LoRaWAN gateways and devices

CHERT IoT runs a full LoRaWAN network server (ChirpStack). Your LoRa uplinks arrive on the same dashboard as your Wi-Fi devices.

1. Register a device

In the portal, open LoRaWAN → Register a LoRa device. You get a DevEUI and an AppKey (OTAA, EU868, LoRaWAN 1.0.3). A matching device is created for you automatically.

2. Flash your node

Program your LoRaWAN node (Arduino MKR WAN, Heltec, RAK, …) for OTAA with:

  • DevEUI — from the portal
  • AppKey — from the portal
  • JoinEUI/AppEUI — all zeros (0000000000000000)
  • Region EU868

3. Point a gateway at the platform

Configure your gateway's Semtech UDP packet forwarder to send to:

  • Server address: chertiot.com
  • Port (uplink & downlink): 1700
  • Region: EU868

That's it — once the gateway is online and your node joins, decoded uplinks appear as telemetry on your device in My dashboard. Send a numeric payload (a decoded object in your codec) and it charts automatically; raw payloads arrive as raw_hex plus rssi/snr.

No hardware yet?

The platform includes a simulator so you can see the flow end to end before a gateway arrives — ask your instructor, or watch your dashboard after registering (a demo uplink is injected for new LoRa devices on staging).
