# Sidebar

Present on all pages of the interface, the left sidebar is your permanent dashboard. It allows quick diagnosis of the state of the *gateway* and the quality of the radio network.

**MAC** : Unique identifier of the network card of the g*ateway* (useful for static DHCP addressing or asset inventory).

**Modbus** : Displays the active communication mode among the three possible options:

* RTU RS485: RS485 serial link only.
* TCP/IP: Ethernet network link only.
* TCP/IP + RTU RS485: Both interfaces are active simultaneously.

**Software version** : Current version of the installed firmware.

**Active sensors** : Total number of sensors that have recently transmitted data.

**Average RSSI** : Average received signal strength ($$dBm$$). The closer the value is to 0, the stronger the signal (e.g., -70 $$dBm$$ is excellent, -130 $$dBm$$ is weak).

**Average SNR** : Average Signal-to-Noise Ratio ($$dB$$). Indicates the clarity of the signal relative to ambient interference. A positive value indicates very stable reception.

**Date and time** : Current system timestamp

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://enless.gitbook.io/centre-aide/guides-installation/documentation-en/products/rx-lorawan/configuration/sidebar.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
