Good morning!

I'm a total newbie to Zephyr, learning the basics to implement in a project for an IoT sensor, more specifically IIoT(Industrial IoT). The module I'm using is a NINAB302, which incorporates a NRF52840. I know that Nordic Semi supports the project and that the microcontroller that I'm using is capable of running it. The IDE I'm using is Eclipse with the Zephyr pĺugin for it.

My question is about the Devicetree aliases defines in the C/C++ code for example those in the Blinky example: "DT_ALIAS_LED0_GPIOS_PIN" .
In my that code, eclipse isn't able to find the source of the aliases and freaks out putting red errors all over the place. But when I build the project, none of the errors matter, it builds perfectly and I can even flash the code to the device flawlessly. That's nice and all, but I feel like those defines could be very helpful if I knew where they were and how to use them.

So, how the devicetree aliases defines works? Where are they found? And how can one create their personal defines?

Hi,

Thanks for the quick reply.

I tried connecting and disconnecting several times. Also tried reinstalling the app. After waiting for some minutes, it still displays Zephyr. Is it possible that the local name differs from the advertising name?

Regards,

Jamie

Hello,

I want to change the ble device name during runtime. I've enabled BT_DEVICE_NAME_DYNAMIC and BT_SETTINGS.

To change the device name during runtime i'm using bt_set_name(). However, when scanning for the device using the nrf connect toolbox app on my android device, i still see ''Zephyr'' as the device name. Only after connecting with the device, i see the correct new device name that was set by bt_set_name().

The bt_set_name() works, but not the way i would like to. Is there a way to show the changed device name before connecting with the device?

Kind regards,

Jamie

Hi,

I moved

set ( $ENV{ZEPHYR_EXTRA_MODULES} pbs_path/module1)

before

include ( $ENV{ZEPHYR_BASE} /cmake/app/boilerplate.cmake NO_POLICY_SCOPE)
project (NONE)


Unfortunately I am still getting the same linker error.

Best regards
Stefan

Hi,

I want to add a module to my project. My folder structure looks like this:

| | |---zephyr

*Where modules/module1/CMakeLists.txt:*

zephyr_interface_library_named(test)
target_include_directories(test INTERFACE inc)
zephyr_library()
zephyr_library_sources(
src/test.c

zephyr_library_link_libraries(test)
target_link_libraries(test INTERFACE zephyr_interface)

*modules/module1/zephyr/module.yml:*

build:
cmake: .

*app/app1/CMakeLists.txt:*
cmake_minimum_required (VERSION 3.13.1)
include ( $ENV{ZEPHYR_BASE} /cmake/app/boilerplate.cmake NO_POLICY_SCOPE)
project (NONE)

set ( $ENV{ZEPHYR_EXTRA_MODULES} pbs_path/module1)

Looking at this quickly, ZEPHYR_EXTRA_MODULES needs to be set before
including the boilerplate file, not before. You can also set it as an
ordinary CMake variable; you don't need to set it in the environment.

FILE (GLOB app_sources src/*.c)
target_sources (app PRIVATE ${app_sources} )
target_include_directories (app PRIVATE $ENV{ZEPHYR_BASE} /subsys/net/ip)

target_link_libraries (app PRIVATE test)

Unfortunately, with this set up module1 doesn't get compiled and I get a linker error when I try to use functions from that module. I assume that something goes wrong with ZEPHYR_EXTRA_MODULES but I don't know what.

HTH,
Marti
