Bluetooth module HC-06
If you want to rename the device, change it''''''''''''''''s name of the baud rate, you need to connect it tu the USB2Serial adapter and use a terminel (e.g. the Arduino IDE) to runn the following AT commands on it. The standard baud rate is 9600.
Pay attention to the fact, that the USB2Serial adapter only can do up to 230400 baud. I tried to set the rate to 921600 and did not get any access to the HC-06 either via the Arduino IDE nor via any other Terminal emulator. In that case, the easiers way is to write a little Arduino script that executes the AT commands right on the serial interface. Nevertheless you need to add a delay of a least a second after each command and the read the response. The HC-06 only executes it after around a second. Also notice that there must not be any or character added, so just use a simple "Serial.print(...)" command.
