Good module, but no documentation – Wireless Bluetooth RS232 TTL Transceiver Module Reviews

Its a great little module. It`s not difficult to use and does not require external components of any kind to use with TTL level. It can handle TTL serial with no problem.
(ATTENTION: to connect to PC, you will need a level converter)
It has NO documentation whatsoever, so you have to browse around for some. The diagrams shown here from other users is OK, but the module can do so much more I regret it has no documentation with it. A site would do just fine.
IT SHOULD have a DIP package option for the amateur user. The pads are really small and one should use paste solder to have a good job done.
OK, here are some things one should know to use it.
You can connect it to your PC serial port to reconfigure it. Commands are high caption.
The original configuration is: Baud=9600; 8bit data; no parity.
To test connection, send AT - responds OK
To change pw: AT+PINxxxx - xxxx = pw
To change name: AT+NAMEnameinsmallcaps
To change Baud: AT+BAUDx - x from "1"=2400 to "8"=115200
BUY IT! I`ll buy one or two more.
As you can see, it`s a very easy way of adding a BT device for your project. I have testes with my PC and with PIC micro-controllers and it just works like a charm!
I hope the information posted can help you use it better!
