/** mDot_TTN_Node - Simple mDot temperature sensor using Dallas Semiconductors DS18B20 OneWire temperature sensor.
 * It used the AUTO_OTA join mode with parameters for The Things Network.
 *
 *
 * Uses MultiTech mDot developer board http://www.multitech.com/models/94558010LF
 * Requires a MultiTech MultiConnect Conduit http://www.multitech.com/models/94557203LF
 * http://www.multitech.net/developer/software/lora/conduit-mlinux-convert-to-basic-packet-forwarder/
 * http://forum.thethingsnetwork.org/t/setting-up-multitech-conduit-gateway-for-ttn/216/35
 *
 * Register a device and generate a random AppKey for the currently used application Id:
 * (You need to use your own device IDs, the ones shown here are examples only)
 *
 *./ttnctl devices register 0080000000000000
 * INFO Generating random AppKey...
 * INFO Registered device                        AppKey=000102030405060708090A0B0C0D0E0F DevEUI=0080000000000000
 *
 * or to specify the same AppKey for a new device or to reregister the same device again:
