The most significant change is the incorporation of the necessary algorithm so that each medical measurement device can perform the interpretation and management of data without the need to be connected to the internet, that is, each device can evaluate the data autonomously.
You can communicate with a mobile device via Bluetooth or via Wi-Fi with the central system to store the results obtained and incorporate them into a database and thus attach them to the patient's history in order to give a complete diagnosis by your doctor of family.
The other functionalities of these devices have not changed with respect to the other monitoring and security devices, that is, the acquisition and interpretation of data uses the same technology.
