Bluetooth connection optimization method and Bluetooth connection optimization system for embedded system

Abstract

The invention provides a Bluetooth connection optimization method and a Bluetooth connection optimization system for an embedded system. The method comprises the following steps: a user sends an operation instruction to the Bluetooth through an interaction device, the interaction device first feeds back the operation success information to the user after receiving the operation instruction, the interaction device sends the operation instruction to an underlying protocol stack of the Bluetooth at the same time, the underlying protocol stack responds and processes the operation instruction and generates a processing result signal, the processing result signal is sent to the interaction device, the interaction device identifies the processing result signal, if the processing result signal isan operation success signal, the interaction device does not process, and if the processing result signal is an operation failure signal, the interaction device feeds back operation failure information to the user. The Bluetooth connection optimization method and Bluetooth connection optimization system use the protocol to filter user instructions to prevent repeated user instructions from exerting pressure on the protocol stack of the Bluetooth, and at the same time, use a method of feeding back information in advance to achieve the purpose of prompting the user, so as to prevent the user from blindly repeating operations multiple times without receiving feedback information.

Description

technical field [0001] The invention relates to the technical field of wireless transmission, in particular to a Bluetooth connection optimization method for an embedded system. Background technique [0002] Bluetooth is widely used in various embedded devices today, including mobile phones that we often use every day. However, due to the complexity of the Bluetooth protocol itself and the different implementation methods of the Bluetooth protocol stack for each device, there will be a response delay during the connection and operation of the Bluetooth device, especially in the operating environment of the vehicle system. When the Bluetooth is turned on, or when the user continuously clicks the play / pause button, the embedded system will cause a short delay in the system response due to the frequent operation of the Bluetooth, causing the user to feel that the system is stuck. The Bluetooth device still communicates through the serial port, and there are timing problems, an...

However, due to the complexity of the Bluetooth protocol itself and the different implementation methods of the Bluetooth protocol stack for each device, there will be a response delay during the connection and operation of the Bluetooth device, especially in the operating environment of the vehicle system. When the Bluetooth is turned on, or when the user continuously clicks the play / pause button, the embedded system will cause a short delay in the system response due to the frequent operation of the Bluetooth, causing the user to feel that the system is stuck

The Bluetooth device still communicates through the serial port, and there are timing problems, and the user will not consider such problems when operating. Multiple and frequent clicks on the interface will cause confusion in the Bluetooth communication timing. If it is not controlled, it will also cause the bottom layer of Bluetooth to malfunction, resulting in the eventual failure to connect
