    Hi,
    UDP communication with raspberry pi2 work fine, but I need to count byte in input. There is szCount variable, but it remain to zero.
    Can I do something?

    Hi,
    could you give this a try and
    and you need to wait till xReady = TRUE, after that data's are valid and szCount should be <> 0.

    Hi,

    if you Change FB_UDP_RECEIVE.xDone to FB_UDP_RECEIVE.xReady in Network 4 it should work
