nrfConnect - DFU Option not shown but DFU Service is running

[AD1170]

Hello,

i try to use the nrfConnect (PC version) to update my devices via DFU. The DFU service is running on the device (update with Andoid nrfToolbox works without any problems). But the nrfConnect SW does not show the DFU Button. Whats going wrong?

Thanks!

You're still using nrfutil v2.2.0 according to the error message. Did you download the v0.5.2 release from here?

Yes, i have used the v0.5.2.

@AD1170: Could you tell which error you get when you use v0.5.2, I would prefer a screenshot, you can edit the question to add picture.

Sorry, but i have noticed, that the version used for the DFU test was not the 0.5.2. The 2.2.0 was used instead. I have downloaded the v0.5.2. source package. But unfortunatelly the python script does not run. The package requirements was installed before. Might be this is due to the intalled nrfutil v2.2.0. I have not found any hint how to remove the previous installed version of nrfutil (in this case the v2.2.0).

The error messages are shown below:

Is there anywhere a executable version of the nrfutil v0.5.2, so that we can do this without the python environment? THX! PS: The edit function does not work for me.

@AD1170: If you only need to generate DFU package, you can use v0.3.0. We have an exe file. You can either install nRFGo Studio or nRF Master Control Panel (look for MCP).

nrfutil.exe is located in C:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.10.0.14\nrf or C:\Program Files (x86)\Nordic Semiconductor\nRFgo Studio
