I have a sensor and a Bluetooth dongle( HC 05) with SPP protocol. We have to connect the sensor to the PC via Bluetooth in which we made our game in unity 3D. The problem now is i have to write a program for the Bluetooth so that 1)unity search for the sensor ( the sensor will be having a mac address and we will be having 5 sensors, other than those 5 sensors it will not allow any other sensor to be paired with, it will reject the pairing). 2) after searching for the sensor it will start pairing with PC in which our unity is installed. i have to write Bluetooth programming, i only know a little bit of C language only. I tried searching online but the programming is for Bluetooth API for android only. I am new to this problem, so please help me from the basics. It would be of great help. Thank you.

What I have tried:

i tried searching everywhere but the codes i found were of the android Bluetooth API and i have little knowledge of this , so i need to start it from the beginning. how should i do that?

I'd start with this: Bluetooth Framework and RFCOMM Protocol[^] and this: Transferring files and monitoring bluetooth ports in C#[^]

This might be useful too:
Bluetooth SPP[^]
c# - Universal Application + Bluetooth + SPP - Stack Overflow[^]

so, i should start from knowing how Bluetooth works and then write the code in C# for sending and receiving files from sensor and PC?
