How to best integrate DTM sample in NRF53 application?

[sillvi]

Hi,

I am quite new to nrf's and zephyr and I'm working on a product that requires Direct Test Mode functionality. I started with the DTM sample and am now looking at how it can be integrated into our application running on an nrf5340 but have found very little information on this. I have not been able to figure it out myself either because I don't have the experience to tackle the fact that the sample needs to be build for the net core but our application is built on the app core.

What is the best way to integrate this sample into my application? 

The original idea was to be able to send a shell command which puts the device in direct test mode and then you can start sending commands to run the tests, but other options e.g. using a button are not off the table if they're simpler.

Thanks,

Silvia

Hi

As of today, the Direct Test Mode(DTM) code does not support Dynamic interrupts. This is needed for having it integrated as part of the application. So today, the only supported solution is to have the DTM as a separate hex file that you program to the chip when you want to do DTM testing.
