- Add "start detection" button (not auto-start on page load)
- Send control=0x01 only when user clicks button
- Accumulate PD values across all ADC frames during scan
- Monitor run_state: wait for 0x01→0x00 transition as completion signal
- Calculate PD averages on completion
- Send treatment command (control=0x02) on "next" with calculated params
- TODO: plug in full NR diagnosis algorithm when PD→region mapping confirmed
Remove all fitting detection logic (setParams, fitting event listener,
timeout). User manually confirms wearing, then proceeds to detection
page. No BLE commands sent on this page.
wear-check:
- Send weak pulse light (brightness=26) to trigger FFE4 fitting report
- Timeout degrades to pass (backward compat with 17-byte firmware)
- Sync _resolved flag prevents double-resolve
treating:
- Only treat run_state=0x00 as completion after seeing run_state=0x02
(prevents false completion on startup)
- Sync _finishing flag replaces async data.completed for race prevention
- onStatus preserves paused state during fitting loss (|| fittingLost)
- Remove dead _fittingTimer reference from onUnload
auto-scan:
- Sync _completed flag in _scanComplete prevents double-build
- Listen for 'fitting' event: detect skin detachment, pause on loss,
resume on re-attach
- Listen for 'run_state' event: detect device fault (0xFF) and IDLE
completion (0x00)
- Low battery warnings: toast at <=10%, force stop at <=5%
- Guard finishAsComplete against double-completion
- Proper cleanup of all new event listeners on unload
Firmware does R→UV→Y→IR sequential scan autonomously. Miniprogram
now listens for 4 consecutive ADC notifications, storing each as a
separate spectrum group. Also listens for run_state=IDLE as scan
completion signal. Displays all 4 spectrum groups with PD1-PD7 bars.
Stores full scan data in globalData.lastScanData for diagnosis phase.
Listen for 'fitting' event from FFE4 Byte17 (0=not fitted, 1=fitted).
10s timeout if no fitting signal received. Removes vendor_33 bypass
that always returned ok.
- Extract _cleanup() to properly unregister ADC listener + clear timers
- ADC callback unregisters itself on first receive (prevent duplicates)
- setParams failure now stops scanning and clears all state
- Timeout handler unregisters ADC listener
- Add BLE connection check before scan
- SCAN_TIMEOUT 8s → 12s (must exceed hold_time 10s)
- Pre-compute barWidth in JS instead of float math in WXML
- Error only shows when scanning is false
- Send scan command: all 5 regions LED on, brightness 128
- Listen for ADC notify (17 bytes) instead of broken queryStatus
- Parse and display PD1-PD7 values with visual bars
- Show VBAT/battery info
- Store scan PD data in globalData for Phase 3 smart adjustment
- 8s timeout fallback, stop LED on page unload
Region name mapping corrected to match actual hardware IO positions:
- 0x01: 左区→右区, 0x02: 右区→左区
- 0x08: 下区→中区, 0x10: 中区→下区
Auto-scan no longer shows timeout error, proceeds to next step instead.
- parseDeviceId accepts hex with spaces (e.g. "672B6D5A 4DCD861")
- BLE scan does exact match on "JW_<device_id>" when target is known
- Manual input placeholder updated to show new format
Replace '光子美容仪' with '智美'/'智能面膜'/'我的设备' throughout.
Replace '护理' with '使用' in all UI text.
Replace '皮肤' with '检测'/'智能' where applicable.
Replace 🌸 with 💎 for brand identity.
Internal code (variable names, API paths, file names) unchanged.
- ADC (17-byte) now emits 'adc' + 'battery' events, not 'status'
- Fixes CRITICAL timer jump: remaining_ms:0 was resetting countdown
- Drop ADC packets with bad XOR checksum
- treating.js + index.js subscribe to 'battery' for live battery updates
- onStatus only updates remaining_ms when > 0
