FINALLY!
I was able to defeat Ant+.
Yes, thank you very much, the problem was in sysbuild. I saw in Nordic's YouTube video that they check the "sysbuild" box.
I racked my brain for many days and couldn’t figure out what the problem was. It's good that you were found!

Then I'll ask more questions. Please tell me where I can get acquainted with all Ant+ profiles (I'm interested in cycling ones). And in general, where is the documentation on working with Ant+ for beginners like me?

As of sdk-nrf v2.6, ANT samples do not support sysbuild - the Kconfig auto header shows SB_* defines so I think that is the problem. The child image feature for the samples relies on partition manager to build ANT onto the network core.

I believe the sysbuild checkbox should be unchecked by default in VS Code, but please confirm.

I apparently chose this by accident. Of course I'm working with nRF5340, and building a project for my board (nRF5340-DK).

I rebuilt the project, but the error did not go away.

Wherein I ran “git status” and everything seemed to be fine (as far as I understand).

Also I don't have the "ant_rpc" folder in the "build" folder:

Here are two autoconf.h files that I found in the project folder:

The "CONFIG_ANT_LICENSE_KEY" field is not in any of them.

I don't know if this will help you, but I put together a project for nRF53 (for my board) and am sending it to you. Maybe you can use some logs to determine the cause of the error.
devzone.nordicsemi.com/.../8206.sample.zip

Thank you for your help, I hope that we can solve this problem.
Sincerely, Victor!

Hi Victor,

Thanks for running these steps! I think we're getting there.

The build log shown is for an nRF52840. If you are building for nRF52840, the license key needs to be set in prj.conf. Since it is a single core chip this is the only configuration file that applies (there is no child_image in this case and ant_rpc.conf is unused).

If you are intending to build for your nRF5340, child_image/ant_rpc.conf is the correct file for the license switch. Use "Add Build Configuration" to set up a new build for board nrf5340dk_nrf5340_cpuapp. This will use the child_image feature to automatically build for the network core based on the configurations in the ant_rpc.conf file.

Let me know if this works!

Good afternoon.
I really hope that you can help me!

1. I checked “git status” in the folder you specified, the following error occurred:

C:\ncs\v2.6.0\ant>git status
HEAD detached at 39a2222
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: init/Kconfig

no changes added to commit (use "git add" and/or "git commit -a")

I fixed everything (now there are no changes), but now I can’t build the project... During building I got this error:

And this despite the fact that I have “CONFIG_ANT_EVALUATION_KEY=y” specified in the “child_image\ant_rpc.conf” file. Quite strange.
Or is this how it should be?

That is, there is still some nonsense with the Ant+ key.

2. No, I have an empty line there, no key.

#define CONFIG_ANT_LICENSE_KEY ""

I really like your tips, I see that they bring me closer to a solution! Please help me solve the problem! I previously worked on Arduino, so I have no experience with NCS.

I will look forward to your help.

Sincerely, Victor.

Hello, I am from the ANT team. I'd like to check two things first to help diagnose your issue.

1. In the ANT folder, ie. C:\ncs\v2.6.0\ant, please run a "git status" and make sure that there are no local changes to the repository that might be affecting what is passed to the ant_init() function.

2. Ensure the license key is propagating correctly through Kconfig. One way to double check this is to check the autoconf.h file that is generated as part of the build. For nRF5340 network core, this file is located at this relative path:

hrm_tx\build\ant_rpc\zephyr\include\generated\autoconf.h

Can you confirm the following is being set as expected?

#define CONFIG_ANT_LICENSE_KEY "license-string"

The string that follows CONFIG_ANT_LICENSE_KEY is passed directly to the initialization function and should exactly match the evaluation key defined here: https://github.com/ant-nrfconnect/sdk-ant/blob/main/init/Kconfig#L13

In this particular case I recommend to ask for support on https://www.thisisant.com/ , they are the ones that both develop the ANT stack and licensing, and should be best able to look into your problems with -NRF_EINVAL (ANT License Key argument is invalid).

Maybe you can see a difference between our views when buildling:

I built your project, tried to run it on my board - I get the same error "<err> ant_init: ant_stack_init() failed: -22", "<err> ant_rpc_net: cmd handler missing cb"

I also tried running it in debug mode.

The program stops at this point.

I have a big request to ask you - if you don’t know how to help me with this problem, please refer me to another employee of yours.
I really don't want to ask new questions, but I have to, since I bought a NEW board and can't run the example code, I don't think it should be this way.

I will look forward to your help.
Sincerely, Victor.

Good afternoon.

For some reason I did not receive a notification, so I did not notice your message.
DropMeFiles is a very popular file sharing service (it’s been around for over 10 years). Honestly, I don't know why you consider it's dangerous.
I didn't know about the ability to upload files directly to the forum.
devzone.nordicsemi.com/.../hrm_5F00_tx.zip
Now I’ll check your file to see if it works for me.
And you, please, check my file.

Thank you very much for your quick response.
Sincerely, Victor

Good afternoon.
Thank you for your quick response.

The whole point here is that at the moment (see my steps above) I am NOT using my Ant+ key (I use CONFIG_ANT_EVALUATION_KEY=y). So I don't really understand how it can be invalid.

[quote userid="2111" url="~/f/nordic-q-a/110228/problems-with-running-the-hrm-example-ant/479286"]Edit: You can try to zip your project with the change to "child_image/ant_rpc.conf" and I can try to run it here.[/quote]

I would be grateful to you. Let's check.
I zipped the project file and uploaded it on DropMeFiles:
https://dropmefiles.com/dMHKK

By the way, maybe let's do the opposite? You managed to launch the project. Maybe you can zip it and send it to me, and I'll try to load it onto my nRF53 board

Thank you!
Sincerely, Victor.

You can try to delete the build folder and re-compile to check if that helps. The last error you shared is due to -NRF_EINVAL if the ANT License Key argument is invalid, from the ant_interface.h:

/******************************* RE/INITIALIZATION API *******************/

 /** @brief This function checks for a valid license key and initializes the ANT stack (including stack variables). It must be executed prior to any wireless protocol activity.
 *          By default, it will be called during kernel initialization by ANT for nRF Connect SDK initialization code.
 *
 * @warning This is an internal glue function intended for SYS_INIT, it is not necessary to call it directly. This function is only meaningful on processor cores used for radio communication and may have a dummy implementation on multicore SoC's.
 *
 * @param[in] aucLicenseKey is a pointer to an ANT License Key. This key is managed via the :kconfig:option:`CONFIG_ANT_LICENSE_KEY`.
 *
 * @retval  0 Success
 * @retval  -NRF_EPERM if the stack is not enabled
 * @retval  -NRF_EINVAL if the ANT License Key argument is invalid
 */
ant_err_t ant_stack_init (const uint8_t *aucLicenseKey);

So not something I can help you with directly, you would need to reach out to thisisant.com if there is problem with your license key.

Edit: You can try to zip your project with the change to "child_image/ant_rpc.conf" and I can try to run it here.

[quote userid="2111" url="~/f/nordic-q-a/110228/problems-with-running-the-hrm-example-ant/479140"]I have tried to recreate what you are doing, but it seems to work here:[/quote]

It's good that it works for you, but it doesn't solve my problem.
I recently bought a NEW nRF5340-DK, I'm trying to run the usual example, showing my steps step by step - and it doesn't work. I turn to you for help, and you say: “Everything works for me.” Tell me, as a Nordic employee, what should I do in this situation? How should I react to the fact that it works for you, but not for me? My task is to run on my board.
I DEFINITELY need to use Ant+ technology and that's why I bought the nRF 53 series board because they are the only ones that support Ant+ in your new development environment (NCS).

I am asking for help in the hope that you will help me resolve my issue. If I do something wrong, correct me, tell me how to do it. If it doesn’t work for me specifically, tell me, maybe I should reinstall something.

With all due respect to you and the time you spend on my questions, your answer did not bring me any closer to solving the problem. I really hope for a constructive response aimed at helping me with my question. At the end of the day, my goal is not to get into an argument with anyone or prove that the board doesn't work, but my goal is to RUN the Ant+ EXAMPLE CODE.

Let us together try to solve this problem.
For example, what does this error mean:
<err> ant_init: ant_stack_init() failed: -22
<err> ant_rpc_net: cmd handler missing cb
I didn't find the answer. I am sure that you, as an employee, have a better understanding of your own product. If you personally don’t know the answer to my question, let’s ask an employee who can figure it out. After all, the one who programmed and wrote the Ant+ library for NCS.

As for the fact that I have “a very old nRF5340-PDK” - you are mistaken. I have a new nRF5340-DK (not PDK). Here's a photo:

I sincerely ask you to help me with this question!
I will look forward to your answer,

[quote userid="2111" url="~/f/nordic-q-a/110228/problems-with-running-the-hrm-example-ant/478945"]В качестве первого шага вы можете попытаться закомментировать параметр CONFIG_ANT_LICENSE_KEY и просто использовать CONFIG_ANT_EVALUATION_KEY=y в качестве проверки вашей среды сборки и аппаратного обеспечения. Есть ли разница, если вы измените существующий пример как есть (без создания нового приложения)?[/quote]

That's exactly what I do.
Take a close look at the second screenshot I attached to my post above.
This is the file "child_image/ant_rpc.conf", I deleted the line with my ANT key (CONFIG_ANT_LICENSE_KEY), and also specified the parameter CONFIG_ANT_EVALUATION_KEY=y
What am I doing wrong?

Let's go through the stages of creating a new project with you.
1) I create a new project, select "Copy a sample", I open it in a new VS window

2) I go to the file "child_image/ant_rpc.conf", there I change to "CONFIG_ANT_EVALUATION_KEY=y"

3) Then I create a new build. Just select nRF5340DK and click "build".

4) The last step is I connect my board and click "Flash"

It writes to me, saying that the device is programmed. Should work, right?

Interestingly, this time I didn't get any errors. This is great!
After waiting a couple of minutes, I still couldn't find my board using the Garmin Edge device.

I'll translate: it says "To connect to the heart rate monitor, wear it".
At this time, an error related to Ant+ is written on VCOM0:

So what kind of error is this? Maybe my sequence of actions is incorrect? Maybe I'm missing something?
<err> ant_init: ant_stack_init() failed: -22
<err> ant_rpc_net: cmd handler missing cb

Hello,

Please check out the following information:
https://www.thisisant.com/APIassets/ANTnRFConnectDoc/doc/integration_notes.html#license-keys

For the nRF5340 the following applies:

"If using the dual core automatic child image, the radio-adjacent or network core image (cpunet) configuration file will be either child_image/ant_rpc.conf or child_image/hci_ipc.conf."

As a first step you can try to comment out the CONFIG_ANT_LICENSE_KEY setting and just using CONFIG_ANT_EVALUATION_KEY=y as a check for your build environment and HW. Any difference if you modify the existing example as-is (without create a new application)?
