Bluetooth sensors dashboard in Unity3D

Hello, I need to develop a mobile app (iOS/Android) that read realtime data from 4 sensors and show them into a dashboard on phone's display. We only need to receive 3 inputs with SPP values For the SPP profile to work the application have to integrate something like this: 1) when application starts, it will scan for bluetooth devices. 2) then it connects with the Bluetooth device and show a confirmation of the pairing . 3) then received the data on SPP profile and displays something on the screen to show it is receiving input. Sensors are currently SPP devices, but we can setup data communication as requested, so the project is open to advices and suggestions.
