Bluetooth Extended Inquiry Response Device Name Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Bluetooth pairing process is time-consuming due to the need for a terminal to send a remote name request to obtain a Bluetooth device's device name, which delays the pairing process.
Innovation Solution
The method involves a Bluetooth device returning an extended inquiry response (EIR) carrying its device name and supported features after receiving an inquiry request from a terminal, allowing the terminal to quickly display the device name and complete pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the terminal sends a remote name request to obtain the Bluetooth device's device name, then the terminal can display the device name, but the pairing process takes more time
Solution Approach 1:
The Bluetooth device includes the device name in the extended inquiry response packet that is sent during the initial inquiry phase, before the terminal needs to request it. This preliminary inclusion of information eliminates the need for a separate remote name request and response exchange, thereby reducing the overall pairing time while ensuring the terminal has the device name information ready for display.
2Device complexity
If the Bluetooth device returns only basic inquiry response, then the response is simple, but the terminal cannot obtain device name and feature information quickly
Solution Approach 1:
The patent merges the device name information and feature information into the extended inquiry response packet that is already part of the standard Bluetooth inquiry procedure. By combining multiple pieces of information (device name, features) into a single response packet that is exchanged during the initial inquiry phase, the patent avoids multiple separate request-response cycles, thereby improving pairing speed without significantly increasing the complexity of the response structure.

AI summary
This application relates to the field of short-range wireless communication technologies, and discloses a Bluetooth pairing method. The method includes: when a terminal receives a first operation of a user, the terminal sends an inquiry request to a Bluetooth device, where the inquiry request is used to obtain a Bluetooth address of the Bluetooth device. When receiving the inquiry request, the Bluetooth device sends an inquiry response to the terminal, where the inquiry response includes the Bluetooth address of the Bluetooth device. The Bluetooth device sends an extended inquiry response to the terminal, where the extended inquiry response includes a device name of the Bluetooth device. After receiving the extended inquiry response, the terminal displays the device name of the Bluetooth device. In this way, the terminal can quickly display the device name of the Bluetooth device, thereby reducing a time consumed by the terminal in a process from discovering the Bluetooth device to pairing with the Bluetooth device.
