Hello,
I have set the device advertising as follows:
static void advertising_init(void)
{
ret_code_t err_code;
ble_advdata_t advdata;
ble_advdata_t srdata;
ble_gap_adv_params_t adv_params;
ble_uuid_t adv_uuids[] = {{LBS_UUID_SERVICE, m_lbs.uuid_type}};
// Build and set advertising data.
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_FULL_NAME;
advdata.include_appearance = true;
advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
memset(&srdata, 0, sizeof(srdata));
srdata.uuids_complete.uuid_cnt = sizeof(adv_uuids) / sizeof(adv_uuids[0]);
srdata.uuids_complete.p_uuids = adv_uuids;
err_code = ble_advdata_encode(&advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);
#ifdef DEBUG
printf("ble_advdata_encode%d\n",err_code);
#endif
APP_ERROR_CHECK(err_code);
err_code = ble_advdata_encode(&srdata, m_adv_data.scan_rsp_data.p_data, &m_adv_data.scan_rsp_data.len);
#ifdef DEBUG
printf("ble_advdata_encodesrdata%d\n",err_code);
#endif
APP_ERROR_CHECK(err_code);
// Start advertising.
memset(&adv_params, 0, sizeof(adv_params));
adv_params.p_peer_addr = NULL;
adv_params.filter_policy = BLE_GAP_ADV_FP_ANY;
adv_params.interval = APP_ADV_INTERVAL;
adv_params.properties.type = BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED;
adv_params.duration = APP_ADV_DURATION;
adv_params.primary_phy = BLE_GAP_PHY_1MBPS;
err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &adv_params);
#ifdef DEBUG
printf("sd_ble_gap_adv_set_configure%d\n",err_code);
#endif
APP_ERROR_CHECK(err_code);
}
Advertising name is getting broadcasted with a full name until it gets changed and to 4 letters device name. In my application, there is a need for changing the advertising name for 5 min duration and that name is of 4 characters only. That gets advertised successfully. But the problem arises after again changing to the first advertising name, which has more than 4 letters. It does not get advertised with full name only the first 4 characteristics get advertised.
Advertising init function is used every time I changed the advertising name which has full name advertising settings. My first name is "LED_BUTTON"(10 characters) and the second name is "TEST"(4 characters). I want to switch the first name with 2nd for 5 min and again to first. Below code shows how i have changed name:
ret_code_t err_code = sd_ble_gap_adv_stop(m_adv_handle);
APP_ERROR_CHECK(err_code);
err_code = sd_ble_gap_device_name_set(&sec_mode,(const uint8_t *)DEVICE_NAME,strlen(DEVICE_NAME));
APP_ERROR_CHECK(err_code);
advertising_init();
err_code = sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
APP_ERROR_CHECK(err_code);
What should i do for advertising with full name after changing advertising name dynamucally in code for 5 min.
