Posted in Embedded Development & Programming

Summary

DMC undertook an internal R&D project to explore the capabilities of Amazon Sidewalk using Quectel’s KG100S module. 

Amazon Sidewalk is a secure, community-based network that leverages devices like Echo and Ring to extend wireless coverage beyond typical home Wi-Fi ranges. Designed for ultra-low-power, low-bandwidth communications, Amazon Sidewalk targets the IoT applications that demand reliable connectivity without the cost or power demands of cellular technology. 

DMC’s work demonstrated how combining Sidewalk with advanced sensor arrays, GPS tracking, and efficient firmware architecture can deliver robust, battery-friendly IoT solutions.   

Solution

DMC’s custom evaluation board combines the Quectel KG100S module, GPS, and multiple sensors, along with storage and interface expansions, into a single compact platform. The firmware leverages standard Amazon Sidewalk examples for sub-GHz connectivity, augmented by DMC’s custom drivers for sensor acquisition, GPS data parsing, and data compression.  

Provisioning each device securely registers it on the Sidewalk network, a process fully automated in the Docker-based build system.  

By buffering sensor readings locally and transmitting only essential, compressed data, the solution optimizes bandwidth usage while delivering extended battery life 

A custom Amazon AWS-based application was also developed to ingest and visualize the data received from the sensors. 

Overall, this evaluation system demonstrates the practicality of low-power, long-range IoT devices using Amazon Sidewalk.
