Dear people who want to #decentralize everythingband are a fan of #LoRa, #meshtastic and #OpenSource,
I'm writing to you today to inquire where you stand on the fact that it's all based on a propritary radio, created by a single company. If they were to discontinue this line, it'd mean no new hardware.
It may sound unlikely to discontinue a product that people love, but this recently happened with GoTenna. You can still use existing hardware, but no new gear, no support, no growing your network, no bringing other people in.
Has anyone successfully used an SDR to interface with LoRa? That would eliminate the single point of failure.
This also applies to things like #reticulum and #NomadNet which also rely on LoRa.
Do you know any good reference material for packet radio?
I read the standard a while ago, but it didn't click with me.
I went through the free LoRa/LoRaWAN training from Semtech a couple years ago and it was very good at explaining how it works to non-experts.

IIRC, you might have to look up videos on thinks like OOK or preambles to understand those parts, but that's easy once you know what to look for and have the context of how it is used.
I mean the ax-25 packet radio protocol still used by some ham radio enthusiasts.
It went out of fashion, but its certainly not tied to a manufacturer. Something to consider.
That said , all the lora chips I use are chinese clones

Hackathon idea.
definitely would be a top contender for first place
If people are serious about this, I can chip in with regards to the hardware.
I just bought enough hardware today to build 60 devices, feel free to bring your own hardware stuff too! The more the merrier.
I thought that a few years ago some radio researchers had reverse engineered LoRa, or maybe had constructed grc-LoRa? A quick search showed this:

Not sure if that was sort of what you were after?
