Hi all!
I've tried many things to make serial communication with SonyEricsson c902 and no luck . There are some posts on this forum regarding serial comm with SE phones but it did not work for me. The difference from my phone and one used in previous discussion is that my phone has new system connector.
I have searched for system connector explanation and according to it, I should make a wiring the following way:
SE Arduino
Pin 9 (GND) --------------------> GND
Pin 10 (RX) --------------------> TX
Pin 11 (TX) --------------------> RX
Is this correct? I'm I missing something?
The code running on Arduino is the following:
void setup()
{
Serial.begin(9600);
}
void loop()
{
// wait x seconds before sending a new command
delay(5000);
Serial.println("ATD000"); // AT command for calling number 000
}
Does anyone knows what am I doing wrong?
Thanks in forehand
Cheers....
