Bluetooth Newbie Getting started? - Electronic Circuits Projects Diagrams Free

Hi

I have just baught a Bluetooth module from SparkFun:
The BlueDongle:
http://www.sparkfun.com/commerce/pro...roducts_id=642and
The BlueSMiRF
http://www.sparkfun.com/commerce/pro...roducts_id=158

I have connected the BlueDongle to the PC and am using Hyperterminal to communicate with it. Upon sending "AT" to the device it returns OK
So I am assuming that it works fine.

I am interfacing the BlueSMiRF with a PIC (16F873) and am using printf
in PICC to send data to the device (Pin C6 on PIC to Rx on the BlueSMiRF). This is where the trouble starts.
I do not get any transmission (ie I see nothing on the Hyperterminal screen); I dont even know if I am getting anything sent.

Can someone please help me to get started on solving this problem?

Thank you in advance
a.

were you able to successfully associate the smirf with your PC? There is some sort of handshaking process you must go through, to add a "new device".

Hi JustDIY

I have not got the BlueDongle to work. In fact when I wrote that
The BlueDongle responds to "AT<cr>"
it was the modem on my laptop.

Now it appears that I cant get the BlueDongle to talk ot Hyperterminal. I cant type anything into the Hyperterminal window!

Can you please suggest something that can get me started?

Thank you
a.

following these instructions, how far do you get before things go wrong?

maybe your computer doesn't support the bluetooth dongle?
