MT5700M PHY AT ETH Control

This is a Python script that provides a command-line interface for managing and interacting with a 5G cellular module. It allows you to perform various operations such as viewing signal strength, locking/unlocking cells, restarting the cellular module, and executing custom AT commands.

Change Log

2024/12/09 Version 1.0.0, Add 5G Scan Cell

2024/12/14 Version 1.0.1, Repair ats processing logic to enable reconnection,set the return result function to make the return result clearer

Features

• View 5G NR and LTE carrier Aomponent status
• View signal strength and quality
• Check lock status and lock/unlock cells
• Restart the cellular module
• Execute custom AT commands
• Perform initial configuration for cell scanning
• Scan for available cells and display detailed information

Currently includes the following features:

1. 📈 5G NR CC Status
2. 📶 View Signal
3. 🔒 Lock Status
4. 🔍 Scan Cell
5. 🔋 Restart Cellular
6. 🖥️ Other Command
7. ⏹ Exit

Prerequisites

1. First, make sure that the MT5700N-CN AT network port is open (need to be implemented through the serial port, type-c to serial port):

AT^TDPCIELANCFG=2
AT^TDPMCFG=1,0,0,0
AT+CGDCONT=8,"IPV4V6"
AT^SETAUTODIAL=1,2 # Auto dial, send in USB connection mode

2. The default IP address of MT5700N-CN is 192.168.8.1, and the port is 20249. Make sure that the 192.168.8.1 address can be pinged, and the corresponding network port can be accessed by telnet.

3. Install the following prerequisites:

• Python 3.x
• tabulate library (install with pip3 install -r requirements.txt)

Usage

1. Run the at server program on the Linux host:

python3 ats.py

2. Run the at client program on the Linux host:

python3 at.py

Configuration

The script uses the following configuration values:

• SERVER_IP: The IP address of the server (default: "192.168.8.1")
• SERVER_PORT: The port number of the server (default: 20249)
• BUFFER_SIZE: The buffer size for receiving data (default: 2048 * 4)
• RETRY_DELAY: The delay (in seconds) between connection retry attempts (default: 3)
• SOCKET_FILE: The path to the Unix Domain Socket file (default: "/tmp/at_socket.sock")

You can modify these values in the script if needed.
