Hi King,

Whether you could implement the whitelist successsfully(with the address of the central deice)?..and advertise with the whitelist?

Whether it could connect successfully to that central only?

If yes, will you please share your code .

Currently I am up to this. still confused how to proceed.

Hi King,

You question tag says that you are using nrf51822 and then you confused me saying that you are using SDK0.9.1 (which is for nRF52)

You can just use directed advertising and implement BLE_ADV_EVT_PEER_ADDR_REQUEST. Please read about the advertising module here and use directed advertising instead of whitelist if you just want to send advertising to one know (unbonded) central

If you still want to use whitelist, then you can do it, but in your above code snippet, what happens is, that when the Advertising module asks your app for whitelist , your app is asking device manager to provide that info. That means that device manager will give the already bonded peers as whitelist. I think that is not what you intend. Instead of asking device manager, you need to construct your whitelist with the central address-

Also, i add options.ble_adv_whitelist_enabled = BLE_ADV_WHITELIST_ENABLED. in function advertising_init

case BLE_ADV_EVT_WHITELIST_REQUEST: { ble_gap_whitelist_t whitelist;

					ble_gap_addr_t    * sp_whitelist_addr[BLE_GAP_WHITELIST_ADDR_MAX_COUNT];
					ble_gap_irk_t     * sp_whitelist_irk[BLE_GAP_WHITELIST_IRK_MAX_COUNT];
					whitelist.addr_count = BLE_GAP_WHITELIST_ADDR_MAX_COUNT;
					whitelist.irk_count  = BLE_GAP_WHITELIST_IRK_MAX_COUNT;
					whitelist.pp_addrs   = sp_whitelist_addr;
					whitelist.pp_irks    = sp_whitelist_irk;

					err_code = dm_whitelist_create(&m_dm_app_id, &whitelist);
					APP_ERROR_CHECK(err_code);

					err_code = ble_advertising_whitelist_reply(&whitelist);
					APP_ERROR_CHECK(err_code);
					break;
			}

please post your code where the error is returned, please post enough code that we will be able to decode the problem

oh, it's white-list~ I use that thread and correctly with that sequence. But, a NRF_ERROR_INVALID_PARAM error with the call of func sd_ble_gap_adv_start. Also, i find that white-list is gotten from pstorage module. if i have an device address, how to create an white-list? Thanks~~~

Note that it's White-list (as opposed to Black-list) - not Write-list !

hi, dear aryan, I add that statement. But i find that statement doesn't run before i call sd_ble_gap_adv_start(&adv_params). I want start an advertising with writelist the first time i start advertsment but after unpair. Do they use the same way? Thank you very much~~~~

Please take a look at this thread

Updated

When you call ble_advertising_init function, you give an evt_handler function for this module. That event handle module will be called with event BLE_ADV_EVT_WHITELIST_REQUEST and BLE_ADV_EVT_PEER_ADDR_REQUEST when your application calls ble_advertising_start in which your application provides whitelist details. Look at the message sequence chart for this here Your advertisement mode cannot be directed or directed_slow because whitelist is not used for those types.
