# BLE Mesh Lighting Solution

## How many devices does a Sigmesh gateway support?

The number is 64. This is because some information needs to be stored on the Wi-Fi gateway, and the amount of Wi-Fi side storage is limited.

## For Sigmesh products, when clicking into the music mode, the light just shows white light and does not have changes when recognizing the sound, Why?

Maybe the microphone is not called, so the music data cannot be sent. Music mode needs to be operated under the music panel.

## Why the command of adjusting white brightness is not issued in real time, it only takes effect after the finger leaves the interface?

It is because the amount of data sent in real time will be very large, the SigMesh network itself has a slow propagation rate, which is not suitable for real-time data transmission.

## 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://docs.ifreeq.com/faqs/smart-product-solution/ble-mesh-typical-solution/ble-mesh-lighting-solution.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.
