    Hi,

    First of all thank you for this package, it is working great so far!

    I'm wondering if there is an easy way to create multiple ros connections to publish to/subscribe from different IP addresses. Basically I would like to send & receive data from 2 vehicles to 2 different tcp endpoints.

    Regards

    Unfortunately, multiple connections don't work well with the currently released code, sorry.

    Is this probably the reason I am encountering the performance problems (see the other thread in this forum)?

    Hmm, well, possibly. Long story short, there are some static variables (like "has connection error") that end up being shared between the connections, causing them to interfere with each other. I wouldn't have expected it to manifest as a performance problem though.
