my qt code like this … connect(socket, SIGNAL(readyRead()), this, SLOT(readBluetoothDataEvent()) ); … void Widget::readBluetoothDataEvent() { QByteArray line = socket->readAll(); // std::string comStr=line.toStdString(); char *aa; aa=line.data(); std::cout<<aa<<std::endl; when i send data "4321n" from ESP32 via bluetooth, i got result like this: 4 3 2 1 So why readyread() emit every one charactor?

I am replacing old code to linux. I was using: server_host = getipnodebyname(host.c_str(), AF_INET, 0, &err_num); and server_host = getipnodebyaddr(addr, sizeof(INET_ADDRSTRLEN), AF_INET, &err_num); that it has to be replaced by the new getaddrinfo(). At moment I added: struct addrinfo *p_addr = (struct addrinfo *) NULL; struct addrinfo hints={0}; //Initialize the addrinfo hints char addr[INET_ADDRSTRLEN]={0}; int ..
BACKGROUND I am building a basic MFC application which helps me to run tests. The GUI is extremely spartaic. One button to START and another button to STOP the test, plus a static text object to display a few letters and digits indicating what stage the test is performing. This has been working satisfactorily for ..
I am currently working on web server http project. I noticed something with my siege stress test when I stop it with ctrl c. I am using Epoll for multiplexing. A client socket (let’s say fd = 6), for whom I received an EPOLLIN events via epoll returns 0 after a recv. When it happens, ..
