This chapter will be the conclusion of the journey which we started six chapters back. We will be covering the following topics in this chapter to enhance your knowledge about Bluetooth 5, which is the latest release by the Bluetooth Special Interest Group (SIG):

• Bluetooth 5
• Practical Use Cases
• Future of BLE
• Future of IoT

Moving further in this chapter, we will be introducing various practical use cases of IoT built using Bluetooth Low Energy, which are already being used by people in their day-to-day lives. These cases will give you a bird's-eye view of Bluetooth Low Energy applications with respect to IoT in different domains.

Eventually, we will discuss what the future holds for BLE and IoT, and we shall conclude by consolidating what we have learned so far.
