RadioLib RF69 Transmit to Address Example
|
|
|
|
This example transmits packets using RF69 FSK radio module.
|
|
Packets can have 1-byte address of the destination node.
|
|
After setting node (or broadcast) address, this node will
|
|
automatically filter out any packets that do not contain
|
|
either node address or broadcast address.
|
|
|
|
For full API reference, see the GitHub Pages
