MITM Bonding issue with Android L

Now

Hi, we'd like to use nexus 7 II(android 5.1.1) to connect nrf51822, but cannot connect if nrf51822 uses whitelist.

step 1. we send advertising packets without using whitelist, and uses MITM. Nexus 7 II can do the bonding.

adv_params.type        = BLE_GAP_ADV_TYPE_ADV_IND;
adv_params.p_peer_addr = NULL;
adv_params.fp          = BLE_GAP_ADV_FP_ANY;
adv_params.interval    = APP_ADV_INTERVAL;
adv_params.timeout     = APP_ADV_TIMEOUT_IN_SECONDS;

step 2. then we send advertising packets with whitelist info, nexus 7 II cannot connect to us, even we did bonding before.

adv_params.type        = BLE_GAP_ADV_TYPE_ADV_IND;
    adv_params.fp          = BLE_GAP_ADV_FP_FILTER_BOTH;
    adv_params.p_whitelist = &whitelist;
    advertising_init(BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED);

But iPhone5s is okay on step2.

Is it google's issue? or we can do something for it?

-Thanks, Bill
