Changing device name dynamically

Question

Hi there, 
 
 I am using the nRF connect app on Android to see my dongle's name. I want the name to change every 5 seconds from one name to another. This is just for evaluation. 
 
 How can I do this? I am using SDK 15 with SD S140. I am using the LED button example. 
 
 A snippet of my code: 
 BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);
 sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)DEVICE_NAME_2, strlen(DEVICE_NAME_2));
 ble_advdata_encode(&advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);
 sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &adv_params);
 sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
 bsp_board_led_on(CONNECTED_LED);
 nrf_delay_ms(5000);
 BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);
 sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)DEVICE_NAME, strlen(DEVICE_NAME));
 ble_advdata_encode(&advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);
 sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &adv_params);
 sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
 bsp_board_led_off(CONNECTED_LED);
 nrf_delay_ms(5000);

I was able to get this working by doing something like this: static void setDeviceName(deviceStatus_t status)
{
 ble_gap_conn_sec_mode_t sec_mode;
 BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);
 
 // Set the device name
 switch(status)
 {
 case STATUS_LOW:
 sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)DEVICE_NAME_LOW, strlen(DEVICE_NAME_LOW));
 bsp_board_led_on(BSP_BOARD_LED_1);
 break;
 case STATUS_MED:
 sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)DEVICE_NAME_MED, strlen(DEVICE_NAME_MED));
 bsp_board_led_on(BSP_BOARD_LED_3);
 break;
 case STATUS_HIGH:
 sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)DEVICE_NAME_HIGH, strlen(DEVICE_NAME_HIGH));
 bsp_board_led_on(BSP_BOARD_LED_2);
 break;
 case STATUS_ERR:
 sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)DEVICE_NAME_ERR, strlen(DEVICE_NAME_ERR));
 bsp_board_led_on(BSP_BOARD_LED_0);
 break; 
 }

 // Encode the advertising packet and start advertising
 ble_advdata_encode(&advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);
 sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &adv_params);
 sd_ble_gap_adv_stop(m_adv_handle);
 sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
}
