Hi, i can say that i'm familiarized with nrf51 devices from some time ago. Using softdevice 7.1.0 and MCP 3.7.1 i was able to perform a device firmware upgrade using just a single .hex. With master control panel v3.8.0 i start to get some problems when use DFU. Now, instead of input a single .hex file with my application, bootloader or softdevice i need to give a zip file containing files that, honestly, i don't why they are needed.
So, my question is why Nordic have done this harder to accomplish?
