JY-MCU Arduino Bluetooth Wireless Serial Port Module
VCC 3.6V - 6V
- To initlalize the BT module, send it the following AT commands: AT+PIN1234 <cr> AT+NAMEdongle <cr> AT+BAUD4 <cr>. The last command will set the baud rate to 9600.
- Then on the PC, connect to a new Bluetooth device, use the same PIN number as above, make note of which serial (COM) port it maps to and then use Putty (Windows) or screen (Linux) to test!
