Is it possible to communicate among devices using bluetooth without pairing from same Xamarin app

I am new to Xamarin development. I wanted to know is it possible to read data using bluetooth among devices without pairing?
I will install Xamarin app on multiple devices. This app will store some data like, user name, email, phone number etc. I want to read this information from another device through bluetooth from same Xamarin app. During this process I don't want to ask user to pair with another device. Because, in a company if there are 100 employees, to communicate between devices among 100, every user need to pair for 99 times. So is there anyway to bypass this option?
