How to identify which COM ports are connected to BlueTooth devices?
I'm wondering if there is a way to know, using a C# program, among my COM ports which are connected to BlueTooth devices?
For example, let us assume that of my ports 1 through 9, the COM ports 7 and 8 are connected to some type of BlueTooth device. So I want my C# program to scan all my COM ports, and indicate to me that ports 7 and 8 are connected to BlueTooth devices.
How can I achieve this goal? Specially code samples would be highly appreciated.
Thank you in advance!

Re: How to identify which COM ports are connected to BlueTooth devices?
If you are able to program the bluetooth device, then you need to write a function which recieves a ping query from your PC and send the answer to it.
You get the ports on your computer and then sends query to each port (preferrably keyed one) and the port which sends you the correct answer is conencted with a BT device.
If you are not in condition to program the device, then just read the specification of the BT-stack. There must be some function in the API for handshake.
