bluetooth attempt

I have been trying to get the Bluetooth System to work but the pin out does not work. First I realized that the vcc Pin on the motherboard side refers to +5 from the USB cable therefore it is not powered. Also shold the tx and rx be swapped?

First, my appologies for not getting back to this sooner. I have been really busy and forgot about this post.

Yes Vcc is 5V+. I have not tested this configuration so i am not sure it works, but if the motherboard requires an input of 5V+ on this line then this wont work. I understood that once the motherboard is powered and turned on the 5V line is hot and should be able to power the Bluetooth module.

TX and RX should always cross. TX-Transmit should connect to RX-Recieve and RX should plug into TX.

the vcc line is not powered from the motherboard. it is powered from the usb/computer. could 5v be pulled fom soewhere else on the motherboard?

I finally got this to work myself today.

I'm using the (Bluetooth Mate) from Sparkfun rather than the BlueSmirf, the only difference seems to be the pinout has been changed to match FTDI adapters, so its already a match for the Cupcake.

I made up an adapter so that the card was vertical rather that standing out where it could get damaged. I soldered a couple of wires from the adapter to the Vcc and Gnd pins of the I2C headers for power.

The final thing is that you have to change the baud rate of the Bluetooth adapter to match the CupCake, in my case that is 38600, I would assume they are all the same but you never know. Once I changed that everything worked.

Good luck.

It'd be great to see everyone's notes on how to make it all work, pics, and examples dropped in here: http://wiki.makerbot.com/bluetooth

I just posted a pretty detailed article on how to get your CupCake talking via Bluetooth. I posted it on the page you created. Hopefully this will help people out. :)

Has anyone gotten this working in windows? both tutorials I've seen use the "screen" command in OSX which I can't really find an equivalent for in windows.

Yeah, check out the tutorial at http://wiki.makerbot.com/bluetooth. It shows how to get it working on Windows.
