nRF5 SDK possible to OTA update to nRF Connect SDK?

[KLLiew]

Hi,

Just need a quick checking on this.

Currently we using nRF5 SDK, after production, is it possible we OTA update the firmware which using nRF Connect SDK?

This very important for us to decide our roadmap of development.

Thank you

Best Regards,

Alan

Good timing with this question. We are also interested in the same thing.

We currently have ~500 nRF52832 devices in the field running nRF5 SDK. These are typically remotely updated over UART DFU to perform firmware upgrades using nRF5 SDK.

We would like to migrate future devices to NCS (nRF Connect SDK), and ideally, update those existing devices in the field to the NCS-based application.

Is this possible using the existing nRF SDK UART DFU Bootloader?

If so, does the existing nRF bootloader and MCUBoot bootloader coexist afterwards?

I think it is possible, but I need time to try.

 No.

Thanks for your reply, Amanda.

I am very interested to hear if this is possible using the nRF5 SDK UART DFU bootloader. I will be attempting it at some point so I would appreciate any instructions you can give similar to your post to KLLiew

I thought updating devices from nRF5 SDK to NCS over DFU would be a common request by users so perhaps it could deserve a blog post or an app note.
