I get error.

What do I do wrong?

In main.c you have to add the service for buttonless dfu:

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};
    ble_dis_init_t     dis_init;

    // 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);

#if defined(NDEBUG)
//***** 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);

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

    ble_bas_init_t bas_init;

}

What is the specific problem?

Hi Mdido

Can I have your integrated main.c and sdk_config.h file?

I have tried it so many times but still it is not working.

RE: buttonless DFU integration in BLE app uart example: compiling problem

mdido — Fri, 01 Jun 2018 14:35:24 GMT

I have increased memory and it seems to work. Wow! What a hard job! I suggest you to make a guide or an application note on how to add the DFU service to a custom application..

Thanks for the support

Best regards

That is stated in the p_app_ram_start variable, or more correctly in the variable that p_app_ram_start points to, i.e. *p_app_ram_start . If you add p_app_ram_start to watch and then set a breakpoint after sd_ble_enable() you should be able to see which value points top_app_ram_start.

Take a look at this video, it explains how to modify the build settings, including the memory settings.

RE: buttonless DFU integration in BLE app uart example: compiling problem

mdido — Fri, 01 Jun 2018 14:04:52 GMT

Ok, but please could you tell me how to make it and how much memory to allocate.?

Thank you for the support

Yes, you need to increase the RAM allocated to the SoftDevice as stated in the RTT log output.

RE: buttonless DFU integration in BLE app uart example: compiling problem

mdido — Fri, 01 Jun 2018 13:33:31 GMT

I changed 1 in 2, but now in function:

ret_code_t nrf_sdh_ble_enable(uint32_t * const p_app_ram_start)
{
    // Start of RAM, obtained from linker symbol.
    uint32_t const app_ram_start_link = *p_app_ram_start;

    ret_code_t ret_code = sd_ble_enable(p_app_ram_start);
    if (*p_app_ram_start > app_ram_start_link)
    {
        NRF_LOG_WARNING("Insufficient RAM allocated for the SoftDevice.");

        NRF_LOG_WARNING("Change the RAM start location from 0x%x to 0x%x.",
                        app_ram_start_link, *p_app_ram_start);
        NRF_LOG_WARNING("Maximum RAM size for application is 0x%x.",
                        ram_end_address_get() - (*p_app_ram_start));
    }
    else
    {
        NRF_LOG_DEBUG("RAM starts at 0x%x", app_ram_start_link);
        if (*p_app_ram_start != app_ram_start_link)
        {
            NRF_LOG_DEBUG("RAM start location can be adjusted to 0x%x.", *p_app_ram_start);

            NRF_LOG_DEBUG("RAM size for application can be adjusted to 0x%x.",
                          ram_end_address_get() - (*p_app_ram_start));
        }
    }

    if (ret_code == NRF_SUCCESS)
    {
        m_stack_is_enabled = true;
    }
    else
    {
        NRF_LOG_ERROR("sd_ble_enable() returned %s.", nrf_strerror_get(ret_code));
    }

    return ret_code;
}

the the execution the execution enters in the block

    if (*p_app_ram_start > app_ram_start_link)
    {
        NRF_LOG_WARNING("Insufficient RAM allocated for the SoftDevice.");

        NRF_LOG_WARNING("Change the RAM start location from 0x%x to 0x%x.",
                        app_ram_start_link, *p_app_ram_start);
        NRF_LOG_WARNING("Maximum RAM size for application is 0x%x.",
                        ram_end_address_get() - (*p_app_ram_start));
    }

Increase the NRF_SDH_BLE_VS_UUID_COUNT from 1 to 2 in sdk_config.h

RE: buttonless DFU integration in BLE app uart example: compiling problem

mdido — Fri, 01 Jun 2018 12:51:08 GMT

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)"

RE: buttonless DFU integration in BLE app uart example: compiling problem

bjorn-spockeli — Fri, 01 Jun 2018 11:22:07 GMT

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?

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

RE: buttonless DFU integration in BLE app uart example: compiling problem

mdido — Fri, 01 Jun 2018 07:38:32 GMT

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?

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