Thanks for the reply.

Have you made any progress on the DFU server? If it really works, perhaps we will have to implement a DFU server as well.

Thanks

Best wishes

NrfUtil 4.0.0 is still having some problem as we have encountered in the past it was not reliable. Eventually we switched to our own implementation of the DFU server over thread protocol.

BTW, I am using the sdk for thread 2.0.0 and the latest nrfutil (4.0.0) and pca10056 board

Hi Peeyush

Happy new year!

Has this problem been resolved? I have encountered the same issue as you stated. Could you please share some idea with me if you have resolved the issue.

Thanks a lot

please try with new SDK2.0 and nrfutil4.0.0.. these have been released yesterday itself. I am facing the same issue you can try on DK and let me know I have 4 of these.

Peeyush,

I am using DK and do not have any PDKs with me.

I am strongly suspecting this has to do something with nrfutil which is the tool you used to generate the hex file. Something might have gone wrong there with signing the HEX file.

Please try it out with the latest nrfutil and nrfjprog versions.

I had tried on linux first..then moved to PC.. I agree with you..if you can share your tools version then it should be useful to us. How ever I have noticed one thing the client is not being able to print the IP addresses properly.

Let me know if you are using DK or PDK for testing this setup.

Thanks

Hi Peeyush,

At this point it is not clear if the problem is in the nrfutil or in the SDK.

Seems like you are running windows and we do not see big issues like this with nrfutil on Windows.

I will try to follow that guide and see if it fails the same way as you on my desk and then try to debug it from there on Monday. (hopefully that is OK)

Meanwhile i strongly recommend you to upgrade your nrf tools to latest and greatest.
