GNU Radio LoRa PHY level receiver & transmitter
(sh.itjust.works)
Research results on reverse engineering of the LoRa protocol and an implementation in GNU Radio. An open source LoRa PHY layer project provides access to the LoRa protocol for researchers and hobbyists.
Maybe you ought to look more into what GNU Radio/SDR is capable of before defending this hill you're standing on.
It's certainly not capable of flashing in one step to a chip already on board. That's the hill you're trying to climb.
GNU projects often are sucky. Implementations of things that already exist as they happen upon them and after their uptake. Then people like you come in and defend them. 95% of the time they fail because the existing solution works fine.
I couldn't spare an extra thought about using the GNU brand over another FOSS solution. Anyone in here stomping their feet about this is an absolute moron.
I am quite familiar with Lora hardware, I'm currently running 8 mesh devices. I've done the remote flashing, I've also had remote flashing disable devices and needed to reflash over USB.
This is a completely different use case.
Also, GNU ...brand?
