How can i start an advertising with a whitelist?

[king]

Hi all, I'm reading the ble_peripheral samples of the SDK. I know start a advertising with the function ble_advertising_start(); Now, i know a central address, then i want connect to that device. I want start the advertising with a whitelist for can be connected by that central only. How to modify the sample codes and do i need irks or something else? Thanks~~

Please take a look at this thread

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.

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~~~~

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

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~~~
