hi in tutoriall service beginer there is
static void advertising_init(void)
{
uint32_t err_code;
ble_advdata_t advdata;
// Build advertising data struct to pass into ble_advertising_init().
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
ble_adv_modes_config_t options = {0};
options.ble_adv_fast_enabled = BLE_ADV_FAST_ENABLED;
options.ble_adv_fast_interval = APP_ADV_INTERVAL;
options.ble_adv_fast_timeout = APP_ADV_TIMEOUT_IN_SECONDS;
// OUR_JOB: Create a scan response packet and include the list of UUIDs
ble_uuid_t m_adv_uuids[] = {BLE_UUID_OUR_SERVICE, BLE_UUID_TYPE_VENDOR_BEGIN};
ble_advdata_t srdata;
memset(&srdata, 0, sizeof(srdata));
srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
srdata.uuids_complete.p_uuids = m_adv_uuids;
err_code = ble_advertising_init(&advdata, &srdata, &options, on_adv_evt, NULL);
APP_ERROR_CHECK(err_code);
}
and in sdk v6 for nrf51422 v2 there is no ble_advertising_init() but there is ble_advdata_set() and i use it like below
static void advertising_init(void)
{
uint32_t err_code;
ble_advdata_t advdata;
uint8_t flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
ble_advdata_t srdata;
ble_uuid_t adv_uuids[] =
{
{BLE_UUID_HEART_RATE_SERVICE, BLE_UUID_TYPE_BLE},
{BLE_UUID_BATTERY_SERVICE, BLE_UUID_TYPE_BLE},
{BLE_UUID_DEVICE_INFORMATION_SERVICE, BLE_UUID_TYPE_BLE}
};
ble_uuid_t m_adv_uuids[] = {BLE_UUID_OUR_SERVICE, BLE_UUID_TYPE_VENDOR_BEGIN};
memset(&srdata, 0, sizeof(srdata));
srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
srdata.uuids_complete.p_uuids = m_adv_uuids;
// Build and set advertising data.
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = true;
advdata.flags.size = sizeof(flags);
advdata.flags.p_data = &flags;
advdata.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
advdata.uuids_complete.p_uuids = adv_uuids;
err_code = ble_advdata_set(&advdata,&srdata);
APP_ERROR_CHECK(err_code);
// Initialize advertising parameters (used when starting advertising).
memset(&m_adv_params, 0, sizeof(m_adv_params));
m_adv_params.type = BLE_GAP_ADV_TYPE_ADV_IND;
m_adv_params.p_peer_addr = NULL; // Undirected advertisement.
m_adv_params.fp = BLE_GAP_ADV_FP_ANY;
m_adv_params.interval = APP_ADV_INTERVAL;
m_adv_params.timeout = APP_ADV_TIMEOUT_IN_SECONDS;
}
but it return error NRF_ERROR_INVALID_PARAM 0x00000007 when i comment this line out
srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
the error will gone then the problem is this line
why?
