This module gives the Arduino board the possibility to communicate with the computer, laptop or even telephone via Bluetooth. The HC-05 module is already attached to the baseplate in this version, so that it can easily be connected to the Arduino.
Very satisfied, they work fine and also delivered quickly

Ordered 5 or 6 pieces, but the majority of these give the response to AT + VERION? => '' VERSION: 3.0-20170601 ''. Little documentation can be found on this, cooperation with the previously ordered versions (2.0) appears to be unreliable (often the data transfer is incomplete) and although AT + ROLE = 1 works correctly, inquiring to bluetooth devices is not possible. Unfortunately I had arranged this mutually, but my order number is missing. Nevertheless, the order may be received quickly!
