DFU OTA - image not confirmed

[PingISTL]

Dear support

I am develop another application to use DFU OTA - I have already done 1 and successful so far. I think i better generate a new key file as this is a different product, so I did. But when I try to the test using Device Manager App. it ends up with an error message - "image not confirm ", I tried to read images and it does have two images there, so downloaded fine, just not confirmed, so not be able to update the firmware.

Any suggestions please? is it OK to generate two different key (.pem) files use same toolchain?

Thanks!

Dear All

I tested again this morning, don't think it is related to the new key file, as I tried to use old key and still not working. But the first project works, and there is no major difference in terms of configuration. all use nrf Connect v2.1.0 for VS code.

This seems very much like the issue mentioned here. Can you check your static configuration as suggested in the thread I linked.

Dear Susheel 

Thanks for reply, I forgot to mention, we are not developing our download application, instead just using the Device Manager for Mobile app from Nordic. In that case, how do I config the static configuration you mentioned above?

Regards!
