Usage Guidelines

Usage Scenario

You can run this command to change the transmit power of an AP's built-in Bluetooth module. Increasing transmit power can improve Bluetooth signal transmission quality but causes more severe interference to other wireless devices. Reducing transmit power can reduce interference to other wireless devices but affects Bluetooth signal transmission quality. Configure proper transmit power of an AP's built-in Bluetooth module according to actual situations.

Precautions

After changing the transmit power of an AP's built-in Bluetooth module, you need to run the broadcasting-content command to reconfigure the RSSI calibration value in BLE broadcast frames.

Example

# Configure the transmit power of an AP's built-in Bluetooth module to 2 dBm.
