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!

@Bernd: Are you the same account with AD1170 ?

Please post your log as a .txt file, it's easier to read that way.

Please described exactly the step you do for testing the bootloader. Note: only flash the bootloader then do DFU to update an example firmware. Please list the test step by step, starting with step 1. Flashing the softdevice.

I found it hard to understand what exactly you did with your description

"Here is the part of the log file where i connect to the alredy running bootloader on the device. The service discovery works but the DFU button is still disabled. Until i not discover the services, the connection is hold. After dicovering the services, the connection is terminted (the device perform a restart)." "

Please attach full log. It's not normal to have the bootloader disconnected just because of service discovery.

Yes, Bernd and AD1170 is the same account. Sorry, but i think we are going the wrong way. The DFU work's with nrfConnect / nrfToolbox on Android and iOS without any problem. So i think the my bootloader implementation is ok. What is the difference, or in other words, where is the problem. I have already spend a lot of time in communication and debgging. Why you do not support the legacy DFU with your new PC-nRFconnect like the Android/iOS implementation? Please tell me how i can upload a text file. I can only add a comment.... Thank you.

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.
