Learn how to rapidly prototype Bluetooth Low Energy applications in this first installment of a developer-focused video series. Explore the fundamentals of Bluetooth LE support in nRF Connect SDK, complete the SDK installation process, and begin building IoT applications. Follow along to develop a comprehensive Bluetooth LE application that incorporates both simulated and real sensors, implements wireless data retrieval, handles permanent data storage in non-volatile memory, optimizes power consumption using PPK2, and enables firmware updates over Bluetooth LE (FOTA/DFU). Access accompanying presentation slides and source code through provided GitHub repository to enhance the hands-on learning experience.
