* This is a simple sketch used to demenstrate and test node-to-node MySensor's communication.
|
|
* To use this sketch, assemble MySensors nodes - they need nothing more than a radio
|
|
* 1. Flash each node with the same sketch, open the console and type either 0 or 1 to the respective nodes to set thei ID
|
|
* 2. You only need to set the node id once, and restart the nodes
|
|
* 3. To being a ping-pong test, simply type T in the console for one of the nodes.
