RE: Integration Error When Adding BLE Functionality to nRF52840 Custom Board Application

Hello,

It looks like your device tree selects the legacy UART instance and not the UARTE with DMA support, which is needed for using the asynchronous UART driver. To confirm this, please try building your project for the 'nrf52840dk_nrf52840' board and check if the same error occurs. If it doesn't, you can then compare the 'zephyr.dts' file generated in the 'build/zephyr' directory with the one generated when building for your board.

Hello Vidar,

I have previously utilized these CONFIG options, but the issue persists with the same errors. Additionally, I forgot to mention earlier that I am encountering yellow underlined Kconfig options in my prj.conf, accompanied by the following warning:

CONFIG_UART_ASYNC_API was assigned the value y, but got the value n. Missing dependencies: SERIAL_SUPPORT_ASYNC

CONFIG_UART_CONSOLE was assigned the value y, but got the value n. Missing dependencies: SERIAL_HAS_DRIVER

Also getting CMakeList and KConfig warnings as follows:

When I look into the .config file, there is no option which contain the CONFIG_UART_1_ASYNC with y.

So is the warning wrong and the async option is activated anyways?
How can I make sure the async option is used?

Best regards!

Hello,

Sorry, I overlooked the other errors. Those indicate that you are missing relevant kconfig settings to enable the async UART driver. Please ensure you have the following symbols enabled in your project:

CONFIG_UART_ASYNC_API=y
CONFIG_NRFX_UARTE0=y
CONFIG_SERIAL=y

Hello Vidar,

Thank you for your prompt response. Unfortunately, I have previously attempted the suggested solution, but the issue persists. The error message I'm encountering is as follows:

I suspect there may be an issue with the CMakeFiles. Additionally, I would greatly appreciate it if you could suggest the best approach to seamlessly integrate the 'peripheral_uart' code with the main application code. Or any other link that may be helpful.

Thank you for your assistance.

Hello,

You need to define the 'nordic_nus_uart' property in your devicetree to inform the application which USB/UART interface you intend to use for serial port emulation. The peripheral_uart sample uses UART0 by default:

/ {
	chosen {
		nordic,nus-uart = &uart0;
	};
};

Best regards,

Vidar
