Bluesmirf Roboduino recieves input but not moving still

[offy]

So I had my robot though the USB on roboduino so I could use W,A,S,D to move it. It worked out good. So I got my bluesmirf hooked up and now it gets signals but it doesn't do anything. I see the RX and TX led's light up, and nothing works. How does the bluesmirf recieve data? Does it take acsii to what it is or what? I have been having the worst time with this.

-Thanks in advance.

Three things you should check

1, Make sure you have RX and TX the right way around.
2, You are using the right baud rate ( I think the bluesmirf is default 9600, but can be changed).
3, Also you should to connect CTS and RTS together if you are not using them for handshaking of some sort.

Hope this helps

I have all of that. Does the bluesmirf take the input and process it to Hex or Acsii?

Connect RX and TX on the bluesmirf together and send "A" through hyperterminal and see what comes back

[offy]

Why would I connect them, it will not be able to connect or anything.

Also I don't use hyper terminal, I use gtkterm on ubuntu.

[Razor Concepts]

It will be able to connect, it is just connecting with itself. If you connect RX and TX on the bluesmirf, if you send 'A' the bluesmirf will send it out and receive it, so on your computer it will show up as 'A'.

Did you read the UART and bluetooth tutorials? It's all in there.

[offy]

I read some of it. I will try the rx to tx right now. I will update in a few.

Nothing shows up.

[SmAsH]

then the bluesmirf is probably gone.

[offy]

Damn not again. I hate sending it back to robotshop, it takes them so long.

[Qubix]

I'd try the same test (connecting tx and rx) at different common baud rates (4800,9600, etc, just to make sure. Like Razor Concepts said , you really should get back what you sent out in your terminal program.

Since the RX and TX leds are lighting up it would seem like something is passing through it.

[Qubix]

I read the datasheet (for the newest module) it says 115,200 is the default baud . You are using 9600 in your code.  Could be your problem
