USI LoRa module

Anyone else ported I-CUBE-LRWAN to the USI Module?

What's your experience with the RSSI level vs other SX1272/SX1276 solutions?

I planned to spend one hour to get it work and play with the gateway and server, but after half of a day i got headache, should have bought B-L072Z-LRWAN1.

I-CUBE-LRWAN demo examples does not work without modifications, but cant do a thing when there is no proper documentation for I-NUCLEO-LRWAN1.

There is link to

https://github.com/USILoRaModule/USI_I-NUCLEO-LRWAN1

with some instructions that don't work for me, tried

End_Node project but got exception inside 'SX1272Init( RadioEvents_t *events )', will check it tomorrow, maybe i will have more luck.

I used serial connectivity via LPUART1

Indeed.

I created a pin table, and do actually have the CUBE LRWAN software building for it. You have to wire up the SWD header, and also nuke the firmware because USI has ROP enabled.

The board can then at least be free-standing, but the SX1272 and smaller L0 makes it somewhat less appealing than the Murata. Still enough space to make a Mote using the on-board sensors.

Any chance of a copy of that, please ... ?

Will try pasting it here, hopefully will look a bit better,

The module product page is here: 

http://www.usish.com/english/products_WM_SG_SM_42.php

 

Datasheet: 

http://www.usish.com/pdf/WM-SG-SM-42_Product%20SPEC.pdf

 

There is a link to the ST page for the I-NUCLEO-LRWAN board: 

http://www.st.com/en/evaluation-tools/i-nucleo-lrwan1.html

  - but no information at all.

The onboard sensors would be interesting, but I cannot find any documentation ANYWHERE that outlines what sensor is connected how to the USB module (well, the ST source does show how things are connected to the Arduino headers).

Also no description of the SBs and jumpers ...
