AWS IoT ExpressLink Technical Specification v1.3 Released

🔧 AWS IoT ExpressLink technical specification v1.3 introduces expanded Bluetooth Low Energy (BLE) capabilities and a new set of I/O control commands that enable host processors to manage module pins. The BLE enhancements make it easier for devices to advertise presence and capabilities and to pair securely within a local Personal Area Network (PAN). The I/O control commands allow an ExpressLink-powered module to act as a flexible digital and analog I/O expander. AWS Partners including Espressif and u‑blox have adopted the update for their Wi‑Fi and BLE qualified modules.
