NPM code to differentiate USB and bluetooth serial port

0.00/5 (No votes)

See more:

In my project I use Bluetooth and USB scanner to integrate with my app. So I use NodeJs to connect the scanner's serial port.

There may be a conflict when both Bluetooth and USB scanner gets connected at the same time. So what I need is how can I differentiate serial port whether its a Bluetooth or USB.

What I have tried:

I have tried to connect both the scanner separately. Now I have to do this. Please provide some code snippets or some useful links which may solve my problem.

Is the scanner connected to the server, or is this not a web application?

Yes this is not a web application. We are trying to write a NodeJs service to communicate with the scanner. Its basically an UWP app.
