Bluetooth Low Energy has become one of the most widely used wireless technologies in modern mobile applications. It powers wearables, fitness trackers, medical devices, smart home products, industrial sensors, asset tracking solutions, and countless Internet of Things devices.
In this course you'll learn how Bluetooth Low Energy works by building real applications using Kotlin, Jetpack Compose, and Android's Bluetooth LE APIs.
Rather than focusing only on API calls, the course begins with the underlying concepts that every Bluetooth developer should understand. You'll learn how the Bluetooth protocol stack is organized, how devices discover one another, how GATT is structured, how data is exchanged, and how BLE communication differs from traditional networking.
Once the fundamentals are in place, you'll build increasingly capable applications that implement both the Central and Peripheral roles. Along the way you'll learn how to scan for nearby devices, establish and manage connections, discover Services and Characteristics, read and write Characteristics, receive Notifications and Indications, decode advertisement data, work with connectionless communication, develop beacon-based solutions, transfer data efficiently, and troubleshoot common Bluetooth issues on Android.
Every major topic includes practical demonstrations, downloadable source code, and quizzes to reinforce the concepts you've learned.
By the end of the course you'll have a solid understanding of Bluetooth Low Energy and the confidence to build your own BLE-enabled applications for Android.
