Hi there,
I just wanted to ask if anyone maybe used LoRa(Wan) RF modules with Nerves already?
I have a couple of usecases where it would be nice, but don’t have a clue how this would work.
I assume via GPIOs/serial communication?
Did anyone connect other RF modules or sensors like that?
Thanks,
Christoph

Not yet. I’m waiting for some Kickstarter funded LoRa modules to arrive (hopefully in the next few weeks) and I will be playing with them using Python to start with but would love to eventually develop a Nerves system with them. However for things like this I think I’m going to be in the hands of more experienced hardware-aware developers to create libraries for me.

Hi all,
I started a module for LoRa radios that use SPI. If anyone is interested in helping or giving suggestions, this project is on Github, in the link below:

Same here - we are already using LoRa modules with arduinos and RPis, but I’m not an expert on low level programming.
It would be a nice combination, although probably not high in priority for the nerves community (e.g. OTA updates are not easily doable, low power is not a priority when using RPis, etc).
We have the use case that we need to integrate various devices over ethernet, process a lot of data, and send aggregations over a non-internet (LoRa) connection back.

@brunosantanaa finally got all the needed HW.. so will give it a go soon..
ended up going for the same module as you have, as to not complicate things
eg:
2x RFM95(w) for europe 868Mhz (~9 usd on ebay)
this breakout board/hat
https://www.tindie.com/products/qqqlab/rfm69-radio-hat-for-raspberry-pi/
fyi my board/hat came with ufl solder pads for connecting external antennas, which is very nice..
I also have a gateway The Things Indoor Gateway | The Things Network since there wasn’t good/consistent coverage at my place - you can check https://ttnmapper.org for gateways close by..
soon-ish I’ll get the radios ping-ponging on simple lora..
then attempt to get lorawan/ttn working building upon your wan branch GitHub - brunosantanaa/Elixir-LoRa at wan · GitHub - first a simple “abp” connect/send, then work from there (receive/otaa etc)..
I may start out using https://github.com/ivajloip/rust-lorawan/tree/master/encoding via rustler for encoding/decoding packages if needed.. just to get something working asap..
