0.0.5

Major UI Refactor and OTA Workflow Optimization

Platform Support: Android, iOS, macOS

New Features

• Simplified OTA Upgrade Screen - Refactored multi-page flow into a single-page three-step process
  • Step 1: Discover Services - Discover device services (auto-pair on connect)
  • Step 2: Select Firmware - Select firmware file
  • Step 3: Start OTA Upgrade - Start upgrade
• Smart Bottom Hint Bar - Displays dynamic operation hints based on current state
• Auto-Return After OTA - Automatically returns to scan screen 2 seconds after upgrade completes
• Simplified Device Scan Screen - Removed "OTA only" toggle, scans all devices by default

Bug Fixes

• Fixed Pair State Check Logic - Uses bondState.first to wait for stream update, avoiding repeated pairing dialogs
• Fixed GATT 133 Error - Disconnects existing connection before reconnecting to prevent connection conflicts
• Fixed Unresponsive Button After Pairing - Re-checks state after pairing to ensure UI updates correctly
• Removed Redundant Step 1 Pair Card - Pairing now happens automatically during service discovery

Technical Improvements

• BLE Connection Optimization - Added pre-connect checks and delays in connect() method to avoid GATT cache conflicts
• Optimized Pairing Timing - Only triggers createBond() when device is not bonded; directly connects for bonded devices
• Enhanced Error Logging - Added detailed bond state logs for debugging

Notes

• discoverServices() is Required - BLE requires rediscovering services after each connection; this is standard BLE protocol behavior
• Bootloader Mode May Trigger Pairing - If device changes MAC address after entering bootloader mode, system will treat it as a new device and request pairing
