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!

Hi Bernd,

nRF Connect for Desktop v1.x only supports Secure DFU, i.e. the bootloader examples from SDK v12.x.0. Thus, if you want to perform Legacy DFU (SDK v11.0.0 and older) then you'll have to use nrfutil v0.5.2, here is the link.

Best regards

Ok, thanks! But the following error message is shown (last line) "TypeError: init() got an unexpected keyword argument 'dfu_version'", DFU Version is 0.5 (in the manifetst). The package is generated with nrfutil (version 0.3.0), Commandline: nrfutil.exe dfu genpkg --application package.bin --application-version 0xFFFFFFFF --dev-type 0xFFFF --dev-revision 0xffff --sd-req 0xFFFE package.zip
