Exactly which function is it that returns NRF_ERROR_CONN_COUNT. Is it returned when you receive a connection request from a central, or does it return when you try to advertise and the max link count is already reached.

Hi Jared, thanks for the reply, but I am still facing the same issue after added m_advertising.initialized = true. After my device reached the max link count it is still connecting to central nodes returning NRF_ERROR_CONN_COUNT, I want to keep my device advertising, but in non-connectable way being unable to do it in the latest SDK version

Sorry for the late response.

Could you try setting initialized = true before you call the ble_advertising_init()?:

m_advertising.intialized = true;

err_code = ble_advertising_init(&m_advertising, &init);

I tried using the following and it is updating my advertising data, but I am still unable to set the peripheral scannable non-connectable

		BLE_ADVERTISING_DEF(m_advertising); /**< Advertising module instance. */
		...
		
		uint8_t update_advertising_data()
		{
			uint32_t err_code = NRF_SUCCESS;
			ble_advertising_init_t 		init;
			ble_advdata_t				advert; 
			ble_advdata_t				scanrsp;
		
			memset(&advert, 0, sizeof(advert));
			advert.flags						= BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
			advert.p_tx_power_level				= &txpower;
			
			memset(&scanrsp, 0, sizeof(scanrsp));
			scanrsp.name_type				    = BLE_ADVDATA_FULL_NAME;
			
			memset(&init, 0, sizeof(init));
			init.advdata						= advert;
			init.srdata							= scanrsp;
			init.config.ble_adv_fast_enabled	= true;
			init.config.ble_adv_fast_interval	= MSEC_TO_UNITS(advertisinginterval, UNIT_0_625_MS); 
					
			if (NRF_SDH_BLE_PERIPHERAL_LINK_COUNT)	
				m_advertising.adv_params.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_SCANNABLE_UNDIRECTED; 
			else
				m_advertising.adv_params.properties.type = BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED; 
			
			err_code = ble_advertising_init(&m_advertising, &init);
			APP_ERROR_CHECK(err_code);
			ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);	
			
			err_code = ble_advdata_encode(advert, m_advertising.enc_advdata, &m_advertising.adv_data.adv_data.len);
			APP_ERROR_CHECK(err_code);

			err_code = ble_advdata_encode(scanrsp, m_advertising.enc_scan_rsp_data, &m_advertising.adv_data.scan_rsp_data.len);
			APP_ERROR_CHECK(err_code);
			
			
			return ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);
		}

actually, I don't have issues updating the advertising data or handle, my problem is I am unable to change the adv_params.properties.type to change my device between scannable connectable and scannable non-connectable, when I add it to sd_ble_gap_adv_set_configure I got the error above, and when it is not added when I reach the connection limit my device tries to connect again returning NRF_ERROR_CONN_COUNT. After the link count is reached I want my device keep advertising scannable non connectable, when I have link counts available advertisie the device it is scannable connectable

How can I set ble_gap_adv_params_t properties.type when using the SDK15?

Hi,

The NRF_ERROR_NO_MEM is returned when there is not enough memory to configure a new handle. You should update the existing advertising handle instead.
