I am trying to connect several bluetooth devices and display the data from each device on one central screen (like a hub). I thought the Magic Mirror Platform might be a good solution, but I can’t seem to understand what exactly is needed to write a complete and successful module for just one bluetooth device. What are the requirements an IoT device in order to get it to communicate and display data through the Magic Mirror?

For example, one device I’m trying to connect is a 3230 Bluetooth Smart Pulse Oximeter from Nonin Meidcal Inc. I am able to see and pair the device with the Raspberry Pi 3 but it has no functionality since I don’t have a program to interact with the device. This is where I was hoping to create a module for the device in order to display its data onto the screen, but again I’m not sure if it’s even possible for this device.

I have a Telehealth Sensor Adaptive Bed Sensor which I want to display data from the device to the mirror’s screen. Normally, the bed sensor would connect to a phone app via bluetooth and record “sessions” for when a patient is occupying and not occupying the bed. When you start a session the app displays a graph with real time data of the sensor recording the pressure applied. While the app is recording the data, it will trigger alerts to the phone about whether the bed is occupied or not. After you stop the recording for that session it saves a log of the data and gives you the option to upload that data. I want to be able to display the real time session and also display the alerts for when the bed is occupied or unoccupied. Below I have provided all of the links that I have for the sensor, the app it normally connects to, and any other documentation that might be helpful. I also have BTLE Profile document for the device, but this forum post won’t let me upload it. It says I don’t have permissions to do so.
