I am using MQTT.fx and
"test.mosquitto.org"
locally as a broker. Now i want to send a message from the broker to Visual Studio (where I am connected with the client/broker). How does that work? What I have since now is:
Edit: Obviously
//await client.PublishAsync(new MqttApplicationMessage(topic, Encoding.UTF8.GetBytes($"{message}")), MqttQualityOfService.ExactlyOnce); //QOS 2
is not working at the moment...
private async void OnButton2Clicked(object sender, EventArgs e)
{
try
{
testLabel2.Text = "test";
await client.SubscribeAsync(topic, MqttQualityOfService.ExactlyOnce); //QOS 2
//await client.PublishAsync(new MqttApplicationMessage(topic, Encoding.UTF8.GetBytes($"{message}")), MqttQualityOfService.ExactlyOnce); //QOS 2
OnMessageReceived();
}
catch (Exception ex)
{
testLabel2.Text = "Ausnahme gefunden: " + ex.Message;
}
}
///////////////////////////////////////////////
private void OnMessageReceived()
{
MessagingCenter.Subscribe<IMqttClient>(topic, "Hallooo", (sender) =>
{
testLabel2.Text = "Du hast eine Nachricht bekommen";
});
}
