AR gun bluetooth connection

Hello.. I m new to unity.
I am making my final year project on AR
I want to know that how to add bluetooth connection to my unity app so that I can connect the AR gun to it..
Please.. your answer would be very helpful to me.

 

Look for the Bluetooth arduino microcontroller on the asset store. I was able to connect using an arduino and Bluetooth module. I gutted a nurf gun, put a simple button in behind the trigger for clicks. The hard part is good power source. I used a small portable phone charger to USB on the arduino. Small enough to fit in the clip for darts. All this was done back when tango was still alive.
