Many of the classes use Bleak objects as their base classes. Functionally this works find. However, bleak uses these classes to encapsulate characteristics and services that were already created by some discovered peripheral. In this case, where we are creating the peripheral, these objects are not yet instantiated. Separating out the logic for defining the attributes for characteristics and services from their instantiation within the app-service-characteristic tree would make the implementation more intuitive and allow for better unit testing.
