I thought Briar could provide this functionality without any previous pairing using BLE? I don't know too much about BLE but you should be able to just broadcast data without any pairing. Could be encrypted with a pre-shared secret. If the payload is small enough, it shouldn't be that much of a problem. Also Apple Wireless Direct Link is pretty interesting as well. It can do a lot more than Airdrop.
