serialPort_nws_yarp doesn't seem to work ok for face expressions

[pattacini]

Describe the bug
Following up on robotology/icub-tech-support#1539, we replaced the deprecated device serial (which has been removed in yarp-3.8) with the latest one serialPort_nws_yarp.

However, we didn't manage to make the face expressions work on iCubGenova11.

To Reproduce
Steps to reproduce the behavior:

We launched it this way:

yarpdev --name /icub/face/raw --device serialPort_nws_yarp --subdevice serialport --context faceExpressions --from serialport.ini

Is that correct?

Expected behavior
A clear and concise description of what you expected to happen.

To be able to control the face expressions normally.

Screenshots
If applicable, add screenshots to help explain your problem.

Configuration (please complete the following information):

• OS:
• yarp version: yarp-3.8 out of distro 2023.02.3.
• compiler:

Additional context
Hi @randaz81

Did you make some tests with serialPort_nws_yarp paired with faceExpressions?

That specific nws needs to be launched through yarprobotinterface because yarpdev does not perform the attach operation on that specific device.
