Following a service-oriented architecture, the blood pressure sensor (or any other Bluetooth Low Energy device playing a GATT Server role) exposes some services.
Remember, how we compared Bluetooth Low Energy to a very intelligent database in the previous section, and that is exactly what is happening here. The primary reason for the existence of a blood pressure device sensor (or any other Bluetooth Low Energy sensor/device) is extremely simple. It measures the correct data (blood pressure ...
