Unnecessary connection

[GEO]

Hello, I have question. I using examples with nRF51-ble-peripheral-bond-handling with bls_service (PCA10028) and i have problem with unnecessary connection. I want that my unbonded (Android, iOs) devices didn't have a connection with PCA10028. When i use nRF Master Control panel i click on my connection (button "CONNECT) after this i I stay in screen with service and characteristic information on long time (did't go to my write characteristic or other) but my unbonded device holds the connect (of course it didn't have access to characteristic - i closed access) but it holds the current connection and other bonded device - necessary device can not connect to my PCA10028, why is occur, and haw can i forbid the connection no bonded devices? Thank you.

I deleted all bonded information on my PCA10028 and on the Android phone, then i download and program my PCA10028 proximity example, then go to nRF control panel, finde nordic proximity conection click on and... it connected without bond and will can stand still in this state long time (importent "without bond procedure" and with whitelist implementaition in this example). I didn't whant that unnecessary devices connect and do busy my PCA10028 long time... For examle.... I develope application which open my home door throw the phone (PCA10028 is peripheral, pone - central) i bonded my phone and PCA10028 and it workin good, i open close door as i whant.... but other gay take other phone, open the nRF control panel find my connection "open door" and connect it ...of course hi cann't open dore beacose it should go throw the security procedure, but hi can state in connection state (LED1 turn on) long time, then i comeback after job to home and cannot finde the "open_door" connection beacase it still busy by other phone ...this is problem...
