New Post: Windows 7 (BT 2.1 SSP Auth) - How to pair a Bluetooth Keyboard

sgurram — Wed, 22 Feb 2012 23:54:31 GMT

Hello,

I would like to pair Bluetooth Keyboard on a Windows 7 (BT 2.1 SSP Auth) tablet. The tablet has BT 2.1 SSP Authorization. I have instantiated the BluetoothWin32Authentication component and listening for the event for Legacy, JustWorksComparison, Numeric and PassKey type auth events.

Once I discover and select the keyboard, I am not sure how to send the pair request to the keyboard device. I think, I should use BluetoothSecurity.PairRequest method, but that method takes a pin. When I try "0000", the pair request is not success.

When I attempt to pair Bluetooth keyboard in Windows 7, it displays dialog with the PIN saying, I should enter the same PIN on the keyboard to successfully pair the keyboard.

I am not sure how to implement this using your API. Thanks a lot for your help.

I am trying to pro grammatically determine which com ports have been assigned to which Bluetooth devices. Any ideas how to accomplish this?

What code would be necessary to determine which virtual com port has been connected to a bluetooth device once the serial port service as been activated?

New Post: test Console app - widcomm BT stack

dglnz — Mon, 20 Feb 2012 09:48:11 GMT

Below is code I have cut and pasted to see if I can get a connection to the BT scanner I wish to capture scanned barcodes from.

I am now at a bit of a loss as to where to go/ what to do.

Also note the OBLEX lines are commented out due to them giving me errors otherwise I don't believe I need to use OBLEX but then I'm walking blind with BT at present.

My ultimate aim is to...

Have this program loop every N minutes or seconds looking for a connection (this I believe I can do with code I have here by including a sleep N statement.

Once a connection has been established to pass commands across to the scanner to draw down the data residing on the scanner.

I have got this exact program working against a USB version of this scanner - Opticon 2001and I am now wanting to access the Opticon 2002 version. I believe I', not too far away from success.

any help would be great, In the mean time I shall go a have a fiddle to see if I can get this to display some details (I see when I'm stepping through the details of Mfg name etc).

cheers

To let you know I got this solved - issue was due to the WIDCOMM.DLL.

I copied the 2 files under \Program Files\32feet.NET\Broadcom\Win32-x86\redist and placed them in the directory forSdpBrowserDesktop.

I was then able to successfully get barcodes numbers from the scanner when a barcode was scanned.

------ THIS CLOSED THIS ISSUE FROM MY PERSPECTIVE ------

thanks.

All the conversions seem fine with no error (all are either "no conversion required" or "successfully").

As to "master mode", is that the scanner mode? So the scanner should connect to the PC? Or is that the PC makes the Bluetooth (RFCOMM) connection to the scanner?

If the latter,then its simple to create a program to connect to the scanner. As a test you can use the SdpBrowser sample. Close any programs using the COM ports and run the sample, discover the device or do Discover->AddDeviceAddress. Then on the Client tab select the device and service "Serial Port" and try to connect. Simple code is as shown in the docs http://32feet.codeplex.com/wikipage?title=General%20Bluetooth%20Data%20Connections&referringTitle=Documentation e.g.

    BluetoothAddress addr
      = BluetoothAddress.Parse("001122334455"); // ... ... ...
    Guid serviceClass;
    serviceClass = BluetoothService.SerialPort;
    var ep = new BluetoothEndPoint(addr, serviceClass);
    var cli = new BluetoothClient();
    cli.Connect(ep);
    Stream peerStream = cli.GetStream();
    peerStream.Write/Read ...

New Post: SerialPort Write whilst Reading

alanjmcf — Thu, 16 Feb 2012 19:12:30 GMT

There shouldn't be any issue with simultaneous access to read and write.

Are there any other command you can send to the scanner? Do they work?

It *might* be that the StreamWriter is doing something to the 7 value. Try just a simple program that writes the single 7 byte to the Stream, without wrapping it in a StreamWriter. (I doubt this is the problem).

Is the protocol all line based perhaps? So do you need to send a NewLine (e.g. CRLF) to get the scanner to action each command?

What are the services/profiles? The Microsoft Bluetooth stack has no support for HSP/HFP 'headset' (only as 'audio gateway') for instance.
