	~~== Introduction ==~~
	* This module uses the master Beken (Broadcom) is BK8000L chip module provides high-quality sound and compatibility, overall better performance.
	* Bluetooth module uses driver-free way, customers just need to block access to applications, you can quickly and easily implement wireless transmission of music, enjoy wireless music fun.
	* SPP supports data transmission, while supporting the key and AT serial command control, SPP and audio can be performed simultaneously.
	* Can store six paired devices, the module is automatically switched back even to the last paired device. If six paired devices simultaneously open, then automatically connect to the last paired device.

== SPP Commands (e.g. change password, send data) ==
Note:
# Make sure module paied with your device (phone)
# Use BlueSPP app from Google play, make sure BlueSPP is connected
# Run following commands.
Commands:
* APT + SPPXXXX four-digit password (8888),
Open SPP by using password
e.g. APT + SPPXXXX \r\n as long as the hair once,
The password is correct: OK \r\n
Password Error: ERR \r\n
* APT + XXXXXXX total data length of each time send/receive, it recommended not to exceed 64byte
e.g. APT + XXXXXX \r\n
The data sent to the mobile phone side
Success: OK \r\n
Error: ERR \r\n
* APR + XXXXXXX total data length of each time send/receive, it recommended not to exceed 64byte
e.g. APR + XXXXXX \r\n
Data received from the mobile terminal
Data sent over the phone
APR + XXXXXX \r\n
