  • Hi David,

    Without any code, all I do is make a few suggestions and point you to my blog post.

    You need to be reading the data into a buffer, in a loop. Hopefully the data coming in has start/end delimiters to indicate the start and end of a transmission, typically STX (which is a (char)2) and ETX (which is a (char)3), so that you can parse out an entire transmission.

    See my blog post (with code snippets) on the subject: https://geek-goddess-bonnie.blogspot.com/2018/12/event-driven-tcp.html

  • TCP should do this for you automatically.  That's just part of the protocol.  Do you have some higher level protocol sitting on top of TCP?
