UDP - First access for input


I have a kmtronic and I am sending and receiving information using UDP commands.

To know the state of the ports of the Kmtronic I am using the following configuration (.items):

String KmT_in " " {udp="<[‘FF0000’]"}

This should return anything like “000000”, but only return… well, nothing

Then I change to: String KmT_in " " {udp=">[‘FF0000’]"}

and start return “FF0000”

Then I changed to it’s initial value: String KmT_in " " {udp="<[‘FF0000’]"}

And it starts to work fine.

If you restart the openhab, it all starts again in the same way.

Only works if you repeat these steps

Any clue?
