LoRaWAN anybody experimenting with this? - Larz60+ - Sep-13-2021
I have been following the advancements of LoRaWAN over the past few years, because the concept of a tiny little transceiver operating WAN without internet has fascinated me. There is now a development kit available for a measly 25 bucks from seeed studio (The LoRa-E5 https://www.seeedstudio.com/LoRa-E5-Dev-Kit-p-4868.html ). I purchased a couple of these about a week ago, and waiting for their arrival. As far as I can tell, most everything needed to get up and running is here. And now, $5 per month satellite access is available from swarm.
Here's an older (7 months ago) article on the swarm effort: https://www.semtech.com/company/press/semtech-and-swarm-deliver-satellite-communications-with-lora
As of today there are now over 100 satellites in Geo-stationary orbit, with 100 % coverage of Earth. Each satellite is about the size of a sandwich.
This, blows my mind and excites me to no end.
Most of the code I have seen is written in C. But with the computing power of this latest development board, I will attempt to get some python code up and running soon.
Some of the dev board features:
- Full GPIOs led out from the Lora-E5 STM32WLE5JC
- Global LoRaWAN® and LoRa frequency plan supported
- Long-distance transmission range to 10km (ideal value in open area)
- Mini and compact size, suitable for rapid testing and building small size prototype
- Convenient RESET and BOOT buttons on board
- world-first combo of LoRa RF and MCU chip into one single tiny chip and is FCC and CE certified, powered by ARM Cortex-M4 core and Semtech SX126X LoRa chip
Again, I'd love to see and hear from others who are currently experimenting, or are interested in the subject.

That does sound interesting. What are you going to try to use it for?

Right now, I'm in the process of learning how to configure the thing.
Next I will hook up to the satellite, and just snoop around to see what's out there.
Finally, I'm hoping that I can come up with a not so hair-brained idea for something useful,
probably fool around with the TeseoVIC3DA Dead reckoning GNSS modules and hook that up to OSM for mapping.

Open to any type of experimentation.

Here's an interesting video:
First LoRa Satellite launch video, (Julian Fernandez (16 years old)) it's old for this technology, nearly 2 years ago, but of interest to see how it all started (There are now 113 satellites (perhaps more)). https://www.youtube.com/watch?v=5k0aM-PJzo8
