STICKER Quick Start Guide

Welcome! This page helps you power up, provision, and activate your STICKER device and connect it to your preferred LoRaWAN Network Server (ChirpStack, The Things Stack, or custom backend).

Before You Start​

What STICKER Is​

STICKER is an open IoT platform based on the STM32WL SoC with integrated LoRaWAN connectivity and software-selectable proprietary LoRa P2P mode. It is a compact, battery-powered sensor platform built on Zephyr RTOS, running catalog applications like STICKER Clime, Input, and Motion.

For technical details, see the Hardware Description.

You Will Need​

  • STICKER device (Clime / Input / Motion variant)
  • 2× AA batteries (1.5V alkaline or lithium)
  • A LoRaWAN Gateway within range
  • A LoRaWAN Network Server (ChirpStack / TTS / custom LNS)
  • A smartphone with NFC and the HARDWARIO Manager app installed

Step 1: Identify Your STICKER Variant​

STICKER comes pre-flashed with one of the catalog applications:

  • STICKER Clime — Temperature, humidity, light & barometric pressure monitoring.
    Documentation →
  • STICKER Input — External sensors (1-Wire, Machine Probe) and industrial inputs (S0 pulse, 0–30 V logic).
    Documentation →
  • STICKER Motion — Ultra-low-power PIR motion detection and 3-axis acceleration tracking.
    Documentation →

Step 2: Power Up & Understand Factory Defaults (v1.4.0+)​

  1. Open the enclosure and insert two AA batteries according to the polarity markings.
  2. Observe the LED Boot Sequence: Red (0.5 s) → Yellow (0.5 s) → Green (1.5 s).
Factory Default: Radio-Silent Mode

Starting with firmware v1.4.0, STICKER ships in Radio-Silent Mode (radio-mode disabled) to prevent battery drain during shipping. The device will not automatically attempt a LoRaWAN Join upon battery insertion until activated via NFC.

  1. Status LED Indication: After boot, the LED will flash 1× Yellow every 3 seconds, indicating that the device is running normally but the radio is switched off.

Step 3: Configure & Activate via NFC​

STICKER uses encrypted NFC for local configuration. Configuration works even without batteries inserted thanks to NFC energy harvesting.

Mobile App Setup

For complete instructions on extracting provisioning keys, configuring parameters, and managing templates, see the HARDWARIO Manager guide.

  1. Open HARDWARIO Manager on your mobile phone.
  2. Read device info to extract the factory DevEUI, AppEUI/JoinEUI, and Claim Token.
  3. Configure your LoRaWAN parameters (DevEUI, AppEUI, AppKey, activation mode).
  4. Tap the phone against the STICKER enclosure to write settings:
    • Writing configuration automatically enables radio-mode and triggers a LoRaWAN Join.
    • The LED status heartbeat will change from 1× Yellow (radio off) to Yellow + Red (joining).
    • Upon successful join, the LED transitions to 1× Green heartbeat and transmits a Device Info on Join payload.

Step 4: Register on your LoRaWAN Network Server​

ChirpStack v4​

  1. Register the device using the DevEUI, JoinEUI, and AppKey obtained via HARDWARIO Manager.
  2. Assign the STICKER payload decoder script.
  3. Follow the full setup guide: ChirpStack LNS Integration.

The Things Stack (TTS / TTN)​

  1. Add a new end device using OTAA or ABP provisioning keys obtained via HARDWARIO Manager.
  2. Import the payload decoder.
  3. Follow the full setup guide: The Things Stack Integration.

Step 5: Post-Commissioning Verification​

Once registered and connected:

  • Verify Uplinks: Confirm that the initial Device Info uplink (firmware version, battery status, reset cause) and regular sensor data packets arrive at your LNS dashboard.
  • Check LED Status: A single green flash every 3 seconds confirms optimal network link and healthy operation.
  • Adjust Schedules: Use NFC via HARDWARIO Manager or LoRaWAN Downlink commands (fPort 85) to fine-tune sampling and uplink intervals.
STICKER Input Wiring

If using STICKER Input, review the terminal block and DIP switch instructions before connecting external probes: STICKER Input Wiring Guide.

Troubleshooting Checklist​

  • Device dark (No LED boot carousel)? Check battery orientation or replace batteries.
  • LED flashing 1× Yellow endlessly? The radio is in Radio-Silent Mode. Apply configuration via NFC using HARDWARIO Manager to activate transmission.
  • LED flashing Yellow + Red? The device is attempting to Join the network but receiving no response. Check gateway proximity, frequency plan, and AppKey matching.
  • LED flashing Red + Yellow (alternating)? Configuration corrupt. Re-apply device settings using HARDWARIO Manager over NFC.
  • No uplinks received? Verify that the payload decoder is properly assigned in ChirpStack or TTS.
