buttonless DFU integration in BLE app uart example: compiling problem

[mdido]

I'm trying to integrate buttonless DFU in BLE app uart example. I added the file: ble_dfu.c, ble_dfu_bonded.c, ble_dfu_unbonded.c in the project. I added the following folder:

C:\Nordic_Semi\nRF5_SDK_15.0.0_a53641a\components\libraries\svc

C:\Nordic_Semi\nRF5_SDK_15.0.0_a53641a\components\libraries\bootloader\dfu

C:\Nordic_Semi\nRF5_SDK_15.0.0_a53641a\components\libraries\bootloader

C:\Nordic_Semi\nRF5_SDK_15.0.0_a53641a\components\ble\ble_services\ble_dfu

C:\Nordic_Semi\nRF5_SDK_15.0.0_a53641a\components\libraries\bootloader\ble_dfu

in Preprocessor->User include Directories (in Options of the project). I'm using segger embedded studio.

I've got several compilation errors:

There is a guide or an application note that explains the several steps needed to integrate buttonless DFU to a custom application???

[mdido]

I solved the compilation problems. I'll try the functionality in the next days.

There are news regarding official documentation about integration of buttonless DFU to a custom application?

[mdido]

I solved the compilation problems. I changed the function "services_init(void)" of project app_uart_example in:

static void services_init(void)
{
    uint32_t           err_code;
    ble_nus_init_t     nus_init;
    nrf_ble_qwr_init_t qwr_init = {0};
    ble_dfu_buttonless_init_t dfus_init = {0};

    // Initialize Queued Write Module.
    qwr_init.error_handler = nrf_qwr_error_handler;

    err_code = nrf_ble_qwr_init(&m_qwr, &qwr_init);
    APP_ERROR_CHECK(err_code);

    // Initialize NUS.
    memset(&nus_init, 0, sizeof(nus_init));

    nus_init.data_handler = nus_data_handler;

    err_code = ble_nus_init(&m_nus, &nus_init);
    APP_ERROR_CHECK(err_code);

//***** buttonless DFU *****

    // Initialize the async SVCI interface to bootloader.
    err_code = ble_dfu_buttonless_async_svci_init();
    APP_ERROR_CHECK(err_code);

    dfus_init.evt_handler = ble_dfu_evt_handler;

    err_code = ble_dfu_buttonless_init(&dfus_init);
    APP_ERROR_CHECK(err_code);

//**************************


}

but in executio I've got error " NRF_BREAKPOINT_COND;" in function "__WEAK void app_error_fault_handler(uint32_t id, uint32_t pc, uint32_t info)"

There are news regarding official documentation about integration of buttonless DFU to a custom application?

Just in case someone else runs into the same compilation issues: 

As stated by mdido you have to add the following files to the project 

ble_dfu.c
ble_dfu_bonded.c
ble_dfu_unbonded.c
nrf_dfu_svci.c

You have to add the following paths to Preprocessor->User include Directories  the Common build configuration

../../../../../../components/libraries/bootloader
../../../../../../components/libraries/bootloader/ble_dfu
../../../../../../components/libraries/bootloader/dfu
../../../../../../components/libraries/svc

and lastly you need to add the following Preprocessor Defines

BL_SETTINGS_ACCESS_ONLY
NRF_DFU_SVCI_ENABLED
NRF_DFU_TRANSPORT_BLE=1

[bjorn-spockeli]

mdido: We do not have an official guide on how to add the DFU service to a custom application. 

If you're entering the app_error_fault_handler function then there is probably a APP_ERROR_CHECK(err_code) check that is asserting. Could you place a breakpoint in app_error_handler_bare() in app_error.c and take a look at the call stack to see which function that caused the assert?

I can't place a breakpoint app_error_handler_bare(), the IDE tell me "no code for breakpoint".

In debugging I've got "NRF_ERROR_NO_MEM" form function "sd_ble_uuid_vs_add(&nordic_base_uuid, &m_dfu.uuid_type);" in "uint32_t ble_dfu_buttonless_init(const ble_dfu_buttonless_init_t * p_dfu_init)"
