# Zigbee General Solution

## How long will the module take to get into sleep mode after the low-power Zigbee general firmware communication ends?

After the uart communication is over, the Zigbee module will get into sleep mode after 100mS. The MCU need to pull low the wake-up pin 10mS before the next communication.

## Does a Zigbee module have heartbeat packets?

No.

## How many scenes and groups does a single Zigbee device support simultaneously?

A single Zigbee device simultaneously supports up to 56 scenes and groups in total.

## Why i cannot control the Zigbee scene switch using the MCU solution?

DP 17 has to be selected and used to report the data to control the Zigbee scene switch.

## What is the protocol version of Tuya Zigbee?

Tuya Zigbee is developed based on Zigbee 3.0.

## 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/device-development/mcu-access-mode/zigbee-general-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.
