In the context of app development, this is typically a BLE device you’re working with, like a heart rate monitor.Ī collection of characteristics (data fields) that describes a feature of a device, e.g. In the context of app development, this is typically an Android device.Ī device that advertises its presence and is connected to by a central in order to accomplish some task. We kick things off by listing some keywords that you’ll come across when getting started with BLE development on Android.īluetooth Low Energy, a subset of the 2.4 GHz Bluetooth wireless technology that specializes in low power and oftentimes infrequent data transmissions for connected devices.Ī device that scans for and connects to BLE peripherals in order to perform some operation. The actual, full implementation in the context of an example app is available as an open source GitHub repo. Most code snippets were written in Kotlin, but they translate well over to Java too.Īll the code snippets in this post aim to showcase how a given BLE operation should be performed.

In this post, we’ll go over the basics of BLE that Android developers need to know, as well as walk through some simple yet real-world examples of performing common BLE operations on Android like scanning, connecting, reading, writing and setting up indications or notifications. Unfortunately, the Android SDK’s BLE API is full of undocumented pitfalls and leaves a lot to be desired despite the platform commanding over 76% of market share worldwide.įret not, as the Punch Through team has learned a lot over the years working on BLE connected Android apps, and we’re here to share our experiences and lessons we’ve learned with our readers!įor new readers not familiar with who we are and what we do, we are Punch Through: an engineering consulting firm specializing in firmware, software mobile, and hardware solutions that help engineering leaders and teams through the complex journey of building a Bluetooth product. With its ability to consume very little power yet still provide the connectivity to communicate with small devices, more and more people are looking to hop on the Bluetooth Low Energy (BLE) bandwagon for Android apps.
