Garmin GMR18 Radome Control Tool

This tool offers a simple interface for interacting with the Garmin GMR18 Radome, enabling both local and MQTT-based remote control and configuration. It is designed to provide real-time control and status updates for the radar, including power management, range setting, gain adjustment, and more.

Requirements Python 3.6+ asyncio for asynchronous I/O socket and struct for network communication json for data serialization paho-mqtt Python client library for MQTT communication

Features

• Power Control: Switch the radar power on or off.
• Range Adjustment: Modify the radar's scanning range.
• Gain Management: Set the radar's gain manually or to auto-adjust.
• FTC and Crosstalk Management: Enable or disable Fast Target Tracking (FTC) and Crosstalk.
• MQTT Integration: Remotely control the radar and receive status updates via MQTT, enabling integration with automation systems or custom interfaces.
• Real-Time Data Publishing: Stream scanline data and radar status updates in real-time over MQTT for external monitoring and analysis.

Requirements

• Python 3.6 or newer.
• asyncio for asynchronous operations.
• socket and struct for networking.
• json for data serialization.
• paho-mqtt for MQTT communication.

Configuration

Network Settings: Configure local_address, remote_address, and multicast_address according to your network setup and radar unit.

• MQTT Settings: Set mqtt_broker and mqtt_port to your MQTT broker's address and port.

MQTT Topics:

• Commands are received on: garmin/radar/command

• Scanline data is published to: garmin/gmr18radar/scanline

• Status updates are published to: garmin/gmr18radar/status

• Issue commands through the command-line interface or by publishing to the garmin/radar/command MQTT topic.

• MQTT Command Structure: Commands should be in JSON format, for example:

  `{
    "action": "set_range",
    "value": 1.00
  }`
  

Supported actions include power_on, power_off, set_range, set_gain, among others, as detailed in the script.
