Hi there, i'm new to twisted, but i want to use it in a project for dealing with the socket connection to a server for receiving and sending data. I already did some projects in Delphi and there you have an build-in eventdriven socket class. Python itself lacks at this feature (afaik) and so i stumpled upon twisted. Since its only a small part of my task, im looking for an easy solution but after consulting google for two days and testing around im still failing at get it working. What i got so far: class ControllerProtocol(Protocol): def connectionMade(self): # send Greeting self.factory.isConnected = True self.transport.write("hello, world!") def dataReceived(self, data): "Parse received data and send corresponding Message." self.transport.write(self.factory.reactOnReceive(data)) def connectionLost(self, reason): #try to reconnect self.factory.isConnected = False print "connection lost" def sendMessage(self, data): print 'Send:', data self.transport.write(data) class Communicator(ClientFactory): protocol = ControllerProtocol def __init__(self, Host, Port): if isinstance(Host, str) and isinstance(Port, int) : self.myHost = Host self.myPort = Port self.isConnected = False print 'Going To connect' self.connectToMother() def connectToMotherShip(self): reactor.connectTCP(self.myHost, self.myPort, self) reactor.run() def buildProtocol(self, addr): p = ClientFactory.buildProtocol(self, addr) self.connectedProtocol = p return p def sendMessage(self, Message): self.connectedProtocol.SendMessage(Message) def reactOnReceive(self, String): #here i parse the received string for different requests after converting it to json and update values of the operator pass class Operator: def __init__(self): self.myCommunicator = Communicator("192.168.1.12", 815) do other stuff ... I want an Operator Object that builds the Communicator. The communicator updates values of the Operator asynchronously if it receives messages. Each 10 secs the Operator will initiate a Communicator.sendMessage to send a status information to the server. Two questions: 1) Is it possible to solve my task like this with twisted and if so, how do I get my Communicator to not block my Operator? 2) If twisted is not the easiest way for this approach, do i have alternatives? I want at least something event driven. I also read about the asyncore packages, but people often recommend twisted over asyncore. I simply want to send and receive message with a "threaded" communicator class, while doing other stuff in my Operator. Thanks a lot for your help, Toni
