bluetooth hc-05 slave-loop

I put bluetooth on AT + ROLE = 2 now does not go out, even in configuration mode, if I put AT answers AT and not OK. How do I get out?

I set the EN pin to high logical level, the LED flashes very slow, but if I send AT it responds AT.

Before putting in SLAVE-LOOP with the command AT + ROLE = 2 he answered OK
