AT Command Interface

This repository contains a Python-based AT command interface application with a graphical user interface (GUI) for sending AT commands to a device over a serial connection. It also includes a batch script to easily launch the application.

Features

• GUI for AT Commands: Provides a user-friendly interface for sending AT commands to a device.
• Serial Communication: Establishes a serial connection with the device.
• COM Port Selection: Allows users to select the desired COM port from a list of available ports.
• Device Information: Displays device information, including serial number (DSN) and battery level (if supported by the device).
• Clear Output: Allows users to clear the output display.
• Automatic Centering: The application window is automatically centered on the screen.

Requirements

• Python 3.x: Make sure you have Python 3 installed on your system.
• Tkinter: This is usually included with Python installations.
• pyserial: Install this library using pip install pyserial.
• ADB (Optional): If you want to retrieve device information like serial number and battery level, you'll need to have ADB (Android Debug Bridge) installed and configured.

Usage

1. Install dependencies:

   pip install pyserial

2. Run the application:

   • Execute the start_at_interface.bat batch script. This will check for Python installation and launch the at_cmd_interface.py script.

3. Connect to a device:

   • Select the appropriate COM port from the dropdown menu.
   • Click the "Connect" button.

4. Send AT commands:

   • Type an AT command in the input field (e.g., ATI to get device information).
   • Click the "Send" button.
   • The response from the device will be displayed in the output area.

5. Clear the output:

   • Click the "Clear Output" button to clear the output display area.

6. Disconnect from the device:

   • Click the "Disconnect" button to close the serial connection.
