I'm trying to made a connection with a device that change the relay state. The device talk via UDP (port 2424) and if I try to read the status with "Wait for response from server" checked I'll see the correct response returnd, but if I add every compoent that follow the Socket client the VAD goes in error with error.badfetch. There is some trick about the UDP connection that I don't know? Second thing: the device accept ascii charcter incluse the null (ex. to swith off the realy the string shoud be 'A\0B\0C\0 where \0 is the null character) but if I'll check with WireShark the string sent I notice that only the first charactar ('A') is sent. There is a way to manibulate or send ascii code without using external program\function?
