Unable to open the port on MAC #83

Closed SteMMo33 closed 3 months ago

SteMMo33 commented 6 months ago

Describe the bug I'm not able to open the serial port on MAC 12.7.4 and Qt.

From my code I get all the serial ports recalling the function QSerialPortInfo::availablePorts() This call returns always couples of ports: example:

">> 'cu.Bluetooth-Incoming-Port' - loc: '/dev/cu.Bluetooth-Incoming-Port' - desc: ''"
">> 'tty.Bluetooth-Incoming-Port' - loc: '/dev/tty.Bluetooth-Incoming-Port' - desc: ''"
">> 'cu.usbmodem00000000001A1' - loc: '/dev/cu.usbmodem00000000001A1' - desc: 'VIOS118 ComPort'"
">> 'tty.usbmodem00000000001A1' - loc: '/dev/tty.usbmodem00000000001A1' - desc: 'VIOS118 ComPort'"

If I open a port I always have an error, regardless the selected port:

TerminalProt] Open '/dev/cu.usbmodem00000000001A1'
open port error: Unable to open : No such file or directory
[TerminalProt] Open ret: 0
[TerminalProt] Open '/dev/tty.usbmodem00000000001A1'
open port error: Unable to open : No such file or directory
TerminalProt] Open ret: 0

The code is very simply:

               std::cout << "[TerminalProt] Open '" << serial_port_parameters.PortName << "'" << std::endl;

        if (_serialPort.isOpen())
            _serialPort.close();
                _serialPort.setPortName(serial_port_parameters.PortName.c_str());
        bool ret = _serialPort.open();
        std::cout << "[TerminalProt] Open ret: " << ret << std::endl;

Please, any idea? Thanks!

Could you test the example CommQT( or CommNoGui) of CSerialPort v4.3.1 ? The example project at CSerialPort/examples/CommQT. CommNoGui is console(no gui) example, and default output more debug info.

Hello, sorry for my delay. This is the results of my tests.

-- Windows -- Everything is running ok.

-- MAC -- I need to apply a conditioned code:

#ifdef WIN32
        ui->cmbSeriali->addItem(Port.portName() + " - " + Port.description(), Port.portName());
#elif defined __APPLE__
        ui->cmbSeriali->addItem(Port.portName() + " - " + Port.description(), Port.systemLocation());
#endif

cause MAC uses systemLocation as 'device' name. This is some of my debug info:

Effectively I absolutely need a 'non standard' baud rate (1177): but under Windows I don't have this problem, is it a MAC problem??

Thanks

itas109 commented 5 months ago

non standard baud rate only support windows and linux now. I need some time to support it on macos.

SteMMo33 commented 5 months ago

ok itas109, thanks.

Anyway, I'm using the package by vcpkg and right now there the version is one step behind. (I don't know the dynamics for the deploy on vcpkg ...) Thanks!

itas109 commented 5 months ago

Mac OS X Tiger(10.4.11) support non-standard baud rate.

You could try the master code.

vcpkg get github master

vcpkg install cserialport --head
SteMMo33 commented 5 months ago 
stefano@MacMiniNewdep vcpkg % vcpkg install cserialport --head

The following packages are already installed:
    cserialport:x64-osx@4.3.0#1

but it is not aligned with the version on GitHub (4.3.1)

itas109 commented 5 months ago

try remove fisrt, then install --head

vcpkg remove cserialport
vcpkg install cserialport --head

Here I'm under Windows but again the installed version is 4.3.0#1
