Iot c# to c++

[autoprog]

hi,
my IoT c# to c++, how to

    private const string device_aws_id = "93941848-4231-4086-af28-9ff41a506000";
    private const string IotEndpoint = "aabbccddeeff-ats.iot.sa-east-1.amazonaws.com";
    private const int BrokerPort = 8883;
    private const string to_device_master = "tx/"; 
    string cer = "D:/.../certificate.pfx";
    string ca  = "D:/.../root.pem";

            var clientCert = new X509Certificate2(cer, @"");
            var caCert = X509Certificate.CreateFromCertFile(ca);
            client = new MqttClient(IotEndpoint, BrokerPort, true, caCert, clientCert, MqttSslProtocols.TLSv1_2);
            client.MqttMsgPublishReceived += client_MqttMsgPublishReceived;
            client.ProtocolVersion = MqttProtocolVersion.Version_3_1;
            client.Connect(device_aws_id);
            client.Subscribe(new[] { to_device_master }, new[] { MqttMsgBase.QOS_LEVEL_AT_LEAST_ONCE });

how to do without using argument. (argc/argv)
set const var and path file.

whats example in sample to use.
my difficulty is choosing the type of code, and the other is to set and leave the variables fixed using (cmdUtils).

thanks,
Carlos.

how to do without using argument. (argc/argv)

In the above code snippet it looks like you correctly removed argc/argv by using the correct strings/ints.

whats example in sample to use.

You can start with the basic_connect and build on that from the other samples. You don't have to use cmdUtils at all. It just tried to simplify what is shown in each sample by moving the connection code to anther file.

hi,
Im testing basic_connect.
connected a broker ok, problems publish.

seee code,

policies for test

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iot:*",
      "Resource": "*"
    }
  ]
} 


thanks,
Carlos.

It looks like you are trying to publish a message which is the next step after you get the connection set up. For this you don't want to use the basic_connect sample, but rather the pub_sub sample.
We have two samples that show how to do this:

• MQTT3 pub_sub
• MQTT5 pub_sub
  please include any errors that you are seeing with the publish?

hello Joseph, both examples work very well.

I need one more help.
I created project with CMAKE for exe.

cmake CMakeLists.txt
would like to know how to create the CEMAKE project for the library.

I need process using IOT in a library.

thanks,
Carlos.

We have a CMakeLists.txt for each sample. For example here is the CMakeLists.txt for the MQTT3 pub_sub

hi,
both projects for executable I tested and it works ok.

now, i need to create project cmake for dynamic library to use with my executable.
LoadLibrary style.
IoT in library.

or create project library with Visual Studio and add SDK v2 pub_sub.
how to add pub_sub in my library module.

thanks,
Carlos.
