no serial port over bluetooth

Hi, I am new to this forum and I have a question when using bluetooth to connect an external device (Blueport XP). This external device requires a serial port for communication, but I don't see the bluetooth on my laptop had assigned a port.

I would like my bluetooth to work as the following mode:


When I search online, I find other people who faced my case have difference hardware (Left is others, right is mine):


They have the "Standard Serial over Bluetooth Link (COMXX)" under the Port catergory, while my "Device manager" don't have a such a Port category.

I think that is the reason when my external device can be successfully connected (using passcode), but still not assigned the com port and thus no later communication.



I have checked my laptop configuration, my bluetooth is : Intel 7265 AC/B/G/N Dual Band Wireless + Bluetooth Version 4.0

So my question is: Does my bluetooth not support serial port profile (SPP)?
If it does support SPP, how can I make it work?

Thank you,
