# 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.
