This article explores various network provisioning methods for embedded devices—including SmartConfig, SoftAP, Combo, NFC, and acoustic techniques—covers essential Wi‑Fi concepts and terminology, and provides a hands‑on guide to implementing SmartLink on Linux with code examples and packet analysis.
This article examines five Wi‑Fi provisioning techniques—AirKiss, SmartConfig, hotspot, Bluetooth, and QR‑code scanning—detailing their processes, technical principles, advantages, and drawbacks, and proposes an enhanced hotspot solution to improve success rates and simplify setup for IoT devices lacking screens or cameras.
The article surveys IoT architecture and Wi‑Fi’s role as the primary connectivity layer, then details six Wi‑Fi provisioning techniques—direct UART/SPI, WPS, web‑based AP, SoftAP, SmartConfig/SmartConnection, and sound‑wave—comparing their advantages, limitations, and suitability for different product, cost, and environmental constraints.
