Is anyone fucking around with LoRa for comms?

I’ve built a little meshtastic LoRA node and tested sending messages with a friend . Was pretty easy. Haven’t had a chance to anything more with it.

At one point I was broadcasting the bitcoin header chain over Lora…you could get it anywhere in Manhattan, basically…. Sadly that range is just short enough to not be super useful.

LoRa meshes might fix this.

At very high density and with repeaters, but iiuc mesh is more about individual message routing, not broadcasting something that’s a constant stream. Sadly bandwidth just isn’t all that available for something like the header chain.

About 4 hours to transmit the header chain?

I had the tx rate turned wayyyyy down for maximum receivability. It also did fancy things like broadcast the current headers more often but spew old headers slowly to get you in sync. I don’t remember sync time but I think it was longer.

I'm adding this to the list of things to ask you about next meetup I can attend mate 🤩

Perhaps to transmit transactions in combination with a satellite connection for the blocks?
