Hi, I am a beginner with Arduino, I am trying the same thing and I am having the same problem, when I type the AT commands, I get no response, so I have change a part of code to understand what was going wrong.
if (Serial.available()>0) {
char x = (char)Serial.read();
switch (x) {
case '1':
Serial.println("Opcao 1:");
BTSerial.print("AT+VERSION?\r\n");
break;
case '2':
Serial.println("Opcao 2:");
BTSerial.print("AT+PSWD?\r\n");
break;
case '3':
Serial.println("Opcao 3:");
BTSerial.print("AT+ADDR?\r\n");
break;
case '4':
BTSerial.print("AT+NAME?\r\n");
break;
case '5':
BTSerial.print("AT+IAC?\r\n");
break;
case '6':
BTSerial.print("AT+INQM?\r\n");
break;
case '7':
BTSerial.print("AT+UART?\r\n");
break;
default:
BTSerial.println(Serial.read());
}
}
All the commands worked fine EXCEPT the one in default, there must be some kind of problem in the Serial.read() return format. Anyone knows??
