RadioLib CC1101 Transmit to Address Example
|
|
|
|
This example transmits packets using CC1101 FSK radio
|
|
module. Packets can have 1-byte address of the
|
|
destination node. After setting node address, this node
|
|
will automatically filter out any packets that do not
|
|
contain either node address or broadcast addresses.
|
|
|
|
For default module settings, see the wiki page
|
|
https://github.com/jgromes/RadioLib/wiki/Default-configuration#cc1101
|
|
|
|
For full API reference, see the GitHub Pages
