ChatterBox Off-Grid Updated Instant / Secure Send Demo

This is an updated demo of instant delivery (rather than mesh). It demonstrates the speed of message sending and acknowledgement, as well as how a user would send messages.
You can read more about the ChatterBox project at chatters.io.
ChatterBox is a mesh-capable LoRa messaging system that does not use internet, cell service, or any kind of service. Instead, messages are delivered through the air, either directly to the other ChatterBox, or can hop across several ChatterBoxes to reach their destination (theoretical limit of 89 hops). The longest single-hop distance I've tested so far (with different antennas than shown here) is 7+ miles. So, you could imagine the distance between the green and pink ChatterBox could be over 20 miles, and the test should produce the same result.
