When you have a tcpclient connection that exists in the MATLAB workspace or is saved as a class property or app property, the tcpclient object might not be accessible in a different function or app callback. In
Turn the callback off. configureCallback(t,"off") Verify that the callback is off. t.BytesAvailableFcnMode ans = "off" Input Arguments collapse all TCP/IP client, specified as atcpclientobject. Example:configureCallback(t,"byte",128,@callbackFcn)sets thecallbackFcncallback to trigger each...

I create a tcpclient connection: t = tcpclient('address', port); And I send a request to the server (which starts automatically to send data): write( t, 'request' ); I want to have a callback function triggered by a bytes available event: configureCallback( t, "terminator", ...
write(t,data) 从连接到远程主机的 tcpclient 对象 t 发送 N 维数据矩阵。此函数一直等到指定的值写入远程主机。 示例 全部折叠 读取并写入 uint8 数据 创建一个名为 t 的 TCP/IP 对象,通过端口 7 连接到 TCP/IP 回显服务器。这要求您让 echotcpip 服务器在端口 7 上运行。 t = tcpclient('localhost'...

使用configureCallback 函数为与远程主机的通信设置回调函数和触发条件。使用flush 函数刷新缓冲区,以便与远程主机通信。通过创建一个连接到 TCP/IP 回显服务器的 tcpclient 对象、向其写入数据和从中读取数据,开始使用 TCP/IP 客户端接口。echotcpip("on",3030)t = tcpclient("localhost",3030)write(t,1:5,"...
