I'm trying to connect two Arduino Unos with Bluetooth modules (HC-06 and HC-05). Does anyone know the steps required to do that?

I still haven't figured out:

  • How to pair the two Bluetooth devices, and;
  • How to pair each Bluetooth with each Arduino.

If you have any useful tutorials, please let me know.

There is a nice example for Arduino here.

Connecting 2 Arduinos by Bluetooth using a HC-05 and a HC-06: Pair, Bind, and Link

The Uno works the same way as the board in the example.
