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.

@AD1170: If there is no confidential info you can upload your log here by editing your question.

I would need you to make sure you can use the MCP and nRF51DK without problem. Leave DFU aside, could you try to test any example in the SDK, ble_app_hrs for example, and keep them connected for a few minutes.

" the connection is terminated during the service discovery" => Please attach log.

Please try to test with just the DFU bootloader, don't flash your application. Try to do a DFU with application image from one of our example.

Which SDK are you using ? We don't have SDK v8.9.
