I get error.

Function sd_ble_gap_sec_params_reply(m_conn_handle, BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP, NULL, NULL) return error 8.

Help me.

Bootloader installed to flash memory. Why do not start bootloader?

YEs, that is the intended behaviour. The chip should perform a SystemReset so that it enter the bootloader, which is always started before the application when it is present on the chip.

ble_dfu_buttonless_bootloader_start_finalize -> nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_DFU) -> nrf_pwr_mgmt_shutdown(nrf_pwr_mgmt_shutdown_t shutdown_type) -> shutdown_process(void).

static void shutdown_process(void)

execution enters in the block

if ((m_pwr_mgmt_evt == NRF_PWR_MGMT_EVT_PREPARE_RESET)
|| (m_pwr_mgmt_evt == NRF_PWR_MGMT_EVT_PREPARE_DFU))
{
NVIC_SystemReset();
}

And occurs System Reset.

Alex, when you report that functions return errors, then you need to provide the error codes so that we can find out what caused the error. Also do you mean a compilation error or a run-time error?

After calling the ble_dfu_buttonless_bootloader_start_finalize() function the device should jump to the bootloader and the device should start advertising as DfuTarg. You can then connect to the device using nRF Connect for Desktop or Mobile(ios/Android) and then start a DFU by pressing the DFU icon, the blue lock and then select the image you want to upload

I modify RAM start and RAM STOP in IAR.

after started project.

How do start work DFU? I use function ble_dfu_buttonless_bootloader_start_finalize(); but she not started DFU.

Error on line nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_DFU); in function

0x04 means NRF_ERROR_NOMEM, which is generate by sd_ble_uuid_vs_add when there are no more free slots for VS UUIDs,

You need to increase NRF_SDH_BLE_VS_UUID_COUNT in sdk_config.h to 1.

Which error code is returned by ble_dfu_buttonless_init()? Can you step into ble_dfu_buttonless_init and see which internal function that returns the error code?

bootloader uploaded

RE: Tutorial on setting up the bootloader for nrf52832 in IAR

bjorn-spockeli — Wed, 16 Jan 2019 16:05:43 GMT

You call the following function

uint32_t ble_dfu_buttonless_bootloader_start_finalize(void)
{
    uint32_t err_code;

    NRF_LOG_DEBUG("In ble_dfu_buttonless_bootloader_start_finalize\r\n");

    err_code = sd_power_gpregret_clr(0, 0xffffffff);
    VERIFY_SUCCESS(err_code);

    err_code = sd_power_gpregret_set(0, BOOTLOADER_DFU_START);
    VERIFY_SUCCESS(err_code);

    // Indicate that the Secure DFU bootloader will be entered
    m_dfu.evt_handler(BLE_DFU_EVT_BOOTLOADER_ENTER);

    // Signal that DFU mode is to be enter to the power management module
    nrf_pwr_mgmt_shutdown(NRF_PWR_MGMT_SHUTDOWN_GOTO_DFU);

    return NRF_SUCCESS;
}

its defined in ble_dfu.c and its called in so just include ble_dfu.h in the file, I assume main.c, and then call ble_dfu_buttonless_bootloader_start_finalize when you want to jump to the bootloader.

I solved the compilation problems. I changed the function "services_init(void)" of project ble_app_uart 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);

   //**************************
}

and add peer_manager_init

int main(void)
{
    bool erase_bonds;
    
  //  static uint32_t pages_to_erase = 1;
    
    // Initialize.
    log_init();
    timers_init();
    buttons_leds_init(&erase_bonds);
    power_management_init();
    ble_stack_init();
    peer_manager_init();
    gap_params_init();
    gatt_init();
    services_init();
    advertising_init();
    conn_params_init();

    // Start execution.
    
    advertising_start(erase_bonds);

I want start buttonless DFU with command. I get command through ble uart. How do I may it make?

RE: Tutorial on setting up the bootloader for nrf52832 in IAR

bjorn-spockeli — Wed, 16 Jan 2019 13:32:00 GMT

Just use the second one, i.e. advertising_start(bool erase_bonds), with erase_bonds = false.

RE: Tutorial on setting up the bootloader for nrf52832 in IAR

Alex_Golubev — Wed, 16 Jan 2019 11:23:20 GMT

In project ble_app_uart function advertising_start have the form

static void advertising_start(void)
{
    uint32_t err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
    APP_ERROR_CHECK(err_code);
}

In project ble_app_buttonless_dfu function advertising_start have the form

static void advertising_start(bool erase_bonds)
{
    if (erase_bonds == true)
    {
        delete_bonds();
        // Advertising is started by PM_EVT_PEERS_DELETE_SUCCEEDED event.
    }
    else
    {
        uint32_t err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
        APP_ERROR_CHECK(err_code);

        NRF_LOG_DEBUG("advertising is started");
    }
}

Which do one to use function advertising_start ?

RE: Tutorial on setting up the bootloader for nrf52832 in IAR

bjorn-spockeli — Wed, 16 Jan 2019 10:29:32 GMT

No, unfortunately we do not have such a guide.

I suggest that you compare the project settings of your ble_app_uart project IAR project with the settings of the ble_app_buttonless_dfu IAR project. You will then see which .c files that are nescessary , which paths to .h files that must be added to the include directories path and which Preprocessor definitions that are needed.

RE: Tutorial on setting up the bootloader for nrf52832 in IAR

I build project.

I added peer_id.c, peer_data_storage.c, peer_database.c, peer_manager.c, pm_buffer.c, pm_mutex.c, security_dispatcher.c, security_manager.c, gatt_cache_manager.c, gatts_cache_manager.c,id_manager.c include in sdk_config.h CRC16_EABLE, FDS_ENABLE, NRF_DFU_BLE_BUTTONLESS_SUPPORTS_BONDS, NRF_SDH_BLE_SERVICE_CHANGED and BLE_DFU_ENABLED and added BL_SETTINGS_ACCESS_ONLY, NRF_DFU_SVCI_ENABLED
NRF_DFU_TRANSPORT_BLE=1

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

What do I must make for full completions buttonless DFU?

If you flash SoftDevice, Bootloader and the Buttonless DFU application, then the device should start in DFU mode. If you want the device to run the application, then you need to generate a bootloader settings page and flash that along with the SD,BL and App.

See https://github.com/NordicSemiconductor/pc-nrfutil#generate-2 on how to generate the settings hex file.

I did the secure bootloader DFU. I attained step 8 in document.

I instal softdevice and secure bootloader to flash nRF52832. After make the ble_app_buttonless_dfu start download and debug but program not start.

If install only softdevice and buttonless dfu then I got error "No bootloader was found".

If install softdevice and bootloader after buttonless dfu then I got not start programs.

Although security bootloader work.
The verification was performed in the following steps:

E1. Generate new firmware.

E2. Generate new DFU .zip package.

E3. Switch the device to DFU mode, do DFU update and verify new image is running.

YEs, so its ble_dfu_buttonless_async_svci_init that returns a non-zero error code. This is usually due to the bootloader not being flashed to the nRF52. Compile the bootloader example and flash it to the nRF52 in addition to the buttonless dfu example and the S132 softDevice. See the documentation on the bootloader example.
