tcp - bytes to read

[heelklick]

Hi,

I have a TCP connection between 2 computers. Is there any way to read the data without specify the number of bytes to read? Because I don't know the number of bytes before.

Hi,

I you go to "help" > "find examples" you'll find a couple of example VIs called "TCP - Communicator ..." I think you can get inspiration from these.
For instance in the TCP - Communicator - active" you can see that a constant "512" is linked to "bytes to read" and apparently if there is less dat at the specified port, only available data will be read, so you can just count the characters you received.

Hope this will help you 😉
