There was not much information available last time this newsletter covered Amazon Sidewalk. Last week at Amazon’s hardware event, they provided some details about the new service. Sidewalk “uses Bluetooth Low Energy (BLE), the 900 MHz spectrum and other frequencies to simplify new device setup, extend the low-bandwidth working range of devices and help devices stay online and up-to-date, even if they are outside the range of home WiFi.” New Echo devices are capable of acting as a Sidewalk Bridge to extend the working range of connected IoT devices - Amazon Developer Blog
