# Bluetooth Lighting

## Do Bluetooth lamps support constant current drivers?

Currently, we are working the SM2135E constant current driver solution and now the PWM-to-constant current solution is supported.

## Can I control a Bluetooth lamp remotely?

Yes, but a Bluetooth gateway is required.

## Is the protocol of Bluetooth mesh smart lighting module standard or Tuya-defined?

Does a Bluetooth lamp support local execution at a scheduled time?

Yes. However, to use the timing feature, a gateway is required.Currently, the smart lighting module uses Tuya protocols.

## Do Bluetooth lamps support the CCT solution?

Yes. When you create a Bluetooth product, select the CCT solution as the color temperature adjustment mode in hardware debug settings.

## Which pins of a Bluetooth CW lamp's CCT firmware adjust the brightness and color temperature?

In a Bluetooth module's CCT firmware, the CW and WW pins are used as the PWM output for brightness adjustment and color temperature control, respectively.

## 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/lighting/untitled-2.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.
