Added comprehensive network details page accessible by clicking on scan results. Features Implemented: ✅ Clickable Network List Items (Acceptance Criteria #1): - Each network item in scan results is now clickable - Clicking navigates to /scan/details?id=<network_index> - Added visual feedback on hover (background color change) - Mobile-friendly touch targets with inline onclick handlers ✅ Network Details Page (Acceptance Criteria #2): - New route handler handleScanDetails() at /scan/details - Back navigation button to return to scan results - Graceful error handling for invalid/missing network IDs - Scan results cached in memory to avoid re-scanning ✅ Information Display (Acceptance Criteria #3): Basic Network Information: - Network Name (SSID) with special handling for hidden networks - MAC Address (BSSID) formatted as XX:XX:XX:XX:XX:XX - Handles missing BSSID gracefully Signal Information: - RSSI displayed in dBm - Signal Quality calculated as percentage with 8-level descriptive scale: * 100% Excellent (Very Close) ≥ -30 dBm * 90% Excellent ≥ -50 dBm * 80% Very Good ≥ -60 dBm * 70% Good ≥ -67 dBm * 60% Fair ≥ -70 dBm * 50% Weak ≥ -80 dBm * 30% Very Weak ≥ -90 dBm * 10% Extremely Weak < -90 dBm - Visual signal indicators with emoji icons - Color-coded quality bar (green/yellow/orange/red) Channel Information: - Channel number with frequency band (2.4GHz or 5GHz) - Channel congestion analysis: Clear/Light/Moderate/Heavy/Severe - Counts networks on same channel with color-coded indicators Security Information: - Encryption type with icons for all 9 WiFi auth modes: * Open, WEP, WPA, WPA2, WPA/WPA2, WPA2 Enterprise, WPA3, WPA2/WPA3, WAPI - Security level assessment (None/Weak/Moderate/Good/Excellent) - Color-coded security ratings - Security warnings for open and WEP networks Connection Analysis/Recommendations: - Automated recommendations based on signal strength - Security assessment warnings - Channel congestion impact analysis - Clear ✅/⚠️ /❌ indicators for quick evaluation ✅ UI/UX Requirements (Acceptance Criteria #4): - Consistent purple gradient theme matching existing interface - Responsive design with proper spacing - Card-based layout with background colors for sections - Emoji icons throughout for visual recognition - Clean section-based information hierarchy ✅ Performance & Memory (Acceptance Criteria #5): - Scan result caching structure (CachedScanResult) - Supports up to 50 cached networks - 5-minute cache timeout (300000ms) - Uses PROGMEM and F() macro for static strings - Pre-allocated String buffers (html.reserve(8192)) - Cache validation before displaying details - Memory-efficient: Flash 83.1% (was 82.4%), RAM 16.4% (was 15.8%) ✅ Navigation & Accessibility (Acceptance Criteria #6): - Back to Scan Results button with absolute positioning - Breadcrumb-style navigation structure - Clickable entire network row (not just text) - Inline hover effects for visual feedback ✅ Edge Cases & Error Handling (Acceptance Criteria #7): - Cache expiration check with redirect to /scan - Invalid network ID validation with redirect - Out of bounds index checking - Missing BSSID handling with "Not Available" message - Hidden network SSID display as "<Hidden Network>" Technical Implementation: Data Structures: - CachedScanResult struct stores SSID, RSSI, channel, encryption, BSSID - Static array cachedNetworks[50] for result storage - lastScanTime timestamp for cache invalidation - isCacheValid() function checks timeout Route Registration: - Added /scan/details route in startWebServer() - handleScanDetails() function declaration in web_server.h Scan Page Modifications: - Modified handleScan() to cache results after scan - Made network list items clickable with onclick handlers - Added hover effects with inline onmouseover/onmouseout - Removed WiFi.scanDelete() to preserve results - Added hint text: "💡 Click on any network to view detailed information" - Hidden network handling in scan list Memory Optimization: - All static HTML strings use F() macro - Color values and descriptions stored efficiently - Switch statement for encryption type mapping - Minimal string concatenation with pre-allocation Build Results: ✅ ESP32dev: Flash 83.1% (1,088,625 bytes), RAM 16.4% (53,692 bytes) ✅ Feather ESP32-S3: Flash 71.9% (1,036,493 bytes), RAM 16.0% (52,496 bytes) Testing Checklist Progress: ✅ Builds successfully on both ESP32dev and Feather boards ✅ All encryption types handled with proper icons and descriptions ✅ Signal quality calculation matches acceptance criteria ranges ✅ Channel congestion correctly counts networks ✅ Back navigation implemented ✅ Invalid network ID redirects to scan page ✅ Memory usage within acceptable limits (< 85% flash, < 20% RAM) This implementation fully addresses Issue #10 acceptance criteria with a professional, user-friendly interface for viewing detailed WiFi network information.
