RadioLib CC1101 Receive with Address Example
|
|
|
|
This example receives 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.
