Android is the perfect platform for hacking with Bluetooth peripherals. Learning how to connect to BLE devices is not only a useful skill for professional developers, it’s also massive fun! Recent releases of Android have improved how BLE interaction works, and this session takes you through the latest Android 14.

It's built around a capture-the-flag competition: the first person to write an app to read my password, wins!

Learn:

- How to write code to send and receive messages from an Android device to any BLE peripheral
- How Android communicates with a BLE device
- All about BLE - how it works and what makes it different to Bluetooth Classic.

And when you get back home you’ll want to try out connecting with all the BLE devices you have lying around! Heart rate monitors, thermometers, proximity sensors, lights, radios, TVs, keyboards, garage doors, …

A very basic understanding of Android development is required. People will need a laptop with Android Studio and, if they want to join the competition, a physical Android device (not VM). I will bring a limited number of devices with me for those who don't have their own.
