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:
