In case of any issues, the error() or timeout() signal is emitted.

The result is provided by the response() signal. The transaction() method can be called to start up the new sender transaction with the desired request. This class provides signals for responding and reporting errors. Subclass that provides API for scheduling requests to the receiver. Void transaction( const QString &portName, int waitTimeout, const QString &request) The sender application initiates the transfer request via the serial port to the receiver application and waits for response.Įxplicit SenderThread( QObject *parent = nullptr) This application is the sender which demonstrates the work paired with the receiver application The blocking serial programming API often leads to simpler code, but it should only be used in non-GUI threads to keep the user interface responsive. The purpose of this example is to demonstrate how to simplify your serial programming code without losing the responsiveness of the user interface. TheĮxample illustrates the asynchronous alternative. In this example, the synchronous alternative is demonstrated. ) to suspend the calling thread until the operation has completed. In headless and multithreaded applications, the wait method can be called (in this case, When the data is sent to the serial port, the TheĬlass emits a signal when the operation is finished. Operations are scheduled and performed when the control returns to the Qt event loop. The asynchronous (non-blocking) alternative.
