Hello.
I'd like to give a AT command to a HC-06 bluetooth module using the Arduino due.
I connect lines as below.
Arduino DUE HC-06
5v > Vcc
GND > GND
TX1 > RX
RX1 > TX
And i upload this code to due board. but the HC-06 bluetooth module has no reaction to AT command.
I don't know what's the cause of this.
Please help me. Thank you.
void setup() {
Serial.begin(9600);
Serial1.begin(9600);
}
void loop() {
if(Serial.available())
Serial1.write(Serial.read());
if(Serial1.available())
Serial.write(Serial1.read());
}
I understand a Due is a 3.3v Mega, so try this.
/*
This is for MEGA
It seems internally HC-06 only responds to 9600 anyhow.
Even if you set the baud rate to 115200 you can "reprogram"
the sketch again with 9600.
JY-MCU board pins
RX - 18 Tx1 orange
TX - 19 Rx1 white
GND - GND black
VCC - 5v red
Kudos to marguskohv - he sowed the seed....
Serial monitor is just aide memoire
*/
String command = ""; // Stores response from HC-06
void setup() {
// put your setup code here, to run once:
Serial.begin(9600); //monitor
Serial1.begin(9600); //bluetooth
Serial.println("AT");
Serial1.print("AT"); //PING
if (Serial1.available()) {
while(Serial1.available()) { // While there is more to be read, keep reading.
delay(3);
char c = Serial1.read();
command += c;
}
}
delay(2000);
Serial.println(command);
command = ""; // No repeats
Serial.println("AT+NAMEFosters");
Serial1.print("AT+NAMEFosters"); //CHANGE NAME
if (Serial1.available()) {
while(Serial1.available()) { // While there is more to be read, keep reading.
delay(3);
command += (char)Serial1.read();
}
}
delay(2000);
Serial.println(command);
command = ""; // No repeats
Serial.println("AT+PIN1234");
Serial1.print("AT+PIN1234"); //CHANGE PASSWORD
if (Serial1.available()) {
while(Serial1.available()) { // While there is more to be read, keep reading.
delay(3);
command += (char)Serial1.read();
}
}
delay(2000);
Serial.println(command);
command = ""; // No repeats
Serial.println("AT+BAUD8");
Serial1.print("AT+BAUD8"); //CHANGE SPEED TO 115K
if (Serial1.available()) {
while(Serial1.available()) { // While there is more to be read, keep reading.
command += (char)Serial1.read();
delay(2000);
Serial.println(command);
}
}
}
void loop(){
} //one-shot - nothing here
Thank you.
I got a result like this. (attached image)
I must admit I never looked at the screen when I did it but I guess it gives you what you want. Just edit the programme to change the name, p/w, and/or baud rate to what you want.
