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???

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?

[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?

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

[mdido]

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

Thank you for the support

[bjorn-spockeli]

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.

[mdido]

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

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.

[mdido]

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);

//**************************
#endif

//************ Battery Service *********************
    ble_bas_init_t bas_init;
    memset(&bas_init, 0, sizeof(bas_init));
    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&bas_init.battery_level_char_attr_md.cccd_write_perm);
    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&bas_init.battery_level_char_attr_md.read_perm);
    BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(&bas_init.battery_level_char_attr_md.write_perm);

    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&bas_init.battery_level_report_read_perm);

    bas_init.evt_handler = NULL;
    bas_init.support_notification = true;
    bas_init.p_report_ref = NULL;
    bas_init.initial_batt_level = 100;

    err_code = ble_bas_init(&m_bas,&bas_init);
    APP_ERROR_CHECK(err_code);
 //****************************************************

    memset(&dis_init, 0, sizeof(dis_init));

    ble_srv_ascii_to_utf8(&dis_init.manufact_name_str, (char *)MANUFACTURER_NAME);
    ble_srv_ascii_to_utf8(&dis_init.fw_rev_str, (char *)SW_REV);
    ble_srv_ascii_to_utf8(&dis_init.sw_rev_str, (char *)SW_REV);

    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&dis_init.dis_attr_md.read_perm);
    BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(&dis_init.dis_attr_md.write_perm);

    err_code = ble_dis_init(&dis_init);
    APP_ERROR_CHECK(err_code);
 //**************************************************************

}

What is the specific problem?
