  • Good module, but no documentation

    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.

    OtherThoughts:

    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!
