QThread sync communication + one extra event

[qtprogrammer123]

Hi,
Im using QThread for sync QSerialPort communication - i need it. But i have one very long operation, and i dont wonna stop serial communication with 2 minutes timeout

if (serial.waitForReadyRead(waitTimeout)) {
            QByteArray responseData = serial.readAll();
            while (serial.waitForReadyRead(10))
             responseData += serial.readAll();

I need some way to recive this one special operation in async way.

QThread is blocked until next data send by wait condition

 mutex.lock();
 condition.wait(&mutex);

I can recognize this anserw by data inside frame

@qtprogrammer123 said in QThread sync communication + one extra event:

Then why do you use blocking calls? QSerialPort provides asynchronous API, use it.

Like i wrote it must be sync communication in other thread, application need it. I using serial in 5 places in code and all of them need take serial for communication with device and wait for anserw, anserw are similar and i cant recognize it. Only 6 operation not

@qtprogrammer123 I have no idea how you would use same serial port at the same time for synchronous and asynchronous communication...

[qtprogrammer123]

Its only one async operation - this command not block device, but i recive anserw after few minutes. Before that i wonna still use my sync communication for regular operation

Then use async everywhere.
