## [1.9.4] - 2026-05-14
|
|
|
|
### Fixed
|
|
|
|
- **Date timezone** (#5): Date string now uses local time, so date rolls over at local midnight instead of UTC midnight
|
|
- **Weather periodic refresh** (#7): Removed `WEATHER_SUCCESS` state that permanently blocked periodic weather updates after first fetch; also fixed "Last update" counter showing raw timestamp instead of elapsed seconds
|
|
- **WiFi connects to wrong network** (#3): `WiFi.begin()` without params is now skipped when a saved SSID exists, preventing connection to SDK-cached open hotspots and config corruption
|
|
|
|
### Changed
|
|
|
|
- WiFi startup: SDK-cached credentials only attempted on first boot (no saved SSID); subsequent boots go directly to saved credentials
|
|
- ArduinoJson: `StaticJsonDocument` → `JsonDocument` for compatibility with ArduinoJson v7
|
|
|
|
### Removed
|
|
|
|
- Unused `weekday` variable in NTP DST calculation (compiler warning)
|
|
|
|
### Internal
|
|
|
|
- Split `clock_ntp_ota_v1.9/` directory renamed to `weather_clock/` — version no longer baked into path
|
|
- Removed internal development documents from repository
|
|
|
|
## [1.9.3] - 2026-01-06
|
|
|
|
### Changed
|
|
|
|
- Refactored monolithic 2,100-line `.ino` into modular structure:
|
|
`display.cpp`, `ntp_client.cpp`, `weather.cpp`, `web_server.cpp`, `wifi_manager.cpp`
|
|
|
|
## [1.9.2] - 2026-01-06
|
|
|
|
### Fixed
|
|
|
|
- **CRITICAL**: WiFi credentials no longer cleared on connection failure
|
|
- Previous behavior erased SSID/password after failed connection attempts
|
|
- Now credentials persist indefinitely through WiFi outages
|
|
- OTA update credential loss issue (SDK credentials now tried first, then EEPROM)
|
|
|
|
### Added
|
|
|
|
- **WiFi Resilience**: Infinite retry with exponential backoff (5s → 10s → 20s → ... → 5min max)
|
|
- **Fallback AP**: "TJ56654-Setup" enabled after ~5 min of failed attempts
|
|
- Device continues retry attempts while AP is active (dual STA+AP mode)
|
|
- AP automatically disabled when WiFi reconnects
|
|
- **"No WiFi" display**: Shows retry countdown instead of numeric counter
|
|
- **"!" indicator**: Shown in date line when WiFi is disconnected
|
|
- **SDK credentials support**: Tries WiFiManager-stored credentials first
|
|
|
|
### Changed
|
|
|
|
- Clock continues running with last synced time during WiFi outages
|
|
- Improved user experience during network failures
|
|
- Removed aggressive credential clearing behavior
|
|
|
|
### Network Activity
|
|
|
|
- NTP sync: 1 hour interval (pool.ntp.org:123 UDP)
|
|
- Weather fetch: 30 min interval (api.open-meteo.com HTTP)
|
|
- mDNS: continuous (224.0.0.251 UDP multicast)
|
|
- ~50 requests/day total
|
|
|
|
## [1.9.1] - 2026-01-03
|
|
|
|
### Fixed
|
|
|
|
- **CRITICAL**: WiFi startup sequence - synchronous connection in setup() to ensure proper initialization order
|
|
- Display blank screen for 10+ seconds on boot (now shows time after ~15 seconds)
|
|
- "DNS resolution failed" errors during startup
|
|
- Sunrise/sunset labels cut off on 128px screen (removed labels, arrows are self-explanatory)
|
|
|
|
### Changed
|
|
|
|
- Hybrid WiFi model: synchronous in setup(), async reconnect in loop()
|
|
- Display formatting: superscript degree symbol and lowercase 'c' for temperature
|
|
- Sunrise/sunset screen now shows daylight duration (e.g., "Day 9h 41m") instead of static "Sun Times" text
|
|
|
|
### Documentation
|
|
|
|
- Added detailed v1.9.1_HYBRID_FIX.md explaining startup sequence problem and solution
|
|
|
|
## [1.9.0] - 2026-01-02
|
|
|
|
### Added
|
|
|
|
- Fully async architecture (zero blocking operations in loop)
|
|
- Custom async NTP implementation (manual UDP packet handling)
|
|
- Async HTTP weather fetch (AsyncHTTPRequest library)
|
|
- Exponential backoff retry logic for network failures
|
|
- Independent epoch tracking for accurate time between NTP syncs
|
|
|
|
### Changed
|
|
|
|
- Replaced blocking NTPClient with custom async UDP implementation
|
|
- Replaced blocking HTTP weather with AsyncHTTPRequest
|
|
- Removed all delay() calls from loop()
|
|
- WiFi connection now async (later fixed in v1.9.1)
|
|
|
|
### Performance
|
|
|
|
- Loop time: 10ms → <1ms (10x improvement)
|
|
- Weather fetch: 1-10s blocking → 0ms
|
|
- NTP sync: 5-20s blocking → 0ms
|
|
- WiFi reconnect: 15s blocking → 0ms
|
|
- OTA updates now work during active weather fetching
|
|
|
|
### Technical
|
|
|
|
- RAM usage: +536 bytes (36,980 → 37,516)
|
|
- Flash usage: +1040 bytes (407,500 → 408,540)
|
|
- IRAM: 61,987 bytes (94% - stable)
|
|
|
|
## [1.8.0] - 2026-01-01
|
|
|
|
### Security
|
|
|
|
- **CRITICAL**: Removed hardcoded WiFi credentials
|
|
- Integrated WiFiManager for secure captive portal setup
|
|
- Added config validation (magic number check)
|
|
- Input sanitization to prevent buffer overflows
|
|
|
|
### Fixed
|
|
|
|
- IRAM overflow crisis (94% → 70% via ICACHE_FLASH_ATTR)
|
|
- NTP interval bug (config value was ignored, always used hardcoded 1 hour)
|
|
- Boolean parsing errors in JSON config import/export
|
|
- Infinite loop protection in display mode rotation
|
|
- Memory leaks from String concatenation in web handlers
|
|
|
|
### Changed
|
|
|
|
- Web responses now use chunked transfer (eliminated 140+ String concatenations)
|
|
- Applied ICACHE_FLASH_ATTR to 26 functions (moved code from IRAM to Flash)
|
|
- Improved error handling throughout codebase
|
|
|
|
### Performance
|
|
|
|
- Peak heap usage reduced by ~8KB
|
|
- EEPROM validation prevents loading corrupted config
|
|
|
|
