RadioLib AX.25 Transmit Example
This example sends AX.25 messages using
SX1278's FSK modem.
Other modules that can be used for AX.25:
- SX127x/RFM9x
- RF69
- SX1231
- CC1101
- SX126x
- nRF24
- Si443x/RFM2x
For default module settings, see the wiki page
https://github.com/jgromes/RadioLib/wiki/Default-configuration
For full API reference, see the GitHub Pages
