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.

You can edit your question to add your attachment there.

I would suggest you if possible record a video clip when you do testing with nRF Master Control Panel. Then attache the log you have on that session. This way I would know what happen exactly. (You can upload it to youtube or elsewhere)

A sniffer trace would be also very useful.

Please also attach:

• Your bootloader hex file

• Your application hex file (you can test with any example in the SDK , it's easier)

• Your DFU .zip file

Make the DFU on nRFConnect backward compatible would be added in the backlog, I will report your request.
