Release v2.2 ✨

⚡ Improvements

• readData Function

  • The delay function has been removed, making data reading much faster and more reliable.
  • After sending data, the readData function now checks if data has arrived for 1 second. If data arrives and is fully read, it exits immediately.

• Echo Handling

  • A new function has been added to remove echo of sent data.
  • This results in faster reading and a cleaner codebase.

• writeData Function

  • The writeData function has been streamlined. Instead of passing an entire array of data, you now only need to specify which mode and data to retrieve.
  • One function now handles both live data and freeze frame.

✨ New Features

• Connection Loss Detection

  • After calling writeData, if 3 consecutive attempts to receive data via readData fail, the system detects the connection has been lost.
  • In such cases, the system will attempt to reinitialize the connection.

• 5 Baud Init Function

  • A new function allows you to initialize modules at 5 Baud by simply providing the module address.
  • The function automatically performs the 5 Baud Init process for the given address.

• WebServer Enhancements

  • Serial commands have been added for easier monitoring.
  • If an ESP32 with two or more UARTs is used, you can now track processes via Serial Monitor.
  • WebServer Page 4 now includes a status box, showing whether the device is connected or not and displaying the speed directly if connected.

🛠️ Fixes

• Freeze Frame Reading Error
  • The error that occurred during freeze frame reading has been fixed.

🎯 Result:
With these updates, the system is now faster, more stable, and more organized! 🚀
