How can I read the logs from an external nrf52840 using VS Code and nRF5340-DK

Hello,

I have Micromod nRF52840 module on a carrier board and I've built and flashed Matter Light Switch sample on it but I need to read the logs from the module

How can I read the logs from this external nrf52840 module?

Best regards,

Basem

Hi,

You could connect the log module to a UART or RTT and connect the 5340 to the 52840 with said UART and read out the logs this way. You might find some useful information in https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-2-debugging/

Kind regards,
Andreas

Thanks AHaug, and i'm sorry for my late response.

The following URLs helped me:

devzone.nordicsemi.com/.../log_-over-rtt-and-shell-over-uart2
https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/test_and_optimize/logging.html

Conclusion:
I used the following configs to enable RTT to send the logs from the custom nRF52840 board through nRF5340-DK to VS Code:

#CONFIG_UART_CONSOLE=n
#CONFIG_RTT_CONSOLE=y
#CONFIG_USE_SEGGER_RTT=y

Best regards,
