I too faced this problem. This worked for me: First list all the wireless devices using rfkill list command.

Then use the command rfkill unblock <index> where index is the number of the bluetooth interface.

Eg: My rfkill list outputs:

0: sony-wifi: Wireless LAN Soft blocked: no Hard blocked: no 1: sony-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no 3: hci0: Bluetooth Soft blocked: no Hard blocked: no

So I run rfkill unblock 1 and rfkill unblock 3. Hope this helps.
