Whoa this is really neat. I’ve been trying to get into Meshtastic but it’s hard to convince others when you need special hardware. Would be super neat if Apple did something similar. Shouldn’t be too hard since the AirTags use the same idea?

Would also be neat if there was a way to build a LoRA proxy to extend the range. I might give this a try with my meshtastic devices.

It'd be cool if Meshtastic's UDP mode could run over BLE like this, for local bluetooth clouds linked by just a few LoRa nodes.

Yeah, a BLE first mesh system honestly makes more sense in today's world since it's baked into every phone. In theory, a BLE to LoRA bridge should be doable with the existing meshtastic hardware like Nordic's nRF52840. The biggest caveat is going to be the data rate. Meshtastic is designed for around 200 bps (Long range mode) which vastly pales the ~2Mbps BLE expectation.
