You're not sending 5 bytes. You're sending 5 integers converted to a string. That string is much longer.


We can't say much else about it, as you've given us just a small peace of the puzzle.


Post the code. Also the receiver end.


Why a while loop polling the Stop button if you already have an event structure? Add a Stop value change event, and put the integers and the conversion there...

Hi saikranbusharaju,


how can i reslove my problem,

Don't place that VISARead function inside a case structure inside an event structure to have it called continuously…


Btw. when is your event called? "READ" seems to be an indicator and no control usable by your users.


im placeing my VI please go through it,

No, you just attached an image. There is no VI available to us…

Did you note wiebe's request in message #2? Please post the code!

You've put typical event stuff outside the event structure, and typical non-event structure things in the event structure.


I'm actually not sure how you get this to do anything useful at all...


Perhaps someone else has something meaningful to say, but most advice will come down to "do some courses" or "here's my completely different solution for you".
