PCA10059 USB nRF52840 Dongle Direct Mode Test Inquiry

[ywmw]

I am all new to nRF52480 dongle, would like to use Direct mode test getting error message in Direct Test Mode software (v2.0.3).

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.

During testing, only run Direct mode test software. Dongle information as below:

PCA10059

2.1.1

Please kindly help to advise where I could get direct test mode firmware or other fixes can resolve this issue.

Thanks a lot!!

Hello,

Really sorry you won't be able to find a direct sample/firmware for 52840 dongle in our SDK. One way you can do DTM test with dongle is to adapt 52840dk sample and modify it for 52840dongle,  for doing the same you can refer  this blog.

In this ticket, My colleague has shared a file using USB and DTM. Keep this as a reference and  this thread and SDK used looks quite old. So I don't guarantee that it's a complete working model. Just keep it for your reference.

I checked your log, what version of the JLINK are you trying and how are you programming the dongle. Are you connecting it directly to the PC?

Sorry for  the response time I took. We are less in numbers due to Christmas vacation. So please expect some delay from my side.

Kind Regards,

Abhijith

Dear Abhijith,

R&D colleague purchased a 52840DK for test evaluation.

It comes with a demo FW on board when powered up.  Please advise where we can download the hex file of this demo FW in case we would like to restore back after testing other projects.

Thanks in advance for the support!
