Resource Filtering for BLE Device Personalities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth Low Energy (BLE) devices lack the ability to efficiently manage multiple device personalities and resources across different wireless connections, leading to software complexity and potential race conditions when configuring services on the fly.
Innovation Solution
Implementing resource filtering using programmable integrated circuits to select and provide specific resources to connecting devices based on connection characteristics such as remote device address, signal strength, and bonding information, allowing multiple services to be supported from a single BLE module without software updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If services are configured on the fly after connection to other wireless devices, then the device can adapt to different connection requirements, but software complexity increases and race conditions may occur
Solution Approach 1:
The patent applies preliminary action by pre-configuring services and resource filters before wireless connections are established. The device determines which services to provide based on pre-defined resource filters that are applied during the connection setup process, rather than configuring services dynamically after connection. This approach maintains adaptability to different connection requirements while significantly reducing software complexity and eliminating race conditions associated with on-the-fly service configuration.
2Adaptability or versatility
If multiple device personalities and services are supported simultaneously, then the device can serve multiple functions across different connections, but resource usage increases
Solution Approach 1:
The patent implements local quality by applying different resource filters to different wireless connections, allowing each connection to receive only the specific services it needs. Instead of loading all possible services into memory simultaneously, the device maintains a pool of service implementations and selectively activates them based on pre-configured resource filters associated with each connection. This enables multiple device personalities to be supported simultaneously while optimizing resource usage by loading only the necessary services for each connection context.
Solution Approach 2:
The patent applies universality by creating a single pool of service implementations that can be shared across multiple wireless connections. The resource filter mechanism allows the same service implementation to be selectively applied to different connections based on pre-configured criteria, enabling one service to serve multiple functions across different device personalities. This reduces overall resource usage compared to maintaining separate service instances for each connection.
3Device complexity
If resource filtering is implemented to select services based on connection characteristics, then software complexity is reduced, but the device requires pre-configuration capabilities
Solution Approach 1:
The patent addresses the pre-configuration requirement by providing mechanisms to define resource filters before device deployment. The system allows service providers to pre-configure which services should be associated with specific connection characteristics (such as device type, connection purpose, or identifier patterns). These pre-configured resource filters are stored in the device and automatically applied during connection setup, reducing the need for complex runtime decision-making while maintaining the ability to adapt to different connection scenarios.

AI summary
Systems and methods are provided that may be implemented to use resource filtering to provide multiple different device personalities and/or multiple different resources from a radio frequency (RF)-enabled wireless device or apparatus to one or more other connecting RF-enabled wireless devices across one or more wireless connections. In one example, each different given resource of a wireless device may be associated with at least one filter which may be used by the device to determine which connection/s the given resource may be provided, and a given resource may only be provided to a given connecting device only if the given resource passes the filter.
