ble_stack_init question

[gercer]

Hello

I'm trying to implement whitelist in my code and i found a post which has the following code for the ble_stack_init function:

static void ble_stack_init(void)
{
uint32_t err_code;

nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC;

SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL);

ble_enable_params_t ble_enable_params;
err_code = softdevice_enable_get_default_config(CENTRAL_LINK_COUNT,
PERIPHERAL_LINK_COUNT,
&ble_enable_params);
APP_ERROR_CHECK(err_code);

//Check the ram settings against the used number of links
CHECK_RAM_START_ADDR(CENTRAL_LINK_COUNT,PERIPHERAL_LINK_COUNT);

// Enable BLE stack.
ble_enable_params.gatts_enable_params.service_changed = IS_SRVC_CHANGED_CHARACT_PRESENT;
err_code = softdevice_enable(&ble_enable_params);
APP_ERROR_CHECK(err_code);

err_code = softdevice_ble_evt_handler_set(ble_evt_dispatch);
APP_ERROR_CHECK(err_code);

err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);
APP_ERROR_CHECK(err_code);
}

The ble_app_hids_keyboard example has the following code for the same function:

static void ble_stack_init(void)
{
    ret_code_t err_code;

    err_code = nrf_sdh_enable_request();
    APP_ERROR_CHECK(err_code);

    // Configure the BLE stack using the default settings.
    // Fetch the start address of the application RAM.
    uint32_t ram_start = 0;
    err_code = nrf_sdh_ble_default_cfg_set(APP_BLE_CONN_CFG_TAG, &ram_start);
    APP_ERROR_CHECK(err_code);

    // Enable BLE stack.
    err_code = nrf_sdh_ble_enable(&ram_start);
    APP_ERROR_CHECK(err_code);

    // Register a handler for BLE events.
    NRF_SDH_BLE_OBSERVER(m_ble_observer, APP_BLE_OBSERVER_PRIO, ble_evt_handler, NULL);
}

Could you tell me the main difference between them?

Thank you!

Hi,

The main difference seems to be the SDK version, and the main difference is due to the reworked SoftDevice handler library. The first code snippet is from SDK 11, whereas the last seems to be from SDK version >= 14.0.0.
