That is hard to believe as the chat example only uses
SendText()/ReceiveText() and not SendBuf()/ReceiveBuf().
You can use it as a start, but as soon as you have a connection
you have to better the code. In your own interest add the
suggested checks.

Sorry but I do not understand above sentence.

You are trying to reconnect in that thread. Using a terible Slep().
I do not see that you use the OnDisConnect event. Try to use that
event to reconnect again. But not immediately. Start a timer and
in the timer event try to set Activbe to true.

That is no answer to my question as you did not tell where how an
acknowledgement is received. Repeat: Where and when do you call
TCPClientSocketSend() ?

Please add the checks and try OnDisConnect and so.
