Fork of mDot_LoRa_Connect_Example by MultiTech

The project is a starting point for the AS923 channel plan.

Default frequencies are 923.2 and 923.4 Join Datarate is set to DR2:SF10BW125 Additional channels can be added in JoinAccept message or through new channel mac commands

New MAC commands in LoRaWAN 1.02 have NOT been included to set the DwellTime and MaxEIRP Overriding this function is available to someone who would like to do this. virtual uint8_t HandleMacCommands(uint8_t* payload, uint8_t index, uint8_t end_index);
