I write a java tcp server which listen on port XXX to test my opcua driver ,when tcp server receive a message,it will responde some message( It has been tested by java client TCP program);
I implement the function “sendMessage” and “receiveMessage” of Class AbstractReadRequest,
In sendMessage, I use writeToChannel to send the message to the tcp server ,it succeed.
but receiveMessage didn’t run so it indicate there is no responded message arrived ,and in console ,it always shows the message :
TimeoutDaemon ScheduledRequest : request with key "0" failed due to timeout.
What is the problem ,thank you very much
