I’m really interested in the Meshtastic project. You do have to buy a physical radio, but it allows you to send encrypted messages over longer distances (and through a mesh network to extend range if there are a lot of devices nearby). I can see it having more utility, despite the upfront costs, than using your phone’s bluetooth.
