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

Yes, i'm talking about nrfConnect PC. The MCP work only with the small dongle (as far as i know). I have tried the update via MCP but it does not work. I can select the update package but the data upload fails. The update from Andoid mobile device works without problems (e.g. using nrfToolbox -> DFU). As i mentioned at the beginning. We are in production and we need a solution to update the firmware on stocked parts. The update must performed using a PC due to the neccessary update in the production device database. The solution with the nrfutil is good (if they works). It can be called from the over laying production software if the firmware version does not match.
