You should set the address and add_cnt after you call pm_whitelist_get()

yes, I add the address to p_whitelist_addrs directly .But after the call pm_whitelist_get() ,I find add_cnt =0.

Do you do bonding with the peer device ? If you do, then the peer should be added automatically to the peer list.

What you can do, if you don't do bonding, is to add the address to p_whitelist_addrs directly . You can find where to add it in scan_start() , just add your extra address after the call pm_whitelist_get() and increase add_cnt.

In addition, like you said, I sets the whitelist in whitelist_load().From ble_app_hrs_c,What should I do in scan_start()? This defines ble_gap_addr_t whitelist_addrs[8];.So, I don't know how to deal with whitelist. Is it add pm_peer_id_t peers[8] or ble_gap_addr_t whitelist_addrs[8]? thanks!

Thank you for your answer. What you said is correct, but I don't konw how to add a suitable whitelist format in (whitelist_load()). This is defined in this function pm_peer_id_t peers[8]; ,I want to add a MAC adress {0xF5,0X51,0x43,0x5D,0x41,0x43}.I guess add the MAC adress in peers, Is that right?Thanks again！

Hi,

I recommend looking at the BLE Heart Rate Collector Example (ble_app_hrs_c), which uses peer manager and whitelists for a central. It sets the whitelist from whitelist_load(), and uses a function peer_list_get() to build the list of (bonded) peers.

To directly connect to a whitelisted device, use sd_ble_gap_connect() with use_whitelist set in ble_gap_scan_params_t. You can also set use_whitelist in the scan parameters for sd_ble_gap_scan_start(), which will generate BLE_GAP_EVT_ADV_REPORT events only for advertisements from whitelisted devices.
