LR1110 on nRF52840 board

Thanks for the clarifications.

Yes, I agree with your first first impression: While there are lr1110 source code to be found in the SDK, this is not linked up against any Zephyr driver, and you can therefore not use it like you try to.

Instead, you would have to add the driver in a Zephyr way. See DevAcademy on Lesson 7 – Device driver development.

Sorry didn't make myself clear
This is what I'm referring to

Here are the errors I get in the bulid
I do have CONFIG_LORA=y

CONFIG_SPI=y

CONFIG_SPI_NRFX=y

CONFIG_SPI=y

in the prj.conf

No SOURCES given to Zephyr library: loramac-node

When you say "cannot be selected", can you share the build logs with the error saying this?

Sigurd

I have the same set of files - see below screenshot

The problem is that I cannot select "semtech,lr1110" in the "compatible" section when I define the lora0 dts node
The following semtech devices can be selected: sx1272,sx1261,sx1276 but there is no lr1110
How do I get around that?

Rajeev,

The SWDR006 driver also does not exist in the SDK, so could you please clarify your instructions

Thank you

Hi Andy,

[quote user=""]there is no driver code there[/quote]

I can see driver code for my SDK install:

Maybe something went wrong in the installation?

Try to run "west update" again, and check the folder again.

Regards,
Sigurd Hellesvik

I hope this helps: https://github.com/Lora-net/SWDR006. I don't see a direct support here and also in Cmake
