BLE OTA DFU with RUI?

When creating a custom RUI application, how do you add DFU support to the BLE or is it natively supported once you switch BLE on and set to advertising mode?

After making a custom RUI application, I just need to use the nordic DFU app? How do I package the custom RUI application to be used for a DFU upgrade?

Is there a way to persist data on the RAK4600 module over a DFU update?

thanks!

Dear Steve,

Maybe you can refer DFU update to complete!

Best regards!

Thank you for the link but that link answered none of my questions. I know how to dfu update already. How it works with RUI is my question.

Dear Steve,

All you have to do is compile on the RUI platform, and the DFU file will be included in the zip download. You just need to download it.

Best regards!
