Crazy question. I fear that I know the answer already.

I ordered the Bluetooth Modem BlueSMiRF Silver bluetooth rather than
the Bluetooth Mate Silver. Is there any chance that I'll be able to
get this to work? I'm a little wet behind the ears when it comes to
bluetooth.

This is what I ordered.

FWIW I bought this for $20

Plug and play. Still havent figured out how to change baud but for the
price and my needs....

Got mine working last night (BlueSmirf silver). You must change the baud rate to 57600 as the default does not work.

Thanks for the reply, Ross.

Exactly how are you changing the baud rate? I'm having a hard time
doing it. Do you have a link to instructions? I'm running Vista and
Win 7 (different computers).

Rolf,

Have you viewed the datasheet on the board for the commands to change the baud rate?

Looks like you need to send the command AT+BAUD7.

If only I had read this before I bought mine.

Rolf,

What methods have you tried yet? Are you on a Mac or a PC? What version OS are you using?

Kubuntu. I can open a connection to the uart with minicom. I do not get
any OK's back

Sorry for the late reply, I used windows 7 with roving networks terminal emulator (can't remember the name right now). Steps based on memory without the data sheet or computer in front of me (phone) so ...

1. Pair the smirf with computer
2. Power cycle smirf (have to send  the command code within 60 seconds of powering up)
3. Connect to smirf using terminal, baud rate doesnt matter.
4. Send $$$ enter, should see CMD bounced back
5. Send D enter to verify connected, should send back  info about dongle, including the current baud rate
6. Send SU,57 enter, should get AOK back, this sets the rate to 57600
7. power cycle, enter command mode and send D to verify baud was changed and saved.

Sorry I have been working through a backlog of emails after being sick.

Thanks for the reply, Ross.

I just want to confirm that you're using the modem that I linked to
rather than the other bluesmirf silver bluetooth device that sparkfun
sells.

I will try this when I get home tonight.

Pretty sure it was that exact modem, bought it two weeks ago.

That is music to my ears.  I'll update tonight if/when I get amarino talking to it successfully.

Yeah, I purchased the Smirf specifically to interface with amarino and chose the silver because It was cheaper and I didn't need the range of the Gold. If you are using the sensor graph tutorial remember to change the MAC address in the java code to match your device. I got the sensor graph working with an analog IR distance sensor as input within minutes of solving my baud rate issue.

Good luck.

Sorry for the lack-o-updates.  Been hell week so far.

I was unable to get the buad rate changed.  I am able to use putty to get to the device over COM7 on my laptop, I see that it's paired, and when I select "D" I get the device information.  I see that it says brate = 115K passcode=1234 and other stuff.  

When I tried your method to change the baud rate it came back with an error.  I only had about an hour to mess with it the other day, but tonight I will try some other methods to change it and see if they work.  

Thanks for asking.

Steve,

Understand about the crazy week :) I am just getting home from school! Hope this helps, if you want to contact me via google chat that would be fine with me.

On page 11 at the top you will see the SU,<rate> command, thats what you need to use, try other baud rates just to see if the command works?

SUCCESS!!!!

I'm not sure what it was that I was doing wrong but this time it went
smoothly. I ran putty, setup a serial connection to COM7, echo on.
Once paired sent "$$$" got "cmd" back. Then sent "d" and got the
information on the device. Sent "su,57" got AOK. Restarted the
device and send "d" and got the correct data back. Now the Test
sketch blinks the LED.

Thanks for your help, Ross.

Hopefully I can reciprocate the help to you or others in the group.
