I personally has lots of experience with CoreBluetooth. I also did look at the GATT for sometime so I understand how service, characteristics, descriptor works. This note will focus mainly on implementation and how to make Android device work as peripheral and iOS as central to get data transfer from Android to iOS.
This blog will be updated in the future to finish all its contents.

When I was developing the iOS app, sometimes we need different color for an icon asset. For example, if its a button, the normal state or highlight state color is different.
Here is an overview on what I did. Right now at the very beginning, we have the c++ source code file and the iOS Xcode project file. We need to create a new Xcode project and put in c++ source code and compile it and create .a static library. Then put the new project and my iOS Xcode Project in the same workspace. Import the library path and the header path. At this point, the c++ static library is now successfully imported into our existing swift project. The rest we need to do is to call the c++ library inside our swift file.
