I have been looking on Google for a project that involves 2 Arduinos communicating with Bluetooth. The only examples I can find are with an Arduino to an Android phone.

Does anyone have links to let me know how I would go about hooking two Arduinos up to Bluetooth?

The Bluetooth module I'm using is the Bluetooth RF Transceiver Module Card RS232 TTL (i guess better known as the HC-05). Here is an ebay link.

  • \$\begingroup\$ When you say "communicating" what exactly are the 2 Arduinos going to share? If it is serial data, RX/TX to TX/RX on the BT; each. Then Serial.read() and Serial.write() to exchange data streams. To exchange pin outputs is a different story. \$\endgroup\$
