Thing Innovations / Mbed 2 deprecated mDot_TTN_OTAA_Node Featured

Demonstration TTN OTAA node

Dependencies:   BME280 DS1820 libmDot mbed-rtos mbed

This is an example application for the MultiTech mDot and connects to The Things Network using Over The Air Activation (OTAA). It sends data from a Dallas Semiconductors DS18B20 OneWire temperature sensor.

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:

./ttnctl devices register 0080000000000000 000102030405060708090A0B0C0D0E0F

./ttnctl devices info 0080000000000000 Dynamic device:

DevEUI: 0080000000000000 {0x00, 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00}

AppKey: 000102030405060708090A0B0C0D0E0F {0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A, 0x0B, 0x0C, 0x0D, 0x0E, 0x0F}

Copy the AppEUI and AppKey values provided in hex array notation above to the AppEUI and AppKey parameters below.
