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!
