Have you looked at Bluetooth LE Long Range? I believe more recent phones have it and it claims communication of up to 1km. In practice less in the woods I'm sure. Still a dramatic win over standard Bluetooth though.<p><a href="https://novelbits.io/bluetooth-long-range-coded-phy/" rel="nofollow">https://novelbits.io/bluetooth-long-range-coded-phy/</a>

Cool idea, but doesn't Meshtastic already do this but with better range because it uses radio instead of BT?

This is awesome! Does it have an alert feature? I'm also curious about battery life.

Super cool idea! This would be amazing for Airsoft games

Very cool idea. What's the range of BLE connectivity? I can't imagine it gets far

Isnt the range of Bluetooth pretty much the range of a loud yell?
