                        Serial DFU for nrf52840
Hi ,
I am trying to do the usb-serial dfu of nrf52840 but I am stuck at it. I can do it using the bluefruit library and the USB serial example from the nrf SDK but the hex file from my n-able based code doesn't work it I use it in the serial dfu.
If anyone have any insights on this, any help is much appreciated, Thanks
Are you using the adafruit bootloader? If so you'll need to select it as the uploader to flash.
