RadioLib CC1101 Transmit with Interrupts Example
|
|
|
|
This example transmits packets using CC1101 FSK radio module.
|
|
Once a packet is transmitted, an interrupt is triggered.
|
|
Each packet contains up to 64 bytes of data, in the form of:
|
|
- Arduino String
|
|
- null-terminated char array (C-string)
|
|
- arbitrary binary data (byte array)
|
|
|
|
For full API reference, see the GitHub Pages
