Hi Nordic ,
I have a nRF52840 project development based on SDK 15.3 . Now ,I need to add DFU feature there. we suppose to use background DFU here. we will use long range( coded PHY S8), and long connection parameter .
form my study ,I can use IOT bootloader example from my bootloader.
but about the DFU function, can you give me the hint and reference for DFU function implement ?
I am not idea on how to save the New fw package during the application status now. Thanks.
