writebinblock
Description
writebinblock(
writes a binblock of t
,data
,datatype
)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 1
(true
) before you
can write from it. The function suspends MATLAB® execution until the specified values are written to the remote host.
Examples
Write Binblock of Data from TCP/IP Server
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 server
.
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 uint8
format.
writebinblock(server,1:5,"uint8")
Write another binblock of data. Write the values [6,7,8,9,10]
as double data.
writebinblock(server,6:10,"double")
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.
readbinblock(client)
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 double
.
readbinblock(client,"double")
ans = 1×5
6 7 8 9 10
Input Arguments
t
— TCP/IP server
tcpserver
object
TCP/IP server, specified as a tcpserver
object.
Example: writebinblock(t,1:5,"uint8")
writes a binblock of data to
the TCP/IP client connected to the server t
.
data
— Numeric or ASCII data
1-by-N
numeric 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
datatype
types, data
is a row vector of
values.
Example: writebinblock(t,1:5,"uint8")
writes the values
[1,2,3,4,5]
.

[1,2,3,4,5]
as double data.
