Hop Table Generation

The LoRaSerial uses a novel technique for generating the frequencies it uses for transmission. In order to prevent other radios and other LoRaSerial products from transmitting over each other a unique hop table must be generated. To achieve this, a unit’s settings needed for a working link are combined into a 16 bit number that is used as a random seed. A table, based on the min/max frequencies and the number of channels, is then randomly sorted using the random seed. This guarantees that two radios, even with slightly different settings, have very different hop patterns.
