Description

A function setting method and device based on bluetooth protocol

technical field

The invention relates to the field of communication technology, in particular to a function setting method and device based on the bluetooth protocol.

Background technique

At present, most mobile terminal platforms such as the International Organization for Standardization (ISO) platform or the Android platform can be connected to Bluetooth headsets or car Bluetooth devices. After connecting the Bluetooth headset or car Bluetooth devices, if the mobile terminal platform has a phone , the call sound of the opposite end will be transmitted to the Bluetooth headset or the car Bluetooth device for playback through the Bluetooth connection, and the local sound input is input by the microphone of the Bluetooth headset or the car Bluetooth device.

Under normal circumstances, after the Bluetooth headset or car Bluetooth device records local sound, it will perform echo cancellation and noise reduction processing on the recorded local sound. If the Bluetooth headset or car Bluetooth device does not have echo cancellation and noise reduction processing capabilities, the mobile terminal platform Echo cancellation and noise reduction can also be performed on local sounds received from Bluetooth headsets or car Bluetooth devices. Most Bluetooth headsets/vehicle Bluetooth devices have echo cancellation and noise reduction functions. In this way, during the actual call, after the Bluetooth headset or car Bluetooth device has performed echo cancellation and noise reduction processing on the local sound, the mobile terminal platform will not respond to the local sound. The sound undergoes the second echo cancellation and noise reduction processing, which will cause noise and low volume of the local voice, which means that the peer end hears the local voice with noise and low volume.
