nRF52832 Direct Test Mode

I got it figured out. I just had to search the "Copy a Sample" directory under "Create a New Application". I was able to find radio_test under lpuart. Once I made a build configuration and flashed the board everything worked like a charm. The UART radio test commands must be sent in the nRF Serial Terminal. You can close this ticket. Thanks.

Hey Jonathan,

Thanks for the timely response.

I checked out the links you sent. They appear to be pretty straight forward. But there remains an issue. I cannot open the folder nRF5_SDK_vxx\examples\peripheral\radio_test\board number\blank in VS Code. The radio_test/pca10040/blank folder only contains configuration files for an SES project (radio_test_pca10040.emProject). I am trying to use Visual Studio Code because SES IDE is deprecated by my understanding. In order to use this radio_test example, do I need to go back to SES IDE, or is there a way to bring the project up in VS Code? According to this:

https://devzone.nordicsemi.com/f/nordic-q-a/92198/unable-to-add-ses-project-to-vsc-nrf-connect#:~:text=The%20SES%20project%20uses%20the,and%20built%20in%20VS%20Code.

migrating from an nRF5 SDK SES project to nRF Connect project in VS Code is not trivial as the APIs and libraries are different.

So my question is: Should I try to use the deprecated SES IDE to bring up this example, or is there a way to do it in VS Code that I am not aware of?

Thanks,

-Jake

Hi,

You can use direct test mode (DTM) as well for the nRF52832, but since you only require a continuous waveform mode you can use the Radio test sample. It has a unmodulated Carriere option and you just select output power and channel.

Radio test info:

There are some other blogs on this,

Imagery might be a bit outdated on these blogs post but concept is the same.
