Thank you for your answer. I have a filter in the adv report that requires the adv response, then it makes some confuse for me. Now I understand it.

You can find the definition of active field in ble_gap.h:

uint8_t  active         : 1;  /**< If 1, perform active scanning (scan requests). */

Active scanning means that the scanner send a scan request after it receives the advertising packet. The advertiser will send a scan response with additional data after that. (the second adv data packet you set up when you setup advertising data)

I don't see any relation between active scanning and whitelisting or connection establishing here.

Hi Hung Bui, I found the reason that have to set the m_scan_param.active = 1. But I don't understand clearly this parameter. I see in the hrs example, it's set to zero that works normally. Can you explain for me?

Thanks for your support. After reset, the erase_bond flag is not set when the device is booting. But I check the irk_count = 0 and addr_count = 1 when starting advertising

Hi Hải,

In you test, have you reset the peripheral/central board after bonding ? You may want to check if the erase_bond flag is set or not when the device is booting.

You meant there is no bonding information on the peripheral, then whitelist shouldn't take any effect. Could you check the irk_count and addr_count inside m_whitelist when starting advertising ?
