<details>

<summary><strong>What is the maximum number of simultaneous TCP clients?</strong></summary>

The Enless LoRaWAN gateway behaves like a server and can accept only one client at a time. Being queried by another Modbus device may disrupt Modbus communication with the current TCP client.

<summary><strong>How do I create a third-party sensor profile?</strong></summary>

**1. Start from existing Codecs and Mappings**

See the page <i class="fa-code" style="color:$primary;">:code:</i> [Third-party sensor decoders](https://enless.gitbook.io/centre-aide/ressources/gateway-lorawan/decodeurs-capteurs-tiers) to access the list of sensors for which decoders are already available.

**2. Develop the Codec and the Mapping yourself**

See the page [Codec and Mapping tutorial](/centre-aide/ressources/ressources-en/lorawan-gateway/codec-and-mapping-tutorial.md) in the section **Resources** to learn how to integrate a new sensor by configuring its decoding script and its JSON mapping table.

Finish creating the profile with the **Add**.

{% hint style="warning" %}
A **third-party sensor profile** cannot be **deleted** if it is used by one or more **devices** **active** ; you must **absolutely** **delete** all **sensors** **associated** with this profile in the **TX CONFIG** before you can remove the profile from your library.
{% endhint %}

<details>

<summary><strong>Is it possible to use the RX REPEATER 600-301 repeater with the LoRaWAN gateway?</strong></summary>

No, the RX REPEATER 600-301 signal repeater is a LoRa Easy repeater (proprietary LoRa); it can only be used when Enless sensors communicate with an Enless LoRa Easy receiver.&#x20;

## 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/troubleshooting.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.
