| ## LoRa | ||
| * Branden: The existing LoRa support in Tock is entirely Alistair's effort, but I'll say some things on it. LoRa is long-range wireless (kilometer range) while still at low energy and at low bitrate (kbps). There only exists really one family of chips for LoRa communication, which are usually communicated with over SPI. So Alistair's efforts connect a raw SPI interface to userland, and there are C libraries to drive the LoRa radios over SPI. This would usually have problems with timing, but LoRa is very slow, with a full second between reception and an ACK, for instance. So this works. | ||
| * Alex: A LoRa gateway could be an interesting connection of networks here: LoRa + Ethernet |

I wanted to jump in and say I don't think Tock is a good fit for a LoRa gateway. Gateways tend to be pretty big systems, it really is job for Linux on a RaspberryPi at a minimum.
Tock for P2P LoRa and even LoRaWAN devices I think is a really cool usecase. There are pretty large projects like Meshtastic using LoRa P2P, so it's very handy.
RadioLib (which is the userspace application) supports LoRaWAN. So I'm hoping to support Tock devices as LoRaWAN clients. Then we can have smart Tock sensors transmitting data to TTN!
I already have an example of transmitting sensor data between Tock instances up and running

Thanks for sharing this. I use RadioLib for my classes and it's a really high-quality project. I didn't know they had added LoRaWAN support. And the Tock support you added to it is fantastic!!
