I am trying to package a firmware update and flash it over BLE DFU and I keep getting the following error on the nRF Toolbox app:
"Upload Failed: Unknown Command"

Generating the Settings hex:
Merging the settings hex with the bootloader hex:

Other information:
- Device: nRF52832
- SDK: 14.2.0
- Board: Custom
