If you're using UDP, then you can ask the glib mainloop to call your callback whenever there is data available on the socket. In the python bindings you'll want to use glib.io_add_watch. Then your callback will run whenever new messages arrive from your device. Cheers Grahame -- To unsubscribe send a mail to [email protected]
