Re: [paho-dev] Paho Mqtt Client Issue

[Deepak Kumhar <deepak.kumhar@xxxxxxxxxxxxx>]

VerneMq broker we are using. We have successfully proceed all data without disconnecting while we used node client. 
The issue is with Eclipse java paho Mqtt client only and only when we are using QOs 1. For qos 0 it is working fine.

Hello, 
We are trying to publish message with Qos 1, messages are being publish successfully but just after each publish client is getting connection lost callback (disconnecting) which was not there  in case of when we were using Qos 0. 

If you could guide us if anything more configuration require while dealing with Qos  1 would be helpful. 

Below is the common configuration for both case. 

MqttConnectOptions options = new MqttConnectOptions();
options.setUserName("ourusername");
options.setPassword("ourPassword");
options.setMqttVersion(MqttConnectOptions.MQTT_VERSION_3_1);
options.setAutomaticReconnect(false);
options.setCleanSession(false);
options.setKeepAliveInterval(900);

String tmpDir = System.getProperty("java.io.tmpdir");
MqttDefaultFilePersistence dataStore = new MqttDefaultFilePersistence(tmpDir);

MqttClient client = new MqttClient(url,client_id,dataStore);client.setTimeToWait(15000);client.connect(options);
 

MqttMessage message = new MqttMessage(ourPayload);message.setQos(1); //0 and 1 /* working fine in case of 0*/client.publish(ourtopic,message);
