I will order the carrying of PhoneGap applications for Android/iOS, which will use the library [url removed, login to view] (or other) and communicate with a blood pressure monitor (GATT profile -[url removed, login to view]) and weight scale (documentation will be send to chosen developer).
Application in the form of JS library that can be attached to another project - calling with the device address and type (pressure monitor; other devices in the future).
We assume that the same bluetooth module is already initialized, therefore we do not check whether we have a bluetooth enabled or not, detection devices, etc., but we bind to a device, read the parameters and call the JS function that will handle the result of the parameters that reads (and the type of device).
The parameters that I want to read:
a) the last pulse measurement,
b) the last measurement of the systolic and diastolic blood pressure,
c) the last body weight,
I do not need any other data (about user, etc.).
