stm32wba65 and I-CUBE-LRWAN

[SLevi.1]

I have a custom board with stm32wba65 processor. I also have an RFM95 LoRa module. I need to add LoRaWAN capability. I tried adding I-CUBE-LRWAN into my CubeMX but was not able to load it (not a recognised package).

How can I get an ST or Semtech approved LoRaWAN stack into my project?

Please do not suggest I use stm32WL processor.

Indeed, I-CUBE-LRWAN is not a "Package" in the CubeMX sense.

It's just a load of source code, which you add to your project manually. Or start from one of the supplied examples in it.

PS:

See also: I-CUBE-LRWAN Projects do not have .ioc files.

@Imen.D - is there any progress on making that CubeMX version?

EDIT: link corrected.

Ok, so I took the example for stm32L476, and copied the LoRaWAN folder across.

How do I specify that we are using:

1. RFM95 (sx1276) board
2. stm32WBA65 processor
3. spi3 for comms
4. PC13 for CS

Is there a header file to set this up? or do I just edit the .c files directly?

[Andrew Neil]

The processor you specify in the IDE Project;

The other stuff, as mentioned in the linked thread, is all done in the HAL code.

Yes, there should be (a) header(s); eg, mlm32l0xx_hw_conf.h has:

I assume there is a step-by-step guide to integrating I-CUBE-LRWAN into an existing stmcubeide project? This must have been done before, right?

b.t.w. your link does not work.

Not as far as I know.

I worked the other way: started from an I-CUBE-LRWAN project, and integrated my stuff into that

Oops, sorry - now fixed.

[Andrew Neil]

Hmm, there should be documentation on the Product Page - but it seems to be broken at the moment:

https://www.st.com/en/embedded-software/i-cube-lrwan.html#documentation

Is there a PDF included in the download?

I can see the documentation content:

Not here - Win-11 Chrome :

Also on Edge

[mƎALLEm]

Same config but I don't have the issue! maybe you need to close Chrome and restart?
