What ports have you tried? Most likely the right one is GT06.

@tananaev thanks for answer! i've tryed 5013-5002-5013 and nothing, wich port is that'?

@antontananaev you were wrigth, it was the gt06 protol thank you very much! you are the best!!!!

Why didn't you try all the port here first?

@antontananaev i'll tried all ports, but without results, when you guide me to the gt06, went to the forum and i have to modify the config file, then put the correct port and the device was online
