// Simple example of how to use VirtualWire to send and receive messages
|
||
|
|
// with a DR3100 module.
|
||
|
|
// Send a message to another arduino running the 'server' example, which
|
||
|
|
// should send a reply, which we will check
|
||
|
|
//
|
||
|
|
// See VirtualWire.h for detailed API docs
