I need help!
I want to send an SMS with a Sony Ericsson T230, but do not know source code.
I just know how to make connections between Arduino and telephone.
I want to send a sms from Arduino, the number 12345678 with the text "I sent an SMS with the Arduino.
Arduino sending AT commands to Sony Ericsson T230 are the next link www.engineersgarage.com/tutorials/at-commands
Thank you very much for your help!
What have you tried?
It looks like the CMGW command is used to store a message to be sent, and the CMGS command is used to send the message.
Are you able to get an "OK" response from the phone?
I do not know which cable I need? and I do not know how to send OK, that answer the phone?
I saw someone on youtube with a phone that's like my T230, which calls for the Arduino and not use than some cables stuck back on the phone!
site is next: - YouTube
I just know how to make connections between Arduino and telephone.
So, what connections have YOU made?
If you are connecting the phone to the serial port on the Arduino, you can talk to it using Serial.print().
I've made ??connections in the movie! but do not know how to send SMS. which is actually the source code! serial.print (....), here do not know what to write!
Look at the link in your initial post. It tells you what to send to the phone to make it do things. Send the AT command by itself, using:
Serial.print("AT");
delay(1000);
Put this in setup(), after the Serial.begin() statement.
In loop(), put:
while(Serial.available() > 0)
{
char letter = Serial.read();
digitalWrite(13, HIGH);
delay(250);
digitalWrite(13, LOW);
delay(100);
}
If the LED on the Arduino flashes, the phone responded. The number of times it flashes corresponds to the number of characters returned.
I've made ??connections in the movie!
Pretty hard to tell from that movie what is connected where on the phone.
I saw someone on youtube with a phone that's like my T230, which calls for the Arduino and not use than some cables stuck back on the phone!
There may be something lost in translation here, but "a phone like my T230" and "the same phone I have" are sufficiently different that what works on their phone may not work on yours.
Show how YOU connected YOUR phone, better than in the video, and post the code you are using. Only then can we provide any real help.
I made ??connections, as in this picture
source code is:
#include <NewSoftSerial.h>
const int PIN_RX = 8;
const int PIN_TX = 10;
NewSoftSerial com(PIN_RX, PIN_TX);
void setup()
{
com.begin(9600);
}
void loop()
{
com.println("AT+CMSS=5,'0760151558'");
delay(3000);
}
my problem is I can not send sms! I do not know what to write in loop ()
You won't be able to send SMS until you get the Arduino to talk to the phone. Get over it.
In setup(), use com.print("AT"); to send the AT command to the phone.
In loop(), use com.available() to see if there is data to read (a response from the phone). If there is, use com.read() to read a byte, and Serial.print() to send that character to the serial port so it can be seen in the Serial Monitor. Don't forget the Serial.begin() statement in setup().
When you know that the Arduino can talk to the phone, you can send the actual command(s) to send an SMS (most likely using com.print(), not com.println()).
but the source code would be?
Hi Fierry
It can be a bit tricky to get the communication to work with the phone.
I have a little project, where i'm using a SonyEricsson z600 to sen SMS'es, using the library found here: Google Code Archive - Long-term storage for Google Code Project Hosting.
However... it is important that you are sure that you have a serial connection to your phone from your arduino, before you jump into all the programming.
If you have Bluetooth on your PC, i recommend connecting to the phone via a virtual com port. That way you can use hyperterminal (or other terminal software) to talk to the phone, and try and use the AT command set. Try to manually write commands to the phone, and make it send a SMS.
It is important to figure out if the phone supports SMS in TXT mode, or in PDU mode. The latter would be quite difficult to handle in the arduino program.
Once you figure out those things, you can move on, and connect the phone to the arduino (your connections look right, by the way! 
), and see if you can get an AT command through from you PC terminal program, through the arduino, to the phone. the reply to 'AT' should be 'OK'
Good luck
#include <NewSoftSerial.h>
const int PIN_RX = 8;
const int PIN_TX = 10;
NewSoftSerial com(PIN_RX, PIN_TX);
void setup()
{
Serial.begin(9600);
delay(500);
com.begin(9600);
delay(500);
com.print("AT");
}
void loop()
{
if(com.available() > 0)
{
Serial.print(com.read(), BYTE);
}
}
You really are going to need to learn to do this on your own.
