If the nodes have GPS it's fairly straightforward to calculate distance and bearing.

Right, and accuracy of ~9m makes sense for this application. The smaller supported ESP32's, however, don't have onboard GPS. Does it use RSSI or need to be paired with a phone?

Not that it's really relevant here, but I'm wondering if the LORA RSSI can be used to determine distance inside 9m.
