Basic Tips :

TX(transmitter) pin usually connect RX pin.

RX(receiver) pin usually connect TX pin

When upload coding to Arduino board, you cannot connect the TX & RX pin to bluetooth module.

Remove the wiring 1st before upload coding, after done upload. Then only connect the wiring.

5V = VCC

GND =GND

2 = TX

3 = RX

EN = 5V(Enable AT MODE)(For HC05 Model only)

BASIC AT COMMAND :

AT+NAME? (Function : check name)

AT+NAME=SAMPLE (Function : set name to SAMPLE)

AT+ADDR? (Function : check default address)

AT+PSWD? (Function : check default password)

Test Code Sample :

#include <SoftwareSerial.h>

SoftwareSerial mySerial (2,3);

void setup () {

mySerial.begin(9600);

Serial.begin(9600);

Serial.println("Enter AT commands:");

}

void loop() {

while (mySerial.available()) {

Serial.write(mySerial.read());

}

while (Serial.available()) {

mySerial.write(Serial.read());

}

}
