 * This uses OTAA (Over-the-air activation), where where a DevEUI and
8
 * application key is configured, which are used in an over-the-air
9
 * activation procedure where a DevAddr and session keys are
10
 * assigned/generated for use with all further communication.
11
 *
12
 * To use this sketch, first register your application and device with
13
 * the tloraserver, to set or generate an AppEUI, DevEUI and AppKey.
14
 * Multiple devices can use the same AppEUI, but each device has its own
15
 * DevEUI and AppKey.
16
 *
17
 * Do not forget to define the radio type correctly in config.h.
