• @Gordon so what will be the Make file command to create DFU package

    bootloader hex
    bootloader + softdevice hex

    When I use this command
    make clean &&
    NRF_SDK11=1
    DFU_UPDATE_BUILD=1
    BOARD=
    RELEASE=1
    USE_BOOTLADER=1
    VERBOSE=1 make

    and in BOARD.PY I have set
    'bootloader' : 1,

    It generates the DFU package just having Espruino application hex. The hex works perfect with a device which already have a valid bootloader installed.
