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?

It would also be a good idea to ensure you post in the right forum.

You need to be sure you are in AT mode before you send AT commands. Check LED.  Bluetooth should respond with "OK".

IF you get an OK in response to AT test but not to the necessary commands, you MAY have to set pin34 high on bluetooth. I understand not all commands can be set when using the standard push-button method, but I rather doubt the problem lies there..

I will post there.

Yes, 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.
