HC-05

Using Arduino Programming Questions
1

I have paired two hc-05 Bluetooth using AT command mode. I can not find at all any code for sending info back and forth between them. All I can find is how to pair them. Can you help me find a source code. It would be much appreciated.

I blew up one of my HC-05 modules while playing for the first time with them :frowning:

But it should be a matter of using standard serial methods like read and print (as far as I understand it). Assuming you use software serial

sketch one (transmitter)

void loop()
{
  if(Serial.available())
  {
    // get data from PC and send over bluetooth
    swSerial.print(Serial.read());
  }
}

sketch 2 (receiver)

void loop()
{
  if(swSerial.available())
  {
    // get data from bluetooth and send to PC
    Serial.print(swSerial.read());
  }
}

Use two terminal programs (or two instances of the IDE and their respective serial monitors), hook up bth Arduinos and test.

Take them both out of command mode.

Write some stuff to one of them using software serial write.

After a few milliseconds, the stuff that you wrote should be available on the other using software serial read.

thanks i will try these suggestions
