Overview:
This project combines an Android chat app with an ESP32-based LoRa module to enable the wireless transmission of short messages. The Android app provides a user-friendly interface for sending and receiving messages, while the LoRa module facilitates long-range communication between the app and physical devices.

Workflow:
1. Android app establishes USB-Serial connection with ESP32 module.
2. Messages are sent from the app to the ESP32 module via USB-Serial.
3. ESP32 module transmits the messages wirelessly using LoRa.
4. Received messages are forwarded from the ESP32 module to the recipient's app via USB-Serial.
5. Messages are displayed to the recipient.

Benefits:
- Long-range communication capability
- Low power consumption for extended device operation
- Internet-independent communication

This project enables wireless short message transmission by integrating an Android chat app with an ESP32-based LoRa module, offering users a convenient way to communicate over long distances without relying on internet connectivity.
