MVSHarp Version -  how to get UUID of other instruments

Hi all, 
I am using the .NET version of this library. I have tried to run the examples but do not understand how they get the UUID for thermometer and heart monitor. So I have a bluetooth ble calliper and bluegiga bluetooth dongle and I am trying to establish connection between the calliper and dongle so that I can retrieve data from the calliper.

Please help.

Thanks.
