BastWAN LoRa RNG

A project demonstrating how to generate random numbers on the BastWAN / RAK4260 using LoRa.

In this version the LoRa-based RNG code is in the LoRandom.h header file, and can be used anywhere. To use the LoRandom.h library in your code, you need to provide 2 functions:

void writeRegister(uint8_t reg, uint8_t value);
uint8_t readRegister(uint8_t reg);

You need to call void setupLoRandom() at startup, and uint8_t getLoRandomByte() when you need a random byte. This code creates a stock of 256 bytes at startup to make things easier. Remember you need to reset LoRa settings when you need RNG...

This code is used in BastWAN DHKE to provide random numbers for the public and private keys.
