Basic Unity Scene with real time connection to one BLE sensor. -- 2

I'm working in Unity game development (very very basic level).
I have a scene that needs to enhance to external 3-axis BLE sensor. I have tried to code but it was not possible to create the enhancement. By now the scene runs with an internal 3-axis sensor but I need to change it to BLE.
I just need this part of the code, to either work on what I already have, or create a very simple scene that allows me to enhance my external sensor. The external sensor is with an Arduino simple send buffer code.
