Third Party Bluetooth Serial Interface

Hi,

I have a third party EEG headbox with bluetooth connectivity using serial interface. I did the followings:

1. From Bluetooth, added the device that was successful. Furhtermore, two unidirectional ports were added to the device i.e. COM3 (incoming) and CoM4 (outgoing) - VISA
2. The device is successfully accepting the commands i sent with a beep acknowledgement.

The followings are the issues.

1. The device is not responsing with any data i.e. nothing coming to pc/ laptop because of the device is using two unidicrectional COMs.

Query:

How can i assign the one COM to the device so that i can receive the bytes as well.

Regards,

Abdul
