# Application ID

TWELIET NET uses 32 bit application IDs to configure different networks for communication on the same physical channel. This means that different application IDs cannot communicate with each other.

{% hint style="info" %}
IEEE802.15.4 uses a 16-bit PAN ID to identify the network, and TWELITE NET also uses the PAN ID mechanism to implement an application ID.
{% endhint %}

## Application ID rules

For the sake of explanation, 32 bits are written as `HHHLLLL`. That is, upper 16 bits are `HHHH` and lower 16 bits are `LLLLL`.

### User configurable values

The addresses specified in this range may be set by other users. In case of duplication, please operate on the premise of coordination between installers.

* HHHH : 0x0001 - 0x7FFF
* LLLL: 0x0001 - 0x7FFF

### Values that can be set by the TWELITE module owner

You can use the ID of your TWELITE module serial number plus 0x80000000 as a non-duplicate address.

* HHHH : 0x8000 - 0x8FFF
* LLLL: 0x0001 - 0xFFFE

## 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://sdk.twelite.info/en/twelite-net-api-expl/paketto/apurikshonid.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.
