What does sd_ble_gap_sec_params_reply() return?

Hi, Martin:

I modify as below:

keys_exchanged.keys_central.p_enc_key  = &central_peer_enc_key;
keys_exchanged.keys_central.p_id_key   = &m_peer_table[m_connection_table[index].bonded_dev_id].peer_id; 
keys_exchanged.keys_central.p_sign_key = NULL;
keys_exchanged.keys_periph.p_enc_key   = &m_bond_table[index].peer_enc_key;
keys_exchanged.keys_periph.p_id_key    = NULL;
keys_exchanged.keys_periph.p_sign_key  = NULL;

err_code = sd_ble_gap_sec_params_reply(p_ble_evt->evt.gap_evt.conn_handle,
                                       BLE_GAP_SEC_STATUS_SUCCESS,
                                       &m_application_table[0].sec_param, 
                                       &keys_exchanged);

if (err_code != NRF_SUCCESS)
{
    DM_LOG("[DM]: Security parameter reply request failed, reason 0x%08X.\r\n", err_code);
    event_result = err_code;
    notify_app   = false;
}

But after bonding successfully several times, it still return Confirm Value Failed error.  Please check the Sniffer data:
