Solution Overview

Problem

Conventional Bluetooth Low Energy (BLE) modules can only operate in a single mode at a time, limiting their ability to transmit different advertisement packets with varying parameters, which restricts their functionality in applications requiring both long-range non-connectable and short-range connectable communications.

Innovation Solution

Configuring a single BLE radio module with multiple link layers to enable simultaneous transmission of advertisement packets using different advertisement policies, including unique parameters such as packet type, interval, power, and sensitivity levels, allowing the module to transition between modes without reconfiguration and maintain continuous packet transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a BLE module operates in a single mode at a time, then the device complexity is reduced and operation is simplified, but the adaptability and versatility are limited

Engineering Contradiction:
Improveability to transmit different advertisement packetsVSAvoidmultiple link layers configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the single link layer into multiple virtual link layers (first virtual link layer and second virtual link layer), each capable of operating independently with different advertisement policies. This segmentation allows the BLE module to transmit different advertisement packets simultaneously without increasing physical hardware complexity, resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a BLE module transmits different advertisement packets with varying parameters, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improveadvertisement packet transmission capabilityVSAvoidreconfiguration requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements multiple virtual link layers within a single BLE module, where each virtual link layer can operate with different advertisement policies (connectable/non-connectable modes, different intervals, powers, and sensitivity levels). This multi-functionality approach allows the module to handle diverse advertisement requirements without requiring separate physical devices or complex reconfiguration, resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a BLE module transitions between advertisement modes, then the adaptability is improved, but the loss of time occurs during reconfiguration

Engineering Contradiction:
Improvemode switching capabilityVSAvoidreconfiguration time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent pre-configures multiple virtual link layers with different advertisement policies before operation begins. Each virtual link layer is ready to transmit immediately with its designated parameters (connectable/non-connectable modes, intervals, powers, sensitivity levels). When mode switching is needed, the system simply activates the appropriate pre-configured virtual link layer, eliminating reconfiguration time and resolving the contradiction between adaptability and time loss.

Inventive Principle:
Principle #10Preliminary action

AI summary

Systems and methods that may be implemented to configure a single common radio frequency (RF) radio module with multiple link layers to allow the radio module to transmit different advertisement packets at the same time using different advertisement configuration parameters. A radio module may be simultaneously configured with the multiple link layers to allow the radio module to operate using unique different advertisement parameters corresponding to each of multiple different advertisement policies, and such that the radio module may selectively transmit advertisement packets in real time using any one of the different advertisement policies.
