Hi Seanur,

By definition of advertising in itself is public and everyone can listen to the advertising if they wish to. If you are intending to have more security to your transmittions then you need establish a secure connection with your device.

Can you tell me what specific usecase is in your mind for the above requirement you mentioned?

I see your dilemma, it really seems that the beacon is not the right thing for your usecase. If you really want to find a device (which is attached to your importthing) and no one else can be able to sniff it then the device attached cannot be a beacon it needs to be a master which would be able to direct you towards it securely. Ofcourse there are power consumption limitations to that but I dont see anyway around it.
