Write one binblock of data from TCP/IP server
writes a binblock of
data in the form specified by
datatype from the TCP/IP server
t to the client
connected to it. The value of the
Connected property of
t must be
true) before you
can write from it. The function suspends MATLAB® execution until the specified values are written to the remote host.
Create a TCP/IP server that listens for connections at
localhost and port 4000.
server = tcpserver("localhost",4000)
server = TCPServer with properties: ServerAddress: "127.0.0.1" ServerPort: 4000 Connected: 0 ClientAddress: "" ClientPort:  NumBytesAvailable: 0 Show all properties, functions
Create a TCP/IP client to connect to your server object using
tcpclient. You must specify the same IP address and port number you use to create
client = tcpclient("localhost",4000)
client = tcpclient with properties: Address: 'localhost' Port: 4000 NumBytesAvailable: 0 Show all properties, functions
Write the values
[1,2,3,4,5] from the server to the client by writing it to the
server object as a binblock in
Write another binblock of data. Write the values
[6,7,8,9,10] as double data.
Since the client is connected to the server, the data you write to the server is available to be read from the
client object. Read the first binblock of data.
ans = 1×5 1 2 3 4 5
Read a binblock of data again to return the second set of values. Specify the data as
ans = 1×5 6 7 8 9 10
t— TCP/IP server
TCP/IP server, specified as a
writebinblock(t,1:5,"uint8") writes a binblock of data to
the TCP/IP client connected to the server
data— Numeric or ASCII data
Nnumeric array | character vector | string scalar
Numeric or ASCII data, specified as a 1-by-
N vector of numeric
values or as a character vector or string scalar of text. For all numeric
data is a row vector of
writebinblock(t,1:5,"uint8") writes the values
datatype— Size and format of each value
Size and format of each value, specified as a character vector or string.
datatype determines the number of bytes to write for each value
and the interpretation of those bytes as a MATLAB data type.
writebinblock(t,1:5,"double") writes the values
[1,2,3,4,5] as double data.
