DTM doesn't work on nRF52840 dongle

[yoelbn83]

Hi,

I have the nRF52840 dongle (PCA10059) and I want to use it with the nrf connect program as DTM.

When I choose the option of DTM I get this message 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

I tried RSSI viewer and it works fine.

Anyone knows why DTM doesn't work?

Hi 

The DTM example is not set up to run on the dongle unfortunately, only on the nRF52840DK. 

Do you have a DK available that you can test with?

Best regards

Good luck. If you have problems with it just let me know, and I will do my best to help

Can the DTM example be ported to the dongle?  I assume so, since it can work as a sniffer.  I have looked for the sniffer source to use as a template but looks like that might be closed source.

Hi

Some code is shared in this case attempting to set up the nRF52840 dongle running DTM over USB. Please note it is made for an older version of the nRF5 SDK. 

The sniffer source code is not available, that is correct. 

Best regards
