In this chapter, we had an overview of how to use the Estimote SDK using SWIFT. The API works in collaboration with Estimote Cloud and can be used to request and push data. Using the information given in this chapter, you can easily implement your own apps. As of now, Estimote only supports iOS and can only be used by iPhone 4S+, but soon, it will be available for Android as well. In the coming chapter, we will study the theoretical and practical aspects of Bluetooth Mesh technology with the help of CSRMesh.
