Setup cheap bluetooth module
Hey!
I resently bought this bluetooth module http://cgi.ebay.com/Bluetooth-UART-RS232-serial-Converter-Module-TTL-Ship-/20051...
But i cant seem to configure it via putty or other software... I have tried all sorts of thing but notthing works. Right now i have hooked it up like this... expect for the blue wire, cant see the point with it.. I found the image the this topic http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1272527812
I have also set the pio11 as "high" as described in the datasheet to enter "AT command response" http://www.sendspace.com/file/yyu4vy
My problem is that i cant get any response from the bluetooth module, in putty it seems to be connected, but i cant type anything i putty. The cursor is just a green square... The only "response" i can see is when i press "enter" then the RX led on my seeeduino i lighting up...
Hope anyone can help me...

You guys ever try these
You guys ever try these modules:
http://www.ebay.com/itm/Arduino-Bluetooth-Module-Slave-Wireless-Serial-Board-X3-/330592919930?pt=LH_DefaultDomain_0&hash=item4cf8dfa17a
You can get them from many places on ebay for around $10-12 with shipping, if you order 3 at a time it's easy to get them for $10 each. I'm not a bluetooth expert, but they seem to work for me. I've never done anything high speed with them, and i've never done a range test, but i've never had a communication error. I've linked my Android Asus Transformer tablet with them, and my cell phone, and they connect up. I used em with a grblshield, it's a cnc controller, to wireless control some stepper motors.
seeedstudio sells very similar looking modules for $20, they almost look identical.

New module
I gave up this module!
So now i bought the RN-42 module, hope this work better! Do anyone know where to find some good tutorials for this module and my arduino?

Tutorials on Sparkfun perhaps
Sparkfun uses the RN-41 module (pin compatible with RN-42) on the Bluesmirf they sell. There is probably some tutorial and forum posts on using it with an arduino on their site.

It's a pretty simple serial
It's a pretty simple serial device so most any tutorial on Serial com will work with it. You just need to make sure you bind it to another bt device(bt usb key on a computer) to use it.
