Integrating Buttonless DFU: with extra custom 128bit UUID (SDK 12.x)

Steps 1, 2 and 3 need not be followed. Only Step 4 as such is enough to get the custom DFU application working. If anyone is facing any issues, I would be happy to help!

you need to #include "nrf_dfu_settings.h"

Hi Nguyen,

Are necessay any #include to use that snippet code? or Any aditional step to switch to DFU bootloader from the applicacion (e.g ble_app_uart example)

Thanks

It's a lot simpler. You don't need to add a custom dfu service for buttonless DFU. Just add these 2 functions snippet from the EHAL library to your code. Call the function BlePeriphAppEnterDfu(). It will automatically switch to DFU.

void BlePeriphAppDfuCallback(fs_evt_t const * const evt, fs_ret_t result)
{
    if (result == FS_SUCCESS)
    {
        NVIC_SystemReset();
    }
}

void BlePeriphAppEnterDfu()
{
    uint32_t err_code = nrf_dfu_flash_init(true);

    nrf_dfu_settings_init();

    s_dfu_settings.enter_buttonless_dfu = true;

    err_code = nrf_dfu_settings_write(BlePeriphAppDfuCallback);

    if (err_code != NRF_SUCCESS)
    {
    }
}
