A side note, airtags + iphones are effectively the largest bluetooth mesh network in the world, and they are quite useful even though only coordinates are sent.
If the goal is transmitting a message how do coordinates from a "read-only" device facilitate a p2p transfer?
Imagine one just as large as the airtag + iphone ecosystem but with messaging capabilities!
Would be cool to see one built into android + iphones but that will never happen. But a 3rd party could get so popular that it achieves somewhat close to that.
I'd imagine remote villages and towns could all install this and communicate with each community member very effectively.
