Bluetooth Auto-Pairing via Advertising Packets

Solution Overview

Problem

Conventional Bluetooth pairing procedures are time-consuming and require users to have a comprehensive understanding of the user interface, causing inconvenience, especially for elderly individuals, those with poor sight, or those with difficulty in finger manipulations.

Innovation Solution

A wireless communication system that includes a source and destination wireless device with specific Bluetooth communication circuits, packet generating and parsing circuits, and control circuits to automatically insert and parse auto-pairing requests and device addresses in advertising packets, enabling automatic Bluetooth pairing without user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional Bluetooth pairing procedure is used, then user can establish Bluetooth bond, but user must conduct several manipulation steps consuming considerable time

Engineering Contradiction:

Improvepairing speedVSAvoidpairing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The source wireless device performs preliminary actions by proactively transmitting advertising packets containing auto-pairing requests and source Bluetooth device addresses before the destination device needs to pair. This eliminates the need for the user to manually scan and select devices, as the pairing information is already prepared and transmitted in advance.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements self-service pairing where the wireless devices automatically handle the pairing process without user intervention. The source device automatically transmits advertising packets with pairing requests, and the destination device automatically receives and processes these packets to establish Bluetooth bonds, making the system serve itself rather than requiring manual user operations.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If conventional Bluetooth pairing procedure is used, then user can establish Bluetooth bond, but user must have comprehensive understanding of user interface

Engineering Contradiction:

Improveuser interface complexityVSAvoidpairing mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the complex pairing mechanism from the user interface by implementing automatic pairing at the device level. The source wireless device automatically generates and transmits advertising packets with pairing requests, while the destination device automatically processes these packets. This removes the need for users to understand or interact with complex user interface elements for pairing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The advertising packets serve as an intermediary carrier that automatically conveys pairing information between devices. Instead of requiring direct user interaction with complex interfaces, the system uses these intermediary packets to automatically transmit source Bluetooth device addresses and auto-pairing requests, simplifying the user experience while maintaining the necessary pairing functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If conventional Bluetooth pairing procedure is used, then user can establish Bluetooth bond, but causes great inconvenience to elderly, people with poor sight, or people having difficulty in finger manipulations

Engineering Contradiction:

Improveuser manipulation difficultyVSAvoidpairing time

AI summary

A wireless communication system and related wireless devices are disclosed. The wireless communication system includes: a source wireless device configured to operably insert an auto-pairing request and one or more source Bluetooth device addresses into one or more predetermined advertising packets to form one or more target advertising packets, and configured to operably transmit the target advertising packets; and a destination wireless device configured to operably receive and parser the target advertising packets to extract the auto-pairing request and the one or more source Bluetooth device addresses. The destination wireless device performs an auto-pairing procedure with the source wireless device according to the auto-pairing request and the one or more source Bluetooth device addresses to establish a Bluetooth bond with the source wireless device. Each of the predetermined advertising packets is an advertising indication (ADV_IND) packet, a non-connectable advertising indication (ADV_NONCONN_IND) packet, or a discoverable advertisement indication (ADV_DISCOVER_IND) packet.
