I am using QModbusClient object as a modbus tcp master. I refered the example ,but it implement by async mode(connect to finished signals). But now ,because of some reason ,I want to wait the reply blocked.I tryied call "isFinished" API like :
while(reply->isFinished()){
//wait
}
, but it always retured false，I don‘t know why，Any suggestion？
THANKS！！

Connect the finished sginal from the reply with https://doc.qt.io/qt-6/qeventloop.html#exit then start the request and the local event loop (https://doc.qt.io/qt-6/qeventloop.html#exec>)
