Develop STM32-to-ESP8266 WiFi connectivity from the ground up, including drivers, buffering data structures, web clients, remote control servers, and cloud storage. WiFi connectivity lets embedded devices interact with web APIs, remote users, and cloud storage without relying on heavyweight platforms. This course focuses on bare-metal STM32 development with the ESP8266, giving learners control over the drivers and communication layers behind connected firmware. The learning path begins with development setup, bare-metal context, GPIO testing, networking concepts, and the WiFi protocol. Learners build debug UART and ESP UART drivers, system timebase support, FIFO and circular buffer structures, ESP8266 WiFi connection libraries, and final projects for weather APIs, remote hardware control, and cloud-based sensor-data storage. By constructing the connectivity stack step by step, learners understand how data moves between the microcontroller, WiFi chip, and internet services. The project sequence builds confidence in practical IoT communication; by the end of this course, learners can create STM32 WiFi firmware that supports web clients, servers, and cloud-connected sensor workflows. Embedded firmware developers, IoT learners, and STM32 programmers who want to connect devices to the internet using ESP8266. Useful for those interested in bare-metal WiFi drivers, UART communication, buffering strategies, web APIs, remote control, and cloud sensor-data storage. The course begins with networking concepts before building the STM32 and ESP8266 driver layer. Data structures are introduced when communication management requires them. Final projects combine the library with web API access, remote hardware control, and cloud storage. This course is based on Embedded Wifi Bare-Metal Development From Ground Up™, by Israel Gbati.
