[2005] Bluetooth Connection

[iMPR3SSiON]

Hi there! I've just wondering, how to connect 2 or more PCs with Bluetooth?
I've read some threads about this, I figured, that Bluetooth is like a COM Port (representing COM Port) and all to do it is work with Serial Port tool in VS. But there are many questions. How to send and receive any data? What is OBEX (everything I know about OBEX, that is for file trasfering between mobile phone and PC)? Can you tell me, how to do something with BT? You know, send a data just, thank you so much!

Actually, there are a number of resources out there. Here are just a few I found with a down and dirty quick search.

There is something wrong. I wanted some code and maybe some instructions how to use Serial Port.
Some incredibly expensive add-ons is not especialy good a way to learn Bluetooth.
Please, can anybody send some code? Thanks

I guess it depends on your Bluetooth. Mine is an IOGear and I just added Serial ports to its configuration. After that I didn't worry about it being Bluetooth, it was just a serial device.

[iMPR3SSiON]

Thanks. Just some questions. Do I have still full BT speed? I mean something about 260 kb/s? When I send a file or something ... And, could you send there some code how to open serial port and receive some data? Thank you.

[dbasnett]

I have used BT serial and had about 1Mbps.

See my signature for my serial port stuff.

[iMPR3SSiON]

Cool! But I can't open your stuff, cos I have VS 2005. Is it works in 2005, or only in 2008?

Does it matter when I open port COM5 (for example) and user on other PC opens COM3 port?
Can we comunicate then?

[dbasnett]

Sorry, it is 2008.

You can use different ports on the PC's. I used Hyperterminal at one end when I was testing.

[iMPR3SSiON]

Nice! And ... I am sorry, but still a few questions are there.
How can I retrieve BT Device Name and Adress?
You know, I have some rubbish from Manufacturer, that normally works win my mobile phone etc., it retrieves adress (MAC Adress...??) and name ...
I hope you help me, I'll rate everything

[dbasnett]

Check Serial Port in my signature. Untested 2005 version.

Should not need it for serial port, but it would depend on Manufacturer.

I think you need to find out how to add a serial port device to the BlueTooth config.

[dbasnett]

I am pretty sick, so don't count on me being here much.

[iMPR3SSiON]

ok...

[iMPR3SSiON]

Actualy, I've been laborating with this Bluetooth Technology and I found, that it isn't so great. To communicate thru the COM port you must to set up BT drivers (set a COM connection with other PC). So question: How can I find a BT Devices in VB.NET? I already know how to communicate thru COM, but I can't find any device in range with my code. PLS Help

[iMPR3SSiON]

Anybody can help?

[dbasnett]

If there are not devices in range then what makes you think switching to direct driver interaction will help?

I've done smaller things with BT to connect with a robot. However, I was connecting at 9600, which is WAY slower than what you are talking about. My needs were also relatively trivial, as I never did need to discover devices via code. DBasnett has done more of the high speed stuff, and probably more BT stuff.

It may be that some of what will be necessary for you is manufacturer specific. There must be BT standards, but for the device I work with, I use the device software to discover other devices and connect to the remote (the robot in my case). However, if I don't do the connection part, it will still send the information, there is just a delay that is normally fatal to the operation prior to the send. I guess the serial port for the connection is fixed by the software, as well, now that I think about it.

Not very helpful I'm afraid. This is a topic that I have been meaning to look into further such that I can avoid the step where I actually connect the BT devices, but I haven't gotten to it, yet.

OT - Shaggy - Is NXT a good place to start with robots? A little pricey. I am so bored and idle, which causes me to dwell on things that there isn't any point in.

[Shaggy Hiker]

I haven't looked at NXT, but I certainly will. I'm stalled out for two reasons: 1) All my money is going into some yard work, 2) My $300 worth of sensors are producing so little useable data that my design is right down the chute. I need to find a sensor that will do the job, and that will take a bit of trial and error.

Oh yeah, take a look at RoboticsConnections. I really like their traxter base, and it looks like they have fairly good .NET software. The price may be a bit high, though.

[iMPR3SSiON]

Thank you, man
everything you sad was not very helpful, but I am persuaded about this question and I will mark this thread as RESOLVED, thank you so much
dbasnet also

[iMPR3SSiON]

Please, can you tell me this thing ...
I found that COM8 is BT Connection Port (with this port I am able to connect to "server", guy, who started connection (it usually takes longer time) ), but can I start multiconnection with this port? I mean, can I somebody connect to our started connection? Thanks.

[dbasnett]

i have a serial port link in my signature that has worked over BT serial ports.
