Yes, but do you need to see that?

I'm assuming you are using iOS as a central, and the nRF51 as a peripheral.

I'm not sure I quite understand what you want to test, but as user9384 said, the access address will be used when in a connection, and this will not change throughout the connection.

The device address of the iOS device will change every 15 minutes. You can observe this by using the Sniffer. Just examine two connection requests that are 15 minutes apart.

Thanks for your quick response. When not connecting iOS with nRF51, iOS probably change own bluetooth address every 15 minutes. But once connecting between iOS and nRF51, never be changed during lifetime connection. So we cannot see when iOS automatically change own address, right ?

When connecting, the iOS device and the nRF51 use the device address (which is what changes every 15 minutes). Once in a connection, the link layer Access Address is used, and that address does not change for the lifetime of this particular connection. After the connection is established, your nRF51 application should not be affected by the iOS device changing device address.
