Hi,
I've been working on a master's thesis about integrating IoT medical devices and am now in the end of it. During the thesis I've developed a proof-of-concept that consists of a web service and an Android application acting as a gateway between personal health devices and the web service.
The Android application that uses the Antidote library to receive measurement data from PHDs and therefore I thought it could be a good idea to post a link here for reference.
The application only supports pulse oximeters as of now, because the tested PHD was a pulse oximeter, but extending it shouldn't take much time or effort.
