ChirpStack v4

ChirpStack v4 is an open-source LoRaWAN Network Server for self-hosted, private network deployments.

Prerequisites
  1. Ensure ChirpStack v4 is installed and operational. See the ChirpStack Installation Guide.
  2. Use HARDWARIO Manager to extract your device credentials via NFC before creating end-device profiles in ChirpStack.

Device Credentials & NFC Extraction​

Before registering a STICKER unit in ChirpStack v4, extract its factory keys and provision radio settings over NFC:

  1. Open HARDWARIO Manager on an NFC-enabled smartphone.
  2. Tap the phone against the STICKER enclosure to read device information.
  3. Record the DevEUI, JoinEUI/AppEUI, and AppKey (for OTAA) or static session keys (for ABP).
  4. Verify that radio-mode is enabled so the device initiates a Join attempt upon provisioning.

Device Profile & Payload Codec Setup​

When configuring your STICKER Device Profile in ChirpStack v4:

  • Codec Driver: Select JavaScript codec and paste the official STICKER decoder script (ttn.js).
  • Bidirectional Capabilities: The codec automatically parses telemetry uplinks on fPort 2, alarm alerts on fPort 3, and formats remote JSON downlinks on fPort 85 (see Downlink Commands).
