Even if you will eventually develop the application on a Dongle, a Dev Kit is still a better place to start to gain familiarity with the product, the tools, etc ...

If you insist on doing logging through the USB interface on the nRF52840 Dongle, please check out my colleague Jimmy's blog post on how to use the nRF52840 Dongle as a development board. I would still agree with awneil though. The Development Kits are much better suited for actually developing an application.

Best regards,

Thanks for your answer. Is there a relationship beetween LOG and CLI interface?

When I enable the LOG, LED 1 on the dongle stop work properly. And when is defined the CLI interface, LED 1 stop work properly? Do you know why?

Best regards

It really doesn't matter what terminal you use - any one will do.

But, of course, if the logs are not going to that COM port - then no terminal is going to see them!

If the logs are going to RTT, you will need a Segger J-Link debug adaptor and either their standalone RTT viewer, or the viewer in the Segger Embedded Studio (SES) IDE.

For development, it is always recommended to use a Development Kit (DK; the clue is in the name) rather than a Dongle:

https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52840-DK

two key features that gives you that aren't on the dongle:

You get access to the hardware UART
You get a built-in Segger J-Link debug adaptor

you also get a much wider range of examples to choose from.

Thanks for your answer. Can you explain me your method to view LOG? Thanks

Do you use putty?

I'm not sure if the UART Backend works over the CDC ACM ?

I've only ever used on the hardware UART.

Thanks for your answer. I enable NRF_LOG and NRF_LOG_BACKEND_UART from CMSIS configurator but I still don't see any log on putty.

It's a setting in the sdk_config.h file

devzone.nordicsemi.com/.../275167

The Nordic SDK is a bit of a leap for someone new to programming! 😮

I would suggest Nordic's own getting started materials:

Sorry, I'm new at programming so I'm a bit confused. How can I configure the project to send logs to the UART? I follow this video: www.youtube.com/watch

Is the project configured to send logs to the UART? Some default to RTT ...
