RFM95W lorawan stack ?

Post by philwilkinson40 » Sat Dec 09, 2017 9:37 am

Hi All, I have put together a RFM95W shield for WEMOS D1 mini.
https://github.com/TheNitek/WeMos-Lora
The use case is a remote sensor periodically sending a very small amount of information. A low power wide area network protocol like LoRaWAN ticks the right boxes.

I have been able to run the set up using various Arduino sketches written by others. for example
http://things4u.github.io/

After having played with Pycom's LoPy I see the huge benefit of being able to tweak and play with different parameters on the fly with Micropython.
I just wondered if the forum is aware of anyone having attempted a full lorawan stack for the ESP8266 with RFM9# chip?

Apologies everyone, I don't seem to have rights to use BBCode yet so no active hyperlinks or photos...

For the sake of completeness, the RFM95W module employs a Semtech SX1276 chip.
I am also interested in this.

Here are the only two links on this forum concerning the SX127x: Mind you, these are plain LoRa projects; not LoRaWAN!

Here is a LoRaWAN implementation for Python — not MicroPython — on Raspberry Pi.

This may provide some coding inspiration, though.

Here might be what we have been looking for.
Someone made a modified version of Pycom's MicroPython (originally written for the LoPy) adapted for any ESP32 with an SX1272 LoRa module. LoRaWAN reportedly is supported.

thanks for the links @on4aa, I will try and dive into aizukanne's fork of Pycom.

But as a beginner, I really don't have the expertise to take, understand and use a module in this early stage of development.

It seems I may be stuck using Arduino for a while, or perhaps stick with my trusty LoPy instead! :lol:

Pycom relicensed everything to GPL so it is unusable for many. What is interesting though that the original LoRa drives by Semtech seem to be BSD licensed.

You can find the originals from GitHub. Untainted by GPL and still BSD licensed.
