In the last chapter, we configured our systems so that we could build apps to gain a better understanding of Bluetooth Low Energy. In this chapter, we will build a Service Explorer app using which you can explore all kinds of Bluetooth Low Energy devices for their services. Also, as a bonus, we will simulate our very own homemade fitness tracker and explore its services and characteristics using the same app.
We hope that you remember our discussions regarding Bluetooth Low Energy architecture from the first chapter. Even if our deep discussions in the last chapter regarding the setup of our development environment has made it a little foggy, worry not, as we start with a refresher of the BLE architecture concepts in this chapter.
We will be creating a Service Explorer App by covering the following topics in this chapter:
- Central Peripheral Architecture for BLE
- Services and Characteristics
- Creating a Service Explorer App
