Hi Mitja_G.,
You are right, there is no current support of WSN in LabVIEW 2014 nor LV 2014 SP1.
There are some plans to release in the future tbut there is no official release date.
My suggestion will be to contact NI Branch in your country and discuss what are the options.
Knowing more about the opportunity and your hardware configuration, it will help finding the best solution for you.
If you need contacts of your local NI Branch, please tell me your country and I can send you exact e-mail address and phone number.
Best regards,
IR
