AWS – AWS IoT ExpressLink technical specification v1.3

Today, AWS IoT ExpressLink, a connectivity software that powers a range of hardware modules developed and offered by AWS Partners, announces the release of technical specification v1.3. The updated specification provides hardware manufacturers, who design and develop Internet of Things (IoT) devices, new features for Bluetooth Low Energy (BLE) communication and a new group of commands that give host processors control of the module I/O pins. 

Using the BLE expanded feature set, AWS IoT ExpressLink makes it easier to advertise the devices presence and its capabilities and pair securely with other devices in the local Personal Area Network (PAN). Moreover, the new I/O control commands allow the host processor to use an AWS IoT ExpressLink-powered module as an I/O expander, providing flexible digital and analog input/output capabilities. Combined, these features simplify the development and help reduce the cost of edge devices collecting wirelessly data from low power sensors and communicating with AWS cloud. The new specification has been adopted by AWS Partners, such as Espressif and u-blox towards their Wi-Fi and BLE qualified modules that developers can readily use to build connected products.
