Need help configuring Kconfig options

[langestefann]

Hi, 

I am trying to merge some features from nRF desktop into my application. More specifically, the BLE CAF features. 

Now I hit a wall. I am getting a lot of Kconfig errors and have no clue how to deal with them:

If I disable some more options (which I do need in the end) I am able to get rid of all but one warning: 

warning: ENTROPY_NRF5_RNG (defined at drivers/entropy/Kconfig.nrf5:14) has direct dependencies !ENTROPY_NRF_FORCE_ALT && HAS_HW_NRF_RNG && ENTROPY_GENERATOR with value n, but is currently being y-selected by the following symbols:

Any tips on what to do? Sifting through all the options is going to take a huge amount of time so I was really hoping there would be a better way... I only really want to add the BLE CAF events functionality to my project.

Kind regards,

Stefan

ps, I run the master branch from ncs-toolchain-master-20210504-3e85a62

[langestefann]

Update: I was able to narrow it down to 

CONFIG_BT_CTLR=y

Should I enable this option? It seems to be the default for many boards?

[langestefann]

Interesting development:

'Rebuild Solution' works fine, but 'Build Solution' now gives this error. Not sure how to fix this? Perhaps I am missing the rpmsg sample in my project?

[Øivind]

Hi,

CONFIG_BT_CTLR should be disabled for the application core, since the network core is used for the bluetooth controller.

You are getting a warning regarding SETTINGS_FCB not being chosen. If you want Settings with FCB you should uncomment all these lines, comment them all out if you don't want it:

#CONFIG_FLASH=y
#CONFIG_FLASH_PAGE_LAYOUT=y
#CONFIG_FLASH_MAP=y
#CONFIG_FCB=y

CONFIG_SETTINGS=y
CONFIG_SETTINGS_FCB=y

Regarding the last error, where have you placed your project, and what does its CMakeLists.txt look like? Are you trying to add hci_rpmsg as a child image?

Also, may I ask why you are using the master branch instead of the latest release (v1.5.1)? You are likely to have fewer issues when using the stable releases.

[langestefann]

Hi, thank your for your response.

I'm not sure. I thought segger would do that for me if I set the right options in prj.conf. But I am very new to this environment so I am still learning. To be honest, I spend a whole day reading documentation and I am still a little confused. I just need the correct config to use BLE on nRF5340

Regarding the use of the master branch, I am using it because I want to use the CAF BLE functionality in my project. It is unfortunately not present in release v1.5.1. I received the zip containing the master branch from a nordic engineer. All I did was install it through the toolchain manager. 

[langestefann]

Just to update you, I have also tried to compile the peripheral_lbs sample and I am getting the same error as with my own app. As a sanity check I also tested the peripheral_lbs sample using the v1.5.1 toolchain again  and it compiles/loads fine. So this is pointing to an issue with the master toolchain, not my app configuration. 

[langestefann]

Another update, I did the following:

- Followed all the steps at https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html#installing-ses

- At first I had the manually installed toolchain installed under C:\users. I got the same error as before. So I moved both project and toolchain to C:\ toplevel. It's now compiling and uploading again.

Updated prj.conf:

My sensor is working again now, except I still have no bluetooth. The log shows the following:

[00:00:00.424,316] <dbg> nrf5340dk_nrf5340_cpuapp.remoteproc_mgr_boot: Network MCU released.
[00:00:00.432,464] <inf> event_manager: e: config_event init_val_1=3

[00:00:00.432,495] <inf> bme680s: Device 0x20000488 name is BME680

My guess is it says 'Network MCU released' because I did not configure something correctly BT related

[langestefann]

Another update: network MCU released message is normal.

I was missing a crucial bit of code in my main application, namely:

#define MODULE main
#include <caf/events/module_state_event.h>

/* Let CAF know main module is ready */
module_set_state(MODULE_STATE_READY);

May I suggest this information is added to the following documentation:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/include/caf/ble_state.html

I can report it's now working great  (although the toolchain is still unreliable!)

[Øivind]

Hi, sorry for the late response

Great to hear that it is working! I will forward your feedback to the people in charge of the documentation.
