Please help, I want to use my old china button phone as a gsm module, to test if it can accept AT command through the serial monitor i connected my old button phone to rx-tx and tx-rx of arduino ,and i change the serial pins as well but i was getting garbage output to the serial monitor i have tried to change the baud rate but still getting same results here is the code:
#include <SoftwareSerial.h>
SoftwareSerial mySerial(2,3);
void setup()
{
mySerial.begin(19200);
Serial.begin(19200);
}
void loop()
{
if (mySerial.available())
Serial.write(mySerial.read());
if (Serial.available())
mySerial.write(Serial.read());
}
Did you change the baud rate in serial monitor?
Yes i change the baud rate of the serial monitor to match the baud rate i put in the code
i connected my old button phone to rx-tx and tx-rx of arduino
I assume that the 'phone actually has a serial interface. That sounds unusual
Yeah it has an rx and tx pins on it circuitry

That's interesting. What make/model of 'phone is it ?
Its itel keypad phone
Model-it5600
I can't find any reference to a serial interface in the specifications for that 'phone that I have found. Can you please supply a reference ?
This picture shows the Rx and TX point on the phone
I can see no reference to a serial interface on that site
