Unable to use the DTM example for nRF5340 DK (PCA10095)

[ShuMan]

I am trying to use the DTM example for nRF5340 DK (PCA10095). The example is located at "C:\v1.7.0\nrf\samples\bluetooth\direct_test_mode", but I am facing "NRF_RADIO_Type" error along with few more errors with 1.7.0 as well as 1.9.0 SDK. I have attached the error log files' links below.

SDK 1.7.0 error log: https://drive.google.com/file/d/1m75QjX6ug_ym6KEYMkzjd8zMPitysDJz/view?usp=sharing

SDK 1.9.0 error log: https://drive.google.com/file/d/1epy6gnY7Dz73dMOb64afPjl9ZBsMckIp/view?usp=sharing

I have also tried using SDK 1.9.1, however I am unable to open the DTM project in it.

Thanks.

Hi,

I have tested Direct Test Mode (DTM) sample and did not have any issues with building the sample neither in NCS v1.7.0 nor in v1.9.0.

Please ensure that the board you choose is nrf5340dk_nrf5340_cpunet as described in  direct test mode.
Based on the FEM support and hardware support, if you use nrf21540_ek, you should add extra CMAKE argument -DSHIELD=nrf21540_ek when adding build configuration.

Best regards,
Dejan

Hi dejans, 

Thanks for the clarification. I am now able to build and download the the sample into the DK. However, I am not able to use the DTM as I am getting the error "Can not communicate with device. Make sure it is not in use by another application and that it has a Direct Test Mode compatible firmware".

My setup: First chose the nrf5340dk_nrf5340_cpunet and direct_test_mode example, build and load the DTM firmware onto my PCA10095 via USB connector. Next, I select the COM port for my serial connection in nRF connect DTM app. Finally, I press the "Start Test" button at the bottom of the DTM section and then the error comes up.

Thanks and Regards.

Hi,

You would need to connect to the device which should be available under "Select Device" in the upper-left corner of the Direct Test application.

Best regards,
Dejan

Hi dejans , 

I'm seeing the same issue. I've updated pin configs in the board's .dts and .dtsi files for both net and app cores but no luck. How do I change/reassign the UART pins from within the DTM project itself?

Thanks

Hi,

Which NCS version do you use?

Could you provide more information about "no luck"? Did you get any errors? If so, could you provide a log?

Best regards,
Dejan
