I have to look, since my project is very large and I really want to stay with jRDC2, I would have to go away now from jRDC2, then it throws me back a few months.
I have tested a little and if I stop the time and send a message via button, this takes between 400-600 milliseconds. (on my home PC with a 8K internet connection) For this reason, I will program a service that can handle this (without starting a script), with your tips, I now know how to start. Thanks
