https://devzone.nordicsemi.com/f/nordic-q-a/70604/how-to-put-the-output-file-back-inHi, I am developing using Segger Embedded Studio. I downloaded the module and checked that output/debug/Exe has a .hex file. Then can I download this output file back to the module? I wonder if it works the same way if possible.
