Sending data to TheThingsNetwork with LoRaWAN

How to send data to TheThingsNetwork (TTN) with the Featherwing RFM95W LoRaWAN module.

Running the example

Get TTN keys

  • Get a TTN account, open the TTN console and add a TTN application.
  • Add a TTN device, change its settings to Activation Method: ABP and uncheck Frame Counter Checks.
  • Check the the settings tab to get your TTN Device Address, Network Session Key and App Session Key (copy as MSB).

Set up your device

  • Set up the hardware, connect it to your computer via USB.
  • Copy the libraries to the lib directory on the CIRCUITPY drive.
  • Set ttn_dev_address_msb, ttn_net_session_key_msb and ttn_app_session_key_msb in the lorawan_abp.py example.
  • Copy the content of lorawan_abp.py to code.py on the CIRCUITPY drive.

See received data in TTN

  • Check the data tab of your device in the TTN console to see incoming data packets.
  • If no data shows up after 15 minutes, make sure you have TTN network coverage.

Libraries

From the CircuitPython libraries bundle:

  • Copy lib/adafruit_tinylora/* (see source and docs).
  • Copy lib/adafruit_bus_device/* (see source and docs).
