Does bluetooth smart module connect another bluetooth smart module ?

I can get an information that bluetooth smart connects bluetooth smart ready. But I can't get an information that bluetooth smart connect bluetooth smart ready. So, Would you teach me about the above question? In addition, I would like to know that how much BLE module that nRF 51822 is build into is. I kindly ask for your cooperation.

"Bluetooth Smart Ready" means devices that support the classic Bluetooth (BR/EDR) in addition to BLE (Low Energy). These are dual-mode devices. "Bluetooth Smart" means BLE only.

"Smart Ready" can therefore connect to any bluetooth device. "Smart" can only connect to other "Smart" or "Smart Ready" devices. The nRF51822 softdevices are only BLE, so you can connect to any device with "Smart" in it, but not any classical Bluetooth devices running over BR/EDR.
