Here we have a high level data flow architecture for a health care monitoring app. At the low level data is getting captured via sensor mounted upon wearable devices. Sensor collects data and send via Bluetooth communication to connected mobile devices in message queue format. Mobile device further send data to cloud via rest services API and same way get data from cloud via same API.
On the monitoring side we have application written on server side that take decision and send alert as per the business requirement to different devices on web and app as well.
