Solution Overview
Problem
Existing connectivity solutions for IoT devices are cumbersome and error-prone, requiring significant resources and lacking scalability, as they often necessitate custom implementations for each device, failing to meet the demand for modular and cost-effective connectivity across heterogeneous products.
Innovation Solution
A connectivity module architecture that separates connectivity and processing using a standard peripheral interface, such as I²C, SPI, or UART, allowing IoT devices to connect to a wireless network platform and expose a command protocol for device-to-device communication, simplifying the connection process and enabling communication with both IoT devices and cloud services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom connectivity solutions are implemented for each IoT device, then device-specific communication requirements are met, but development resources increase and scalability decreases
Solution Approach 1:
The patent implements a universal connectivity module that can be integrated into multiple types of IoT devices through a standardized host interface. The module contains a wireless network platform and D2D communication framework that can serve different device types (IoT devices, cloud services, peer devices) through the same interface, eliminating the need for custom connectivity solutions for each device type.
Solution Approach 2:
The patent segments the connectivity functionality into a separate modular component (connectivity module with wireless network platform) that interfaces with the host device through a standardized peripheral interface. This separation allows the connectivity logic to be independent from the host device implementation, reducing development complexity while maintaining adaptability.
2Ease of operation
If existing connectivity frameworks are implemented, then communication capability is added to devices, but the implementation process becomes tedious and error-prone
Solution Approach 1:
The connectivity module implements self-service through automatic service discovery and connection establishment mechanisms. The D2D communication framework automatically discovers available services and establishes connections without requiring manual configuration, reducing both the tediousness and error-prone nature of implementation while improving reliability through automated validation.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the connectivity module with a complete D2D communication framework and service registry before deployment. The module comes pre-loaded with communication protocols and connection logic, eliminating the need for error-prone on-site configuration and ensuring reliable implementation across all devices.
3Productivity
If modular connectivity solutions are adopted, then scalability and cost-effectiveness improve, but compatibility with existing MCU/processing designs must be maintained
Solution Approach 1:
The connectivity module is designed with a universal host interface that can communicate with various types of processors (MCU, microprocessor, DSP) through standard peripheral interfaces. This universal interface design allows the same modular connectivity solution to be scaled across different device platforms while maintaining compatibility with existing processor designs.
Solution Approach 2:
The standardized host interface acts as an intermediary between the connectivity module and diverse processor architectures. This intermediary layer abstracts the differences between various MCU/processor designs, allowing the modular connectivity solution to scale across platforms without requiring platform-specific adaptations, thus maintaining both scalability and compatibility.

AI summary
The disclosure relates to an Internet of Things (IoT) connectivity module that can add connectivity to an otherwise non-connected host and simplify procedures to connect, configure, and enable device-to-device (D2D) communication between the host and various heterogeneous IoT devices. For example, according to various aspects, the connectivity module may comprise a connectivity chip configured to implement a wireless network platform (e.g., a radio-frequency front end and one or more wireless radios), one or more standard peripheral interfaces configured to interconnect the connectivity module to a host having at least one processor, and a D2D application configured to implement a proximal D2D communication framework and expose a command protocol associated with the proximal D2D communication framework via the standard peripheral interfaces. Furthermore, according to various aspects, the connectivity module may comprise a dedicated interrupt line that may be asserted to notify the host when data becomes available to consume.
