Please help. I can't connect my Nokia Lumia 521 to my Motorola EQ5 bluetooth speaker. When I try to pair it, it asks for the code. I put in "0000" as the instruction says but after a few seconds it says: "can't connect". The Nokia Lumia 521 will connect to another Bluetooth device, though (under the cabinet radio). And the Mototorola EQ5 will connect to my I-Pad.
