I'm looking for a way to determine if a COM is a standard COM or if it's an SPP COM, also known as a cable replacement bluetooth adapter for a COM device.
I have a device which works both in USB (COM -> USB) and Bluetooth, and the Bluetooth interface works with SPP.
I am currently using System.IO.Ports.SerialPort.GetPortNames() to get the COMs.
Is there a way to determine whether or not it's a connected with Bluetooth or USB?
SOLUTION:
System.Management.ManagementObjectSearcher Searcher = new System.Management.ManagementObjectSearcher("Select * from WIN32_SerialPort");
foreach (System.Management.ManagementObject Port in Searcher.Get())
{
foreach (System.Management.PropertyData Property in Port.Properties)
{
Console.WriteLine(Property.Name + " " + (Property.Value == null ? null : Property.Value.ToString()));
}
}
And the output is something similar:
