General Platform Updates​

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 — prevents race conditions
  • [FW] Split LED message queue to reduce blink caller stack usage
  • [FW] Added intermediate watchdog feeds during boot init sequence
  • [FW] Added CRC16 verification on DS28E17 read data

2026-01-30 — v1.2.0​

  • [FW] Fixed LED debug mode sequence — green blink now correctly precedes yellow

2025-12-15 — v1.1.0​

  • [FW] Implemented LoRaWAN JOIN retry mechanism — device retries joining the network after failed attempts

2025-11-23 — v1.0.0​

  • [FW] Initial public release of STICKER firmware
  • [FW] LoRaWAN connectivity (Class A)
  • [FW] MIFARE/NFC tag support via DS28E17
  • [Apps] STICKER Clime — initial release (temperature, humidity)
  • [Apps] STICKER Input — initial release (digital inputs, pulse counting)
  • [Apps] STICKER Motion — initial release (PIR motion detection)
