I can update firmware in my nRF52 nodes using DFU where on the other end I have Android phone or nRF Connect (PC/Windows)+PCA10040. Everything works fine. But in my application I want to use nRF52 based node ("central" in my system) to update other nRF52 nodes ("peripherals"). My central is equipped with external SPI FLASH to keep new image/images.
I can't find example even close to my application (nRF52 ->DFU-> nRF52), everything works with zipped packages. Am I alone with this type of application?
