This is part 57 of the LoRa/LoRaWAN tutorial.

In this tutorial I will demonstrate how to send uplink messages from an end device to The Things Stack Community Edition network (V3).
I will also demonstrate how to send downlink messages from The Things Stack Community Edition network (V3) to an end device.

I have written a detailed tutorial how to send messages to/from The Things Stack Community Edition (V3):

In this video I will not go step-by-step thru the detailed tutorial, instead I will only show the most relevant information.

Used libraries, Arduino sketch, and payload formatter:
- Adafruit Unified Sensor library
https://github.com/adafruit/Adafruit_...
- DHT sensor library
https://github.com/adafruit/DHT-senso...
- MCCI LoRaWAN LMIC library
https://github.com/mcci-catena/arduin...
- The Arduino sketch

- Payload formatter: Javascript decodeUplink

The HopeRF RFM95 LoRa transceiver module does not have a built-in DevEUI or AppEUI.
In such case you should let the TTSCE console generate the required DevEUI or AppEUI.

The AppEUI, DevEUI and AppKey are used in the Arduino sketch.

In this Arduino sketch the DevEUI or AppEUI must be converted to an array of 8 bytes in LSB order.
The AppKey must converted to an array of 16 bytes in MSB order.
I have created an online tool which converts these values to an bytes array in its correct order (LSB / MSB):
