NRF_802154_USE_RAW_API is always being set to 1

[Richard]

We want to use the non raw functions of 802154 such as "nrf_802154_transmit" however they're compiled out by the definition of NRF_802154_USE_RAW_API being set to 1.

How do we ensure this is set to 0?

Using extra CMake arguments didn't work:  Defining preprocessor options using Visual Studio Code 

I've tried variations of the below in the top level CMakeLists.txt file:

add_definitions(-DNRF_802154_USE_RAW_API=0)

add_compile_options(-DNRF_802154_USE_RAW_API=0)

add_compile_definitions(-DNRF_802154_USE_RAW_API=0)

target_compile_options(-DNRF_802154_USE_RAW_API=0)

and also adding CONFIG_IEEE802154_RAW_MODE=n in the overlay file appears to do nothing.

We're trying to get the server and client echo samples to compile having added this:

    nrf_802154_init();

    uint8_t bb[2];
    nrf_802154_transmit(bb, 2, NULL);

Hello,

After you set CONFIG_IEEE802154_USE_RAW_API=0 in your configurations and build. Does the build log give any warnings saying something like "tried setting it to n, but got value y." ?

If you can't find it, then you can also search for the file autoconf,h" inside your build folder. You should probably see at least two of them (one for each core). Do you see CONFIG_IEEE802154_RAW_MODE in any of those files? If so, what are their values?

That being said, I am not familiar with those samples, and whether they actually are set up to use the nrf_802154 API, or zephyr's 802154 stack. Is there any particular reason why you need to use 802154 directly? Do you intend to use it with OpenThread or Zigbee?

Best regards,

Edvin

Hello Edvin,

The build log doesn't have anything like that. There are two autoconf.h files as you say, there are the sub directories if that helps:
build\zephyr\include\generated
build\multiprotocol_rpmsg\zephyr\include\generated

However, CONFIG_IEEE802154_RAW_MODE isn't shown in either file.

For legacy reasons we have to use 'simple' 802.15.4. We were forced to write our own stack to use multiprotocol on the nrf52840 as detailed in this ticket:  nrf52840 Bluetooth and 802.15.4 multiprotocol example project from 4 years ago. But now are you saying there's a complete 802.15.4 stack built into zephyr which we could use?

Hi Richard, 

Edvin is currently out of office. I will forward your answer to our IEEE guys. 

One thing I do note from the west build commands included is that they are missing a double dash "--" in front of -DCONFIG_NRF_802154_RADIO_DRIVER=y

How did you add this line to your build?

Kind regards,
Øyvind

[Richard]

Hi Øyvind,

Thank you, I added the double dash but get the same errors on both projects.

When building via VS code I've added "-- -DCONFIG_NRF_802154_RADIO_DRIVER=y" in to Extra CMake arguments.

The command lines done from the SDK zephyr location with the projects in a different directory.

KR,

Richard

Nearly 2 weeks now, what is the update please? 2 months after raising this ticket and still no resolution.

Hello Richard,

I will ping our IEEE guys on our internal ticket. 

BR,

Hello Edvin,

I'm still awaiting a response. I will be chased yet again in an internal meeting tomorrow, I really don't want another no update response.

Hello Richard,

Sorry again for the late reply. 

Can you please try the attached project in either v2.1.2 or v2.2.0? Use the build command "west build -b nrf5340dk_nrf5340_cpuapp -d build -- -DCONFIG_NRF_802154_SER_HOST=y D802154_rpmsgCONFIG_NRF_802154_RADIO_DRIVER=y"

(The last config, D802154_rpmsgCONFIG_NRF_802154_RADIO_DRIVER=y, can alternatively be added by creating a prj.conf file inside echo_client_rx\child_image\802154_rpmsg\prj.conf, and add the command CONFIG_NRF_802154_RADIO_DRIVER=y in there.)

Best regards,

Edvin
