Using HC-08 bluetooth module with arduino I have an arduino mega 2560 and a recently purchased HC-08 module and the connection is as the following:
Arduino | HC-08
VCC - VCC
GND - GND
14TX3 - TXD
15TX3 - RXD
When I power up the arduino it shows that flashing light and I am able to see it on my android phone but would only reject the connection every time I tried to pair. Also I am not able to send or receive any data from it at all, here is my code:
#include &lt;SoftwareSerial.h&gt;

SoftwareSerial hc08(15,14) // RX pin, TX pin;

void setup(){
  //Initialize Serial Monitor
  Serial.begin(9600);
  Serial.println(&quot;ENTER AT Commands:&quot;);
  //Initialize Bluetooth Serial Port
  hc08.begin(9600);
}

void loop(){
  //Write data from HC08 to Serial Monitor
  if (hc08.available()){
    Serial.println(&quot;Reading from bluetooth&quot;);
    Serial.write(hc08.read());
  }
  
  //Write from Serial Monitor to HC08
  if (Serial.available()){
    Serial.println(&quot;Writing to bluetooth&quot;);
    hc08.write(Serial.read());
  }  
}

I'd really appreciate help on how to get it working.
void setup(){
  //Initialize Serial Monitor
  Serial.begin(9600);
  Serial.println(&quot;ENTER AT Commands:&quot;);
  //Initialize Bluetooth Serial Port
  Serial3.begin(9600);
}

void loop(){
  //Write data from HC08 to Serial Monitor
  if (Serial3.available()){
    Serial.println(&quot;Reading from bluetooth&quot;);
    Serial.write(Serial3.read());
  }
  
  //Write from Serial Monitor to HC08
  if (Serial.available()){
    Serial.println(&quot;Writing to bluetooth&quot;);
    Serial3.write(Serial.read());
  }  
}
