I Nucleo lrwan problem

[Hamdi Oussema]

I'm currently using I Nucleo lrwan1 shield and STM32L073 to create a Lora end node. I downloaded the latest I cube lrwan (v2.0.0) and there is no configuration to the I Nucleo lrwan1. So I can't make it work.

So, is there anyone who has the same problem or can anyone guide me to make it work.

I also posted the problem on the TTN forum and they recommended me to ask the st community about this problem

@Community member​ : "Not sure ST provides firmware for the USI model"

They don't provide firmware for the USI module itself, but they do provide the AT_Master project to communicate with the USI module when it's mounted on a Nucleo board.

Unfortunately, they appear to have broken it in I-CUBE-LRWAN v2.0.0 (March 2021) :

@Imen DAHMEN​ - any chance of getting anyone at ST to look into this?

PS

@Imen DAHMEN​ - or, at least, provide a download link for v1.3.1 in the meantime ...

Hello,

I will try to contact expert internally to review this post.

The older versions used to present, I do have this stuff archived

There were some other reports of the support of the USI being an issue, and generally that LRWAN2 and LRWAN3 could do with some actual ownership/responsibility rather than being delivered pre-abandoned..

On another front I did port V1.1.1 to an STM32F103 platform, ~900 MHz LoRaP2P with supposedly a 2W PA driven via an 8-bit I2C DAC, toasty..

Thanks for the Zip.

"There were some other reports of the support of the USI being an issue"

Indeed - my name would be on some of them. It took ages to get them just to publish the schematics of the I-NUCLEO-LRWAN1 board.

:\

"and generally that LRWAN2 and LRWAN3 could do with some actual ownership/responsibility rather than being delivered pre-abandoned.."

Likewise.

ST tout these as "Partner" companies & products - there really needs to be some better commitment from both ST and these "Partners" to provide and maintain a decent level of documentation.

Perhaps @Imen DAHMEN​  could also find someone to look into that ... ?

thanks - ST expert has responded in this thread:

https://community.st.com/s/question/0D53W00000vP1XtSAK/icubelrwan-v200-with-nucleol073rz-board-and-inucleolrwan1-shield

It is confirmed that the AT_Master project in I-CUBE-LRWAN v2.0.0 (March 2021) does not work out-of-the-box.

You are welcome.

Thank you for your contribution and thank you for your patience while we work on this.

@Community member​ "there is no configuration to the I Nucleo lrwan1"

Not quite sure what you mean by that?

[Hamdi Oussema]

@Andrew Neil​ as you can see here : https://github.com/USIWP1Module/USI_I-NUCLEO-LRWAN1 there are some configurations to be done depending on the I cube lrwan version.

[Andrew Neil]

Hmm ... I thought I'd replied to that yesterday?

That page refers to a very old version of I-CUBE-LRWAN - I just followed the instructions in the P-NUCLEO-LRWAN2 User Manual.

But it has been noted that these need updating for v2.0.0 of the I-CUBE-LRWAN:
