case BLE_ADV_EVT_WHITELIST_REQUEST:
     BLE_LOG_DEBUG("%s:BLE_ADV_EVT_WHITELIST_REQUEST.", (uint32_t)__func__);
     uint32_t err_code;
     const ble_gap_addr_t whitelist_addr = {1,2,{0x7B,0x1C,0x5B,0x47,0x5D,0x20}};//vivo
     const ble_gap_addr_t      *p_whitelist_addr[] = {&whitelist_addr};
     ble_gap_irk_t  whitelist_irks[BLE_GAP_WHITELIST_ADDR_MAX_COUNT];
     err_code = sd_ble_gap_whitelist_set(p_whitelist_addr, 1);
     if (err_code == NRF_SUCCESS)
	 {
		 BLE_LOG_DEBUG("after set BLE whitelist.");
	 } 
	 // White list reply
	err_code = ble_advertising_whitelist_reply(&m_advertising,&whitelist_addr, 1, NULL, 0);
	if (err_code == NRF_SUCCESS)

Hi,

Can you try what is suggested in this thread?

[guofengying]

thank you for your reply, i will try your suggected. i just want hard code whitelist,just accepted the connection from the whitelist device, i wonder why this guy didn't encounter fatal
error when he set the type to 2 ( BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE).this

hi mttrunh ,

i have already read your suggest thread carefully, but i found we have different purpose.can we add the the  device  with privete resolvable bluethooth mac into the whitelist by using the function sd_ble_gap_whitelist_set? if we can, why i encounter the fatal error,please in try my code in the ble_add_his_keyboard example. thank in advance.

Hi,

The ble_gap_addr_t whitelist_addr can't contain BLE address of type BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE. You need to add the IRK to the whitelist, this will whitelist a device with the random private resolvable address type. You need to bond to get the IRK.
