RadioLib Si443x Transmit Example
This example transmits packets using Si4432 FSK radio module.
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)
Other modules from Si443x/RFM2x family can also be used.
For default module settings, see the wiki page
https://github.com/jgromes/RadioLib/wiki/Default-configuration#si443xrfm2x
For full API reference, see the GitHub Pages
