Question about Over the Air update in NCS_V2

[Midhunjac]

Does the NCS V2 .x support OTA updates ? I used OTA update with encryption in older SDK and i was looking to migrate that to the new SDK. Is there some example or  guide to how to do the exact same implementation in NCS ? I know NCS uses mcuboot but does that mean that DFU and OTA is no longer supported in NCS ?

Thank you.

Hi Midhunjac,

NCS v2.x supports OTA updates.

If you are asking if NCS v2.x support the same OTA solution as the nRF5 SDK, then no.

If you are asking if a nRF5 SDK device can be OTA upgrade to a NCS firmware, then theoretically yes. However, there are no official documentations and samples for it.

Hi, Thanks for the reply.

I have upgraded my device to the NCS based application. I now need to run OTA updates on this. Is there some kind of guide which I can use as a starting point for my purpose ? I understand that the solution may not be the exact same as the one in NRF5 but that is okay. I am willing to make changes. I just need some documentation or example to use as a reference. Is there something like that ?

As you say you are moving from the nRF5 SDK, I assume you want DFU over BLE when you say OTA.

There are two resources you can refer to for adding DFU over BLE:
- Zephyr SMP Server sample, where you can enable BLE support.
- Our colleague Simon's guide, with instructions to add DFU to a BLE application.

Okay. Thanks. I'll take a look at these and come back if I have any questions. Thanks again !!
