Bluetooth 5.4, Bluetooth 6, LE Audio, Auracast and IoT Applications
Why this Bluetooth / BLE course?
This intensive two-day course provides a practical introduction to modern Bluetooth wireless technology, with particular emphasis on Bluetooth Low Energy (BLE), Bluetooth 5.4 and important Bluetooth 6.x capabilities.
Delegates will learn how Bluetooth systems are structured, how devices communicate, and how to make informed architecture, application-design and troubleshooting decisions for Bluetooth-enabled products. The course covers core protocols, application development concepts, security, performance optimisation, and the latest developments including LE Audio, Auracast, Bluetooth Mesh and IoT ecosystems.
The course combines technical theory with practical examples and real-world engineering considerations.
