First upload code into modules with programmer (e.g. CK-USB-04A).
IQRFxxteaExampleTX.c and IQRFxxteaExampleRX.c are examples of usage of the XXTEA algorithm:
- IQRFxxteaExampleTX.c - After pressing the button, the program encrypts the contents of bufferRF and sends the message wirelessly
- IQRFxxteaExampleRX.c - The program waits for the message to be received, then decrypts it and sends it over the serial link to the computer
