a) Arduino LoRaWAN, 15'

• Get an account at https://thethingsnetwork.org/
• Register a TTN application, and register two devices.
• Get ABP keys for one device, OTAA keys for another.
• Set these keys in the LoRaWAN .ino code examples.
• Make sure to use the right code for your hardware.
  (The pin mapping varies for ESP8266, nRF52840.)

b) TTN integrations, 15'

• Read the TTN MQTT and Webhooks API docs.
• Use the Raspberry Pi as your application backend.
• Use a MQTT SUB client to log incoming messages.
• Set up an HTTP Logger to see TTN Webhook calls.

c) LoRaWAN use cases, 15'

• Which applications become possible with LoRaWAN?
• Does free wide area connectivity change anything?
• Sketch the reference model for an application.
• Find a case that clearly beats Wi-Fi, 3/4G.
