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

Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
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)
Cons:
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.
Other:
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
Bottomline:
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!
