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!

MCP should work with any nRF51 and nRF52 DK. Could you try with the DK ?

nRFConnect doesn't support legacy DFU.

Note that the DFU code that MCP uses is written in python and you can see and use the source code inside C:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.10.0.14\lib\nordicsemi\dfu .

You may think of using the python code directly.

I seems to be the bootloader on the device is started, the connection by MCP ist lost (due to invoking the bootloader) and there is no new connection establishment to the DFU device. Than i have try to connect to the already running DFU, but the connection is terminated during the service discovery. Perhaps it is better to convert this conversation to a support case? The benefit is, i can send you log - files or screen shots.
