Scanning for bluetooth devices
 

I am working on a project for college that involves bluetooth. I was required to use .Net. I have only programmed in C before, and therefore have started to teach myself C#. I have written all of the program already, including sending the data over a bluetooth connection. The only part I am having difficulty with is scanning for bluetooth devices in the area.

Can anyone give me any ideas on how to go about doing this or sample code.

Thanks a lot,
Tim

I haven't read through all the material, but it looks like it's specific for each blue tooth device. You'll need a BlueTooth SDK from the hardware vendor and then use PInvoke to access it's functions.

This newsgroup thread seems to be excellent.

This is absolutely not true! I haven't done bluetooth in C# before, but I've done it in C/C++ and am familiar with the bluetooth protocol. You need to just do a device inquiry over sdp (Service Discovery Protocol). This is not vendor specific---A Huge Nightmare if it was vendor specific!!! Look in your API for SDP I'm sure you'll find something. If you decided instead to run Linux and bluez then I could help you :).

Can you please share some of your code to how we able to read from the bluetooth device, and respond.

- Thanks.

Hi, maybe late, but here is a good place where you can find example code about how to perform SDP, with microsoft's bluetooth APIs:

About data transfer between devices, I'm still working on it. I'm new to visual C++ and MFC, so I'm finding a little bit difficult to achieve the goal of creating a piconet. I think now I am close to it, and if any one knows anything about the topic of bluetooth piconets, don´t hesitate contacting me.

Hi Tim,
I am not sure but maybe u could use OBEX to discover the Bluetooth devices around the area and connect to it?
By the way, I am interested in your application, care to talk/post your code?
I am doing a C# application to communciate between desktop and PDA.
I have problems converting the VB .NET application found at http://www.devx.com/wireless/Article/11511/0 to C# application.
Please assist
Thanks.

I am also involved in a project where I use a bluetooth usb dongle connected to the PC(which communicates with other bluetooth devices). So can I know " what would be the most suitable programming language in developing my own application programs for that USB bluetooth dongle?". Please help me with this.
