BLE DTM with Zephyr project SDK 2.7.0

[Georg Jahnen]

I like to use the DTM mode in a test mode of our device based on nRF5340. Using SDK 2.7.0 with Zephyr. Started with using the DTM example but it does not build. Beyond other errors

NRF_RADIO_Type

is not defined.

How can I use DTM on nRF5340 with Zephyr / SDK 2.7.0

Hi Vidar,

the zip I have attached. It is just the nrf sample for DTM.

Please have a look at it

Best regards

Hi Georg,

Thanks, I just wanted to make sure nothing was changed in the project configuration. It seemed like the linker errors did not match the source code. Unfortunately, I have not managed to reproduce the build issue here. 

Does your the cmake output in your build log show that this overlay is found as in my case below?

This overlay selects the communication interface to use with DTM:

It would also be helpful if you could share your build log.

Best regards,

Vidar

Hi Vidar,

think I found the reason. May be I mixed up the sample from 2.9.0 and tried to build it with 2.7.0 after build with 2.9.0 failed.

I deleted everything and setup the DTM sample again by taking care of diffenrent versions of SDK

Now I could build it, but: With the nrf Connect DTM program I can not access it. DTM tries to communicate with COM Port, but there is no response. Tried both COM ports provided by DK.

How can I use this example with the nrf connect DTM tool?

Best regards
Georg

I could just get the serial communication running. But I do not know what I have done to get it running.

I gave up with DTM
