[paho-dev] .NET Micro Framework Client

["Guy Dillen" <guy.dillen@xxxxxxxxx>]

Hi,

 

I’m trying the Paho Client for .NET (more specific .NET MF v4.2) with a Netduino Plus.

I get the following errors:

 

first chance exception of type 'System.ArgumentException' occurred in System.dll

A first chance exception of type 'System.Net.Sockets.SocketException' occurred in Microsoft.SPOT.Net.dll

Microsoft.SPOT.Net.SocketNative::getaddrinfo

System.Net.Dns::GetHostEntry

uPLibrary.Networking.M2Mqtt.MqttNetworkChannel::.ctor

uPLibrary.Networking.M2Mqtt.MqttClient::Init

uPLibrary.Networking.M2Mqtt.MqttClient::.ctor

uPLibrary.Networking.M2Mqtt.MqttClient::.ctor

MQTTSample.Program::PublishMessage

MQTTSample.Program::Main

 

Code snippet (example from the PAHO site), method called from Main:

 

     private static void PublishMessage(int value)

        {

            // create client instance

            try

            {

                MqttClient client = new MqttClient("198.41.30.241:1883"); // iot.eclipse.org

            

                string clientId = Guid.NewGuid().ToString();

                client.Connect(clientId);

                string strValue = value.ToString();

                // publish a message on "/home/temperature" topic with QoS 2

                client.Publish("/home/temperature", Encoding.UTF8.GetBytes(strValue), MqttMsgBase.QOS_LEVEL_EXACTLY_ONCE, false);

            }

            catch(Exception e)

            {

                Debug.Print(e.StackTrace);

            }

        }

 

Thanks.

Guy
