Project Upgrade to Bluetooth Low Energy

I want to upgrade a project I already have. It uses the bluetooth adapter to connect to an arduino nano. It works well on android 5.1.1, but it no longer works with android 6.0. I read that this is because android 6.0 uses Bluetooth Low Energy in order for it to connect to another bluetooth device. So I need someone to upgrade my project in order for it to use Bluetooth Low Energy, and work with android marshmallow. Before placing a bid, you have to agree that the ownership of the final output of this project will be completely mine. I will leave all the files as attachments. Thanks.
