Add log cleanup function (15-day deletion) and archive documentation
- Added cleanup_old_logs() function to app_v3_simplified.py - Deletes log.txt if older than 15 days at app startup - Sends notification to monitoring server when cleanup occurs - Archived all legacy modules and documentation to oldcode/ - Updated device_info.txt with correct IP (192.168.1.104) - All changes validated and tested

Headless RFID reader client with batch logging and WiFi recovery
|
||||
|
||||
Main application orchestrator that coordinates system components:
|
||||
- RFID card reader (reads employee badges)
|
||||
- Batch logging with event deduplication (75% network reduction)
|
||||
- WiFi auto-recovery on server disconnection
|
||||
- Remote monitoring via Server_Monitorizare dashboard
|
||||
- Connectivity monitoring and backup data handling
