BLE-Assisted Wi-Fi Direct Pairing for Cross-Platform Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The pairing request from a cellphone side in a Windows environment to an Android device using Wi-Fi direct often results in pairing failures or long waiting times, negatively impacting user experience.
Innovation Solution
Establish a Bluetooth Low Energy (BLE) connection between a mobile device and an electronic device, transmit connection information, and use the mobile device to initiate a Wi-Fi direct pairing request, followed by the electronic device canceling the initial request and sending a subsequent pairing request to establish a successful Wi-Fi direct connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pairing request is transmitted from the cellphone side in a Windows environment to an Android device using Wi-Fi direct, then the connection establishment should be initiated by the mobile device, but pairing failures or long waiting times occur
Solution Approach 1:
The patent introduces a Windows service as an intermediary component that mediates between the mobile device and the Android device. This service intercepts the pairing requests, obtains the necessary connection information through BLE, and facilitates the Wi-Fi direct connection establishment, thereby resolving the pairing failures and long waiting times that occur when the cellphone directly initiates pairing in a Windows environment
Solution Approach 2:
The patent performs preliminary actions by establishing a BLE connection before the Wi-Fi direct pairing process. The Windows service obtains the connection information (such as MAC addresses) through BLE in advance, so that when the pairing request is processed, the necessary information is already available, eliminating the need for lengthy waiting periods and preventing pairing failures
2Reliability
If the pairing request is transmitted from the computer side to the cell phone side, then pairing success is achieved, but user experience is negatively affected due to manual intervention requirements
Solution Approach 1:
The patent implements self-service by enabling the mobile device to automatically obtain connection information through the BLE connection established by the Windows service. The system automatically processes the pairing requests and establishes Wi-Fi direct connections without requiring manual user intervention to input MAC addresses or configure connection parameters, thereby improving ease of operation while maintaining high pairing success rates
