General Platform Updates​

Upcoming Platform Updates

The following features and hardware extensions are currently in active development for upcoming releases:

  • [FW/HW] Acoustic Buzzer Module: Hardware expansion support for STICKER Clime and STICKER Input variants (installed in place of the PIR sensor slot; incompatible with STICKER Motion)
  • [HW/FW] Analog Probe Converter: Expansion interface module for STICKER Input enabling readout of Pt100, Pt1000, and thermocouple probes

2026-10-19 – v2.0.0​

  • [FW] Breaking release; action required when upgrading from v1.4.x: update HARDWARIO Manager together with the firmware, switch to the v2.0.0 ttn.js decoder (in a mixed fleet pick the decoder by the firmware version in Info), re-provision alarm rules and the history channel selection, re-set cap-gpio-* and radio-link-check-*, and wipe the old NFC NDEF records once. Stored history starts empty after the upgrade and there is no supported downgrade · Release notes · GitHub Release
  • [FW] LoRa P2P radio mode: radio-mode p2p links STICKER to a HARDWARIO FIBER modem / ProXimos Hub over the HARDWARIO TOWER radio protocol (AES-CCM, gateway-acknowledged sends, on-air pairing) with no LoRaWAN network; telemetry, alarms, commands, history and network time work as over LoRaWAN. One firmware image does both radios
  • [FW] One-tap NFC on Android and iOS: all phone commands run through the ST25DV fast-transfer mailbox in a single hold; the tag carries no NDEF record, so NFC now needs a powered device (battery-less configuration and Android tap-to-launch were removed)
  • [FW] Safer claiming: the claim token is readable only from a powered device while the claim window is open; claim_done / claim_active close and re-open it
  • [FW] Configuration announce: after every boot/join, and every interval-announce hours (default 24 h), the device sends its Info plus a settings summary; get_settings requests it on demand
  • [FW] Radio diagnostics and paged answers: new get_radio_state command (link state, SF/DR, TX power, RSSI/SNR, duty cycle); answers and telemetry that do not fit one frame arrive as numbered pages
  • [FW] LoRaWAN improvements: AS923 region, fixed data rate with ADR off (lrw-datarate), link-loss recovery in about 4–5 h instead of 9–10 h, duty-cycle-aware sending, DevStatusAns answered
  • [FW] Sensor channel model: every sensor value is a (slot, channel) that can be alarmed and recorded; history-channels replaces history-sensors; a 1-Wire slot expects a sensor type and raises sensor_mismatch otherwise
  • [FW] Alarm engine updates: alarms_replace rewrites the whole rule table in one message; threshold dwell is now a hysteresis in the channel's units; rate rules count within dwell seconds; motion-started/ended and stillness rules; alarm state in every telemetry frame; optional confirmed alarms (radio-alarm-ack) and buzzer melodies (alarm-buzzer-mode)
  • [FW] GP pins and inputs: cap-gpio-mode and cap-gpio-input-a/-b replace the old input/PIR/buzzer capability flags; inputs can be digital, 0–24 V analog or an S0 pulse counter; cap-sht turns the onboard temperature/humidity sensor off
  • [FW] Robustness: below 1.8 V at boot the device blinks red and switches off instead of boot-looping; a CPU fault reboots at once and is reported in the next Info; history timestamps follow the RTC; a missing reading decodes as null; factory_reset now also clears pulse counters and history
  • [FW] Renamed shell parameters: lrw-deveui / lrw-appkey → radio-deveui / radio-appkey (values kept); lrw-link-check-* → radio-link-check-* (reset to defaults); ats lrw → ats radio
  • [FW] Provisioning firmware image: each release now also ships hio-sticker-<version>-provisioning.hex
  • [Apps] STICKER Input: 0–24 V analog inputs and S0 pulse counting
  • [Apps] STICKER Motion: motion-started/ended and stillness alarm rules
  • [Apps] STICKER Clime: all onboard values (incl. barometer temperature) can be alarmed and recorded; the onboard SHT4x can be switched off

2026-08-18 – v1.4.0​

  • [FW] Remote control over LoRaWAN: Full configuration, status querying, and control commands over fPort 85 (set_param, get_param, get_config, get_info, reset/rejoin) without physical or NFC access
  • [FW] Device Info on Join: Automatic diagnostic telemetry uplink (serial, FW version, reset cause, claim token, radio mode, battery voltage) transmitted on every network Join and clock sync
  • [FW] Real-time clock (RTC): Wall-clock tracking with network time synchronization (DeviceTimeReq), readable/settable via NFC, LoRaWAN downlinks, or shell (clock)
  • [FW] Sensor history (Store-and-forward): Samples buffered in a dedicated 32 KB flash ring partition during network outages, with replay on request over LoRaWAN (req_history) or NFC (req_history_page)
  • [FW] Alarm engine & fPort 3 alerts: Dynamic multi-slot rules (threshold, state, rate) with integrated dwell noise filtering, low-battery alerts, and no-data watchdog reporting on fPort 3
  • [FW] Encrypted NFC access: Secured local communication using AES-CCM encryption (hio.stck:cmd / hio.stck:rsp) and anti-replay nonce protection
  • [FW] Write-once Claim Token: Immutable 128-bit claim token (config claim-token) for instant cloud onboarding prior to network Join
  • [FW] Factory default Radio-Silent mode: Transceiver disabled out of the box (radio-mode off) to protect battery life during shipping; activated via NFC
  • [FW] Unified LED signalling scheme: Severity-ordered heartbeat patterns (join state, degraded link, active alarms, radio status) and dedicated NFC/input action blinks
  • [FW] Diagnostic CLI suite (ats): Renamed diagnostic tool family tester → ats; added ats lrw reset, ats lrw compose, ats lrw lc, and raw protobuf frame injection (ats cmd lrw|nfc)
  • [FW] Immutable firmware security model: Deliberately removed DFU update capabilities (enter_dfu) to ensure zero remote attack surface (firmware flashable strictly via SWD pads)

2026-05-25 – v1.3.4​

  • [FW] Unified alarm/event delivery: immediate LoRaWAN send and centralized LED handling
  • [FW] Fixed US915/AU915 sub-band selection and NFC sub_band field ingestion
  • [FW] Fixed LoRaWAN 1.0.x OTAA, AppKey is now correctly fed into the NwkKey slot
  • [FW] App sensor sample timer now starts even on partial sensor init failure

2026-05-15 – v1.3.2 / v1.3.3​

  • [FW] LoRaWAN sync word switches to private only when explicitly configured
  • [FW] Calibration mode forces public LoRaWAN network
  • [FW] Added ChirpStack v3 decoder compatibility wrapper (ttn.js)

2026-05-14 – v1.3.1​

  • [FW] Fixed calibration mode: activates when config calibration true is set via shell or NFC, not only on dual-magnet detection at boot
  • [FW] Calibration flag cleared at start of calibration init, so the run is one-shot (2h deadline or earlier reset returns device to normal OTAA)

2026-05-04 – v1.3.0​

  • [FW] Calibration mode with dual-magnet Hall sensor detection (see 2026-04-21)
  • [FW] Comprehensive bug fix release: LoRaWAN state machine, DS28E17, sensor init, NFC config ingestion (see 2026-02-17 and 2026-04-01 for full details)

2026-04-21​

  • [FW] Added calibration mode with Hall sensor activation

2026-04-01​

  • [FW] Fixed DS28E17 machine probe initialization reliability: retries write_config and reads back echoed register for verification
  • [FW] Fixed atomic state read in machine probe scan

2026-02-17​

  • [FW] Reduced PYQ1648 (PIR) IRQ latency from 2.5 ms to 100 µs for faster motion response
  • [FW] Added analog pinctrl for I2C1 sleep state: reduces idle current leakage
  • [FW] Added NVS config version check: resets defaults on schema mismatch after firmware update
  • [FW] Fixed GPIO pin conflict: skips input init when PIR is enabled
  • [FW] Added delay after SI7210 ONEBURST trigger to avoid stale hall-effect readings
  • [FW] Added reset_counts shell commands for hall and input counters
  • [FW] Fixed LoRaWAN state machine counters (changed from uint8_t to int to prevent overflow)
  • [FW] Atomically snapshot and clear notify flags in compose, which prevents race conditions
  • [FW] Split LED message queue to reduce blink caller stack usage
  • [FW] Added intermediate watchdog feeds during boot init sequence
