2.1.2 LORAWAN_Reset

Definition: This function automatically resets the LoRaWAN stack software and initializes the stacks with the parameters for the selected ISM band. During this Reset routine:

MAC DB is initialized with default parameters
LoRaWAN regional parameters module is initialized
Radio layer default DB initialization is triggered

The Reset routine must be called after every software reset of the stack. To change the regional band dynamically, Reset routine calls the new ISM band, which un-initializes an old regional parameter and re-initiates the new ISM band. If the ISM band is same as the one stored in DB, the regional parameter initializes the same default ISM band.
