These are dual-mode devices. &quot;Bluetooth Smart&quot; means BLE only.</p> <p>&quot;Smart Ready&quot; can therefore connect to any bluetooth device. &quot;Smart&quot; can only connect to other &quot;Smart&quot; or &quot;Smart Ready&quot; devices. The nRF51822 softdevices are only BLE, so you can connect to any device with &quot;Smart&quot; in it, but not any classical Bluetooth devices running over BR/EDR.</p><div style="clear:both;"></div>
