConnected = true;
// Start GSM shield
// If your SIM has PIN, pass it as a parameter of begin() in quotes
while(notConnected)
{
if(gsmAccess.begin(PINNUMBER)==GSM_READY)
notConnected = false;
else
{
Serial.println("Not connected");
delay(1000);
}
}
Serial.println("GSM initialized");
}
void loop()
{
Serial.print("Enter a mobile number: ");
char remoteNum[20]; // telephone number to send sms
readSerial(remoteNum);
Serial.println(remoteNum);
// sms text
Serial.print("Now, enter SMS content: ");
char txtMsg[200];
readSerial(txtMsg);
Serial.println("SENDING");
Serial.println();
Serial.println("Message:");
Serial.println(txtMsg);
// send the message
sms.beginSMS(remoteNum);
sms.print(txtMsg);
sms.endSMS();
Serial.println("\nCOMPLETE!\n");
}
/*
Read input serial
*/
int readSerial(char result[])
{
int i = 0;
while(1)
{
while (Serial.available() > 0)
{
char inChar = Serial.read();
if (inChar == '\n')
{
result = '\0';
- Serial.flush();*
- return 0;*
- }*
- if(inChar!='\r')*
- {*
_ result = inChar;_
* i++;*
* }*
* }*
* }*
}
..and the serial monitor output is:
SMS Messages Sender
AT%13%
0 9>AT%13%%13%%10%OK%13%%10%
AT+CPIN=1234%13%
9 44>AT+CPIN=1234%13%%13%%10%+CPIN: READY%13%%10%%13%%10%OK%13%%10%
AT+CGREG?%13%
44 75>AT+CGREG?%13%%13%%10%+CGREG: 0,2%13%%10%%13%%10%OK%13%%10%
AT+CGREG?%13%
89 120>AT+CGREG?%13%%13%%10%+CGREG: 0,2%13%%10%%13%%10%OK%13%%10%
AT+CGREG?%13%
120 23>AT+CGREG?%13%%13%%10%+CGREG: 0,2%13%%10%%13%%10%OK%13%%10%
AT+CGREG?%13%
but suddenly stop write output code and switch off the NET and the STATUS led on Arduino.
I have read that the meaning of CGREG: 0,2% is waiting for connecting .¿Could be about the code?
Thank you very much.
