This Bluetooth module is manufactured by wavesen in China. You can download a copy of their Chinese or English documentation here: http://www.wavesen.com/download.asp The latest JY-MCU V1.02pro (HC-06) version of firmware is LinvorV1.8, which can be configured into either Master or Slave mode. (Older version can't!) AT+VERSION LinvorV1.8 Read the Chinese version of HC-06 documentation, which is different from most of the English versions online. The commands have a slightly different syntax: AT+ROLE=M (for master mode) AT+ROLE=S (for slave mode) The Master and Slave must use the same PIN number. The default is 1234. If you change the PIN numbers, you must discharge the radios for 30 seconds for the new PIN number to take effect. Configure correctly; this radio works perfectly! The Master will pair with the first Slave with the same PIN number. Once paired, the Master remembers the Slave and will pair automatically. HC-06 is simpler to use and configure than HC-05.
I used this to connect to an Arduino Micro board. Works perfectly! Note you may need to switch the BAUD rate there are tutorials online and in the end, I used the Arduino IDE software to update the board. Also, just-in-case when connecting to your phone or computer it will ask for a PIN the default PIN is 1234 unless you change it via the Arduino IDE software. For the Arduino novice, when connecting to your Arduino board the TX from the Arduino connects to the RX of the Bluetooth board and the RX from the Arduino connects to the TX of the bluetooth
