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

[Vidar Berg]

Hello,

If you get an error saying NRF_RADIO_Type is not defined, it usually means you have attempted to build the project for the application core instead of the network core. The application does not have direct access to the RADIO peripheral.

Supported build target:

https://docs.nordicsemi.com/bundle/ncs-2.9.0/page/nrf/samples/bluetooth/direct_test_mode/README.html 

Best regards,

Hi Vidar,

thank you for your quick answer. This sounds resonable.

Took the network core with SDK 2.7.0 and get a compile error due to missing header files

So far could not find any combination of SDK or config file to get the project build

I see you've switched to SDK v2.9.0. Does your Build configuration match this:

?

[Georg Jahnen]

Hi Vidar,

Yes, my build configuration matches this.

Switching to 2.9.0 was just due to lack of other ideas. Our project bases on 2.7.0 and we like to stay with that.

But building neither works for 2.7.0 nor 2.9.0.

[Vidar Berg]

Hi,

I see. Yes, that makes sense. Could you make a zip of the direct_test_mode folder in D:/sw/test54Hello/direct_test_mode and upload it here so I can try to find out why the project fails to build?

[Georg Jahnen]

Hi Vidar,

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

Please have a look at it

Best regards
Georg5367.direct_test_mode.zip

[Vidar Berg]

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

[Georg Jahnen]

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

[Georg Jahnen]

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

[Georg Jahnen]

I gave up with DTM

[Vidar Berg]

Sorry to hear that. I thought it was working after your previous comment.
