paho

Does the default PAHO MQTT implementation persist all the messages that are being pushed, until their delivery is confirmed specifically in QoS 2 ? Or if not how is it possible to implement such by our own? UPDATE Since paho android service version 1.1.0 automatic reconnect and offline buffering features are implemented. For more info : https://www.eclipse.org/paho/clients/android/ From the javadoc for MqttClient By default MqttDefaultFilePersistence is used to store messages to a file. If persistence is set to null then messages are stored in memory and hence can be lost if the client, Java

I am using Mosquitto Mqtt along with paho API to receive push messages on android device. But as soon as the network connectivity changes it stops receiving messages. Here are the steps to reproduce the issue with simple test case: 1) Create a simple activity. 2) On Activity StartUp connects to mosquitto test server (test.mosquitto.org:1883) through paho API. 3) Subscribe to some topic. 4) Publish some message to the topic. Result: Mqtt Client receives all the messages published to the topic. Now 5) Disable internet connection on the mobile (mobile data) 6) Publish some message to the topic. 7

I'm using paho to send and receive mqtt messages. So far it has been no problem to send the messages. I have problems with receiving them.My code is: package BenchMQTT; import org.eclipse.paho.client.mqttv3.IMqttDeliveryToken; import org.eclipse.paho.client.mqttv3.IMqttToken; import org.eclipse.paho.client.mqttv3.MqttCallback; import org.eclipse.paho.client.mqttv3.MqttException; import org.eclipse.paho.client.mqttv3.MqttMessage; import org.eclipse.paho.client.mqttv3.MqttClient; public class Test_A_2 implements MqttCallback { MqttClient clientR; MqttClient clientS; public Test_A_2() { } public

I'm trying to implement eclipse.paho in my project to connect Mqtt Broker (Both subscribing and publishing purpose). The problem is, when I using the subscribing feature (Implementing MqttCallback interface), I couldn't figure our how can I reconnect if the connection lost. MqttCallback interface has a connectionLost method, but it is useful for the debug what causes the connection lost. I searched but couldn't find a way to establish auto reconnect. Can you suggest a way or document about this problem? The best way to do this is to structure your connection logic so it lives in a method on it

Does anybody know where I can get some example MQTT client Go (golang) code that does both publish and subscribe in an infinite loop ? I am messaging with a Mosquitto broker running on MacOs. In more detail... Get a message from the network (a topic) Compute something based on that message Send the result of the computation back to the network (topic) Here is the code I am using: package main import ( "fmt" MQTT "github.com/eclipse/paho.mqtt.golang" "os" "time" ) var knt int var f MQTT.MessageHandler = func(client MQTT.Client, msg MQTT.Message) { fmt.Printf("MSG: %s\n", msg.Payload()) text:=

What is the most reliable way to use the Python Paho MQTT client? I want to be able to handle connection interruptions due to WiFi drops and keep trying to reconnect until it's successful. What I have is the following, but are there any best practices I'm not adhering to? import argparse from time import sleep import paho.mqtt.client as mqtt SUB_TOPICS = ("topic/something", "topic/something_else") RECONNECT_DELAY_SECS = 2 def on_connect(client, userdata, flags, rc): print "Connected with result code %s" % rc for topic in SUB_TOPICS: client.subscribe(topic) # EDIT: I've removed this function

When I try the below code to connect to the mosquitto broker, as you know, connecting to the broker might takes few seconds/minutes, and during that time when the button pressed to connect, it remains pressed till the connection established and when the connection established the button released back to its normal state. As far as I know, there are two way for connecting a client using paho java API , the blocking method and unblocking method . my question is, how to use the unblocking method ? beow is my attempt to use the blocking method Code_1 : //mqttFactory public final class
