Hey,
As per my understanding, read(t,1) gives the following error.
Error receiving data from the remote server.
Additional Information: Operation timed out before requested data was received.
read(t,count) reads the number of values specified by count sent to the TCP/IP server t from the client connected to it. You are reading value from the client which is causing the error.
Try using:
read(server,server.NumBytesAvailable)
You can see the documentation and examples provided at
https://www.mathworks.com/help/instrument/tcpserver.read.html
Additionally, you can read from the client when you read data from remote host over TCP/IP. Check this out for more information:
