+Interface MqttCallback

+
+
+
public interface MqttCallback
+ +

+Asynchronous message listener. Classes implementing this interface + can be passed to MqttClient.setCallback(MqttCallback), + which will create a call back on this interface. +

+ +

+

+ +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+Method Summary
+ voidconnectionLost(java.lang.Throwable cause) + +
+          This method is called when the connection to the server is lost.
+ voiddeliveryComplete(MqttDeliveryToken token) + +
+          Called when delivery for a message has been completed, and all + acknowledgements have been received.
+ voidmessageArrived(MqttTopic topic, + MqttMessage message) + +
+          This method is called when a message arrives from the server. + +
+  +

+ + + + + + + + + + + + + + +
+Method Detail
+ +

+connectionLost

+
+public void connectionLost(java.lang.Throwable cause)
+
+
This method is called when the connection to the server is lost. +

+

+
Parameters:
cause - the reason behind the loss of connection.
+
+
+
+ +

+messageArrived

+
+public void messageArrived(MqttTopic topic,
+                           MqttMessage message)
+                    throws java.lang.Exception
+
+
This method is called when a message arrives from the server. + +

+ This method is invoked synchronously by the MQTT client. An + acknowledgment on the network is not sent back to the server until this + method returns cleanly.

+

+ If an implementation of this method throws an Exception, then the + client will be shut down. When the client is next re-connected, any QoS + 1 or 2 messages will be redelivered.

+

+ Any additional messages which arrive while an + implementation of this method is running, will build up in memory, and + will then back up on the network.

+

+ If an application needs to persist data, then it + should ensure the data is persisted prior to returning from this method, as + after returning from this method, the message is considered to have been + delivered, and will not be reproducable.

+

+ It is possible to send a new message within an implementation of this callback + (for example, a response to this message), but the implementation must not + disconnect the client, as it will be impossible to send an acknowledgement for + the message being processed, and a deadlock will occur.

+

+

+
Parameters:
topic - the topic on which the message arrived.
message - the actual message. +
Throws: +
java.lang.Exception - if a terminal error has occurred, and the client should be + shut down.
+
+
+
+ +

+deliveryComplete

+
+public void deliveryComplete(MqttDeliveryToken token)
+
+
Called when delivery for a message has been completed, and all + acknowledgements have been received. The supplied token will be same + token which was returned when the message was first sent, if it was + sent using MqttTopic.publish(MqttMessage). +

+

+
Parameters:
token - the delivery token associated with the message.

+MqttClient

+
+public MqttClient(java.lang.String serverURI,
+                  java.lang.String clientId)
+           throws MqttException
+
+
Creates an MqttClient to connect to the specified address, using the + specified client identifier. The address + should be a URI, using a scheme of either "tcp://" for a TCP connection + or "ssl://" for a TCP connection secured by SSL/TLS. For example: +
    +
  • tcp://localhost:1883
    • +
  • ssl://localhost:8883
    • +
+

+ If the port is not specified, it will + default to 1883 for "tcp://" URIs, and 8883 for "ssl://" URIs. +

+

+ The client identifier should be unique across all clients connecting to the same + server. A convenience method is provided to generate a random client id that + should satisfy this criteria - generateClientId(). As the client identifier + is used by the server to identify a client when it reconnects, the client must use the + same identifier between connections if durable subscriptions are to be used. +

+

+ In Java SE, SSL can be configured in one of several ways, which the + client will use in the following order: +

+ + +

In Java ME, the platform settings are used for SSL connections.

+ +

A default instance of MqttDefaultFilePersistence is used by + the client. To specify a different persistence implementation, or to turn + off persistence, use the MqttClient(String, String, MqttClientPersistence) constructor. +

+

Parameters:
serverURI - the address to connect to, specified as a URI
clientId - the client ID to use +
Throws: +
java.lang.IllegalArgumentException - if the URI does not start with + "tcp://", "ssl://" or "local://". +
java.lang.IllegalArgumentException - if the clientId is null or is greater than 23 characters in length +
MqttException - if any other problem was encountered

+                  MqttClientPersistence persistence)
+           throws MqttException
+
+
Creates an MqttClient to connect to the specified address, using the + specified client identifer and persistence implementation. The address + should be a URI, using a scheme of either "tcp://" for a TCP connection + or "ssl://" for a TCP connection secured by SSL/TLS. For example: +
    +
  • tcp://localhost:1883
    • +
  • ssl://localhost:8883
    • +
  • local://FirstBroker
    • +
+

+ If the port is not specified, it will + default to 1883 for "tcp://" URIs, and 8883 for "ssl://" URIs. +

+

+ The client identifier should be unique across all clients connecting to the same + server. A convenience method is provided to generate a random client id that + should satisfy this criteria - generateClientId(). As the client identifier + is used by the server to identify a client when it reconnects, the client must use the + same identifier between connections if durable subscriptions are to be used. +

+

+ In Java SE, SSL can be configured in one of several ways, which the + client will use in the following order: +

+ + +

In Java ME, the platform settings are used for SSL connections.

+ + The persistence mechanism is used to enable reliable messaging. + For qualities of server (QoS) 1 or 2 to work, messages must be persisted + to disk by both the client and the server. If this is not done, then + a failure in the client or server will result in lost messages. It + is the application's responsibility to provide an implementation of the + MqttClientPersistence interface, which the client can use to + persist messages. If the application is only sending QoS 0 messages, + then this is not needed. + +

An implementation of file-based persistence is provided in the + class MqttDefaultFilePersistence. + If no persistence is needed, it can be explicitly set to null.

+

+

Parameters:
serverURI - the address to connect to, specified as a URI
clientId - the client ID to use
persistence - the persistence mechanism to use. +
Throws: +
java.lang.IllegalArgumentException - if the URI does not start with + "tcp://", "ssl://" or "local://". +
java.lang.IllegalArgumentException - if the clientId is null or is greater than 23 characters in length +
MqttException - if any other problem was encountered

+disconnect

+
+public void disconnect(long quiesceTimeout)
+                throws MqttException
+
+
Disconnects from the server. + This method must not be called from inside MqttCallback methods. +

+ Firstly, the client will wait for all MqttCallback methods to + complete. It will then quiesce for the specified time, to allow for + work which has already been accepted to complete - for example, it will + wait for the QoS 2 flows from earlier publications to complete. After + the quiesce timeout, the client will disconnect from the server. When + the client is next connected, any QoS 1 or 2 messages which have not + completed will be retried.

+

+

+
+
+
+
Parameters:
quiesceTimeout - the amount of time in milliseconds to allow for existing work to finish + before disconnecting. A value of zero or less means the client will + not quiesce. +
Throws: +
MqttException
+
+
+
+ +

+isConnected

+
+public boolean isConnected()
+
+
Determines if this client is currently connected to the + server. +

+

+
+
+
+ +
Returns:
true if connected, false otherwise.
+
+
+
+ +

+getClientId

+
+public java.lang.String getClientId()
+
+
Returns the client ID used by this client. +

+

+
+
+
+ +
Returns:
the client ID used by this client.
+
+
+
+ +

+getServerURI

+
+public java.lang.String getServerURI()
+
+
Returns the address of the server used by this client, as a URI. + The format is the same as specified on the constructor. +

+

+
+
+
+ +
Returns:
the server's address, as a URI String.

+getTopic

+
+public MqttTopic getTopic(java.lang.String topic)
+
+
Gets a topic object which can be used to publish messages. +

When you build an application, + the design of the topic tree should take into account the following principles + of topic name syntax and semantics:

+ +
    +
  • A topic must be at least one character long.
    • +
  • Topic names are case sensitive. For example, ACCOUNTS and Accounts are + two different topics.
    • +
  • Topic names can include the space character. For example, Accounts + payable is a valid topic.
    • +
  • A leading "/" creates a distinct topic. For example, /finance is + different from finance. /finance matches "+/+" and "/+", but + not "+".
    • +
  • Do not include the null character (Unicode \x0000) in + any topic.
    • +
+ +

The following principles apply to the construction and content of a topic + tree:

+ +
    +
  • The length is limited to 64k but within that there are no limits to the + number of levels in a topic tree.
    • +
  • There can be any number of root nodes; that is, there can be any number + of topic trees.
    • +
+

+

+

+
Specified by:
getTopic in interface org.eclipse.paho.client.mqttv3.internal.DestinationProvider
+
+
+
Parameters:
topic - the topic to use, for example "finance/stock/ibm". +
Returns:
an MqttTopic object, which can be used to publish messages to + the topic. +
Throws: +
java.lang.IllegalArgumentException - if the topic contains a '+' or '#' + wildcard character.

+               throws MqttException,
+                      MqttSecurityException
+
+
Subscribes to multiple topics, each of which may include wildcards, + using the specified options. The setCallback(MqttCallback) method should be called + before this method, otherwise any received messages will be discarded. + +

The "topic filter" string used when subscribing + may contain special characters, which allow you to subscribe to multiple topics + at once.

+

The topic level separator is used to introduce structure into the topic, and + can therefore be specified within the topic for that purpose. The multi-level + wildcard and single-level wildcard can be used for subscriptions, but they + cannot be used within a topic by the publisher of a message. +

+
Topic level separator
+
The forward slash (/) is used to separate each level within + a topic tree and provide a hierarchical structure to the topic space. The + use of the topic level separator is significant when the two wildcard characters + are encountered in topics specified by subscribers.
+ +
Multi-level wildcard
+

The number sign (#) is a wildcard character that matches + any number of levels within a topic. For example, if you subscribe to finance/stock/ibm/#, you receive + messages on these topics:

   finance/stock/ibm
   finance/stock/ibm/closingprice
   finance/stock/ibm/currentprice
+

+

The multi-level wildcard + can represent zero or more levels. Therefore, finance/# can also match + the singular finance, where # represents zero levels. The topic + level separator is meaningless in this context, because there are no levels + to separate.

+ +

The multi-level wildcard can + be specified only on its own or next to the topic level separator character. + Therefore, # and finance/# are both valid, but finance# is + not valid. The multi-level wildcard must be the last character + used within the topic tree. For example, finance/# is valid but finance/#/closingprice is + not valid.

+ +
Single-level wildcard
+

The plus sign (+) is a wildcard character that matches only one topic + level. For example, finance/stock/+ matches finance/stock/ibm and finance/stock/xyz, + but not finance/stock/ibm/closingprice. Also, because the single-level + wildcard matches only a single level, finance/+ does not match finance.

+ +

Use + the single-level wildcard at any level in the topic tree, and in conjunction + with the multilevel wildcard. Specify the single-level wildcard next to the + topic level separator, except when it is specified on its own. Therefore, + and finance/+ are + both valid, but finance+ is not valid. The single-level + wildcard can be used at the end of the topic tree or within the topic tree. + For example, finance/+ and finance/+/ibm are both valid.

+
+
+

+

+

+
+
+
+
Parameters:
topicFilters - the topics to subscribe to, which can include wildcards.
qos - the qualities of service levels at which to subscribe. +
Throws: +
MqttException - if there was an error registering the subscription. +
java.lang.IllegalArgumentException - if the two supplied arrays are not the same size. +

+Interface MqttClientPersistence

+
+
All Known Implementing Classes:
MqttDefaultFilePersistence
+
+
+
+
public interface MqttClientPersistence
+ +

+Represents a persistent data store, used to store outbound and inbound messages while they + are in flight, enabling delivery to the QOS specified. You can specify an implementation + of this interface using MqttClient.MqttClient(String, String, MqttClientPersistence), + which the MqttClient will use to persist QoS 1 and 2 messages. +

+ If the methods defined throw the MqttPersistenceException then the state of the data persisted + should remain as prior to the method being called. For example, if put(String, MqttPersistable) + throws an exception at any point then the data will be assumed to not be in the persistent store. + Similarly if remove(String) throws an exception then the data will be + assumed to still be held in the persistent store.

+

+ It is up to the persistence interface to log any exceptions or error information + which may be required when diagnosing a persistence failure.

+

+ +

+

+ +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+Method Summary
+ voidclear() + +

+          Returns whether or not data is persisted using the specified key.
+ MqttPersistableget(java.lang.String key) + +
+          Gets the specified data out of the persistent store.
+ java.util.Enumerationkeys() + +
+          Returns an Enumeration over the keys in this persistent data store.
+ voidopen(java.lang.String clientId, + java.lang.String serverURI) + +
+          Initialise the persistent store. +
+ voidput(java.lang.String key, + MqttPersistable persistable) + +

+setKeepAliveInterval

+
+public void setKeepAliveInterval(int keepAliveInterval)
+
+
Sets the "keep alive" interval. + This value, measured in seconds, defines the maximum time interval + between messages sent or received. It enables the client to + detect that if the server is no longer available, without + having to wait for the long TCP/IP timeout. The client will ensure + that at least one message travels across the network within each + keep alive period. In the absence of a data-related message during + the time period, the client sends a very small "ping" message, which + the server will acknowledge. +

The default value is 60 seconds

com.ibm.ssl.keyStoreType
+
Type of key store, for example "PKCS12", "JKS", or "JCEKS".
+ +
com.ibm.ssl.keyStoreProvider

+ +
com.ibm.ssl.trustStorePassword
+
The password for the TrustStore object that you want the + TrustManager to use. The password can either be in plain-text, + or may be obfuscated using the static method: + com.ibm.micro.security.Password.obfuscate(char[] password). + This obfuscates the password using a simple and insecure XOR and Base64 + encoding mechanism. Note that this is only a simple scrambler to + obfuscate clear-text passwords.
+ +
com.ibm.ssl.trustStoreType
+
The type of KeyStore object that you want the default TrustManager to use. + Same possible values as "keyStoreType".
+ +
com.ibm.ssl.trustStoreProvider
+

+ +
com.ibm.ssl.keyManager
+
Sets the algorithm that will be used to instantiate a KeyManagerFactory object + instead of using the default algorithm available in the platform. Example values: + "IbmX509" or "IBMJ9X509". +
+ +
com.ibm.ssl.trustManager
+
Sets the algorithm that will be used to instantiate a TrustManagerFactory object + instead of using the default algorithm available in the platform. Example values: + "PKIX" or "IBMJ9X509". +

public class MqttDefaultFilePersistence
extends java.lang.Object
implements MqttClientPersistence
+ +

+An implementation of the MqttClientPersistence interface that provides + file based persistence. + + A directory is specified when the Persistence object is created. When the persistence + is then opened (see open(String, String)), a sub-directory is made beneath the base + for this particular client ID and connection key. This allows one persistence base directory + to be shared by multiple clients. + + The sub-directory's name is created from a concatenation of the client ID and connection key + with any instance of '/', '\\', ':' or ' ' removed. +

+ +

+

+ +

+ + + + + + + + + + + + + + + + + + + +

+Interface MqttDeliveryToken

+
+
+
public interface MqttDeliveryToken
+ +

+Provides a mechanism for tracking the delivery of messages. + + Calls to MqttTopic.publish(MqttMessage) + return after the message has been sent, but do not wait for acknowledgements + to be received. This allows the + client to have multiple messages in-flight at one time. + + In order to track the delivery of a message, those methods + return an instance of this class which can be used in one of two ways: +

+

+ +

+

+ +

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+Method Summary
+ MqttMessagegetMessage() + +
+          Returns the message associated with this token, or null if the message has + already been successfully sent.
+ booleanisComplete() + +
+          Returns whether or not the delivery has finished.
+ voidwaitForCompletion() + +
+          Blocks the current thread until the message this is the token + for completes delivery.
+ voidwaitForCompletion(long timeout) + +
+          Blocks the current thread until the message this is the token + for completes delivery. +

+                              MqttSecurityException
+
+
Blocks the current thread until the message this is the token + for completes delivery. + This will only block for specified timeout period. If the delivery has not + completed before the timeout occurs, this method will return - the + isComplete() method can be used to determine if the delivery is + complete, or if the wait has timed out. +

+

+
Parameters:
timeout - the maximum amount of time to wait for, in milliseconds. +
Throws: +
MqttException - if there was a problem completing delivery of the message +
MqttSecurityException

+
+public void setPayload(byte[] payload)
+
+
Sets the payload of this message to be the specified byte array. +

+

+
Parameters:
payload - the payload for this message. +

+
+
+
+ +

+isRetained

+
+public boolean isRetained()
+
+
Returns whether or not this message should be/was retained by the server. + For messages received from the server, this method returns whether or not + the message was from a current publisher, or was "retained" by the server as + the last message published on the topic. +

+

+ +
Returns:
true if the message should be, or was, retained by + the server.
See Also:
setRetained(boolean)
+
+
+
+ +

+setRetained

+
+public void setRetained(boolean retained)
+
+
Whether or not the publish message should be retained by the messaging engine. + Sending a message with the retained set to false will clear the + retained message from the server. The default value is false +

+

+
Parameters:
retained - whether or not the messaging engine should retain the message. +
Throws: +
java.lang.IllegalStateException - if this message cannot be edited

+
+
+
+ +

+setQos

+
+public void setQos(int qos)
+
+
Sets the quality of service for this message. +
    +
  • Quality of service 0 - indicates that a message should + be delivered at most once (zero or one times). The message will not be persisted to disk, + and will not be acknowledged across the network. This QoS is the fastest, + but should only be used for messages which are not valuable - note that + if the server cannot process the message (for example, there + is an authorization problem), then an + MqttCallback.deliveryComplete(MqttDeliveryToken). + Also known as "fire and forget".
    • + +
  • Quality of service 1 - indicates that a message should + be delivered at least once (one or more times). The message can only be delivered safely if + it can be persisted, so the application must supply a means of + persistence using MqttConnectOptions. + If a persistence mechanism is not specified, the message will not be + delivered in the event of a client failure. + The message will be acknowledged across the network. + This is the default QoS.
    • + +
  • Quality of service 2 - indicates that a message should + be delivered once. The message will be persisted to disk, and will + be subject to a two-phase acknowledgement across the network. + The message can only be delivered safely if + it can be persisted, so the application must supply a means of + persistence using MqttConnectOptions. + If a persistence mechanism is not specified, the message will not be + delivered in the event of a client failure.
    • + + If persistence is not configured, QOS 1 and 2 messages will still be delivered + in the event of a network or server problem as the client will hold state in memory. + If the MQTT client is shutdown or fails and persistence is not configured then + delivery of QOS 1 and 2 messages can not be maintained as client side state will + be lost. +

    +

    +
    Parameters:
    qos - the "quality of service" to use. Set to 0, 1, 2. +
    Throws: +
    java.lang.IllegalArgumentException - if value of QoS is not 0, 1 or 2. +
    java.lang.IllegalStateException - if this message cannot be edited
    +
    +
+

+toString

+
+public java.lang.String toString()
+
+
Returns a string representation of this message. +

+

+ +
Returns:

+isDuplicate

+
+public boolean isDuplicate()
+
+
Returns whether or not this message might be a duplicate of one which has + already been received. This will only be set on messages received from + the server. +

+

+ +
Returns:
true if the message might be a duplicate.

+Interface MqttPersistable

+
+
+
public interface MqttPersistable
+ +

+Represents an object used to pass data to be persisted across the + MqttClientPersistence + interface. +

+ When data is passed across the interface the header and payload are + separated, so that unnecessary message copies may be avoided. + For example, if a 10 MB payload was published it would be inefficient + to create a byte array a few bytes larger than 10 MB and copy the + MQTT message header and payload into a contiguous byte array.

+

+ When the request to persist data is made a separate byte array and offset + is passed for the header and payload. Only the data between + offset and length need be persisted. + So for example, a message to be persisted consists of a header byte + array starting at offset 1 and length 4, plus a payload byte array + starting at offset 30 and length 40000. There are three ways in which + the persistence implementation may return data to the client on + recovery: +

+Package org.eclipse.paho.client.mqttv3 Description +

+ +

+Contains an API for connecting to a server which implements the MQTT V3 +protocol. + +

+The MQ Telemetry Transport (MQTT) is a lightweight publish/subscribe protocol +flowing over TCP/IP for remote sensors and control devices through low +bandwidth communications. MQTT is used by specialized applications on +small footprint devices that require a low bandwidth communication, +typically for remote data acquisition and process control. +

+

+A typical system might comprise several hundred client devices communicating +with a single server or "broker", where each client is identified +by a unique ID. +

+

The basic means of operating the client is as follows:

+
    +
  1. Create an instance of MqttClient, providing + the address of the server and a unique client identifier.
    2. +
  2. Connect to the server
    3. +
  3. Exchange messages with the server. + +
    4. +
  4. Disconnect from the server.
    5. +
+

+

Examples

+

Publish a message, at most once

+

In the following code snippet, a simple message is published to the server, +using defaults wherever possible.

+
	MqttClient client = new MqttClient("tcp://localhost:1883", "SampleClient");
+	client.connect();
+	MqttMessage message = new MqttMessage("Hello world");
+	message.setQos(0);
+	client.getTopic("foo/bar").publish(message);
+	client.disconnect();
 + +

This is the fastest way of publishing messages, +but is also the least reliable. There is no assurance that the message will actually be +delivered, and no exception will be thrown if the server refuses the message, or if the +network connection fails.

+ +

Publish a message, once and only once (single threaded)

+

In the following code snippet, a message is published to the server +at QoS 2, which is the most reliable delivery mechanism. +In order to achieve this, the message needs to be persisted by the client. +A default implementation of persistence is provided by MqttDefaultFilePersistence. +This will be used by the client unless an alternative is supplied.

+

Publishing reliably is more complex, and most of the code is used to handle +error conditions. The key thing to notice is the two-stage delivery: the first +stage gives the message to the client. After this, the client is responsible for +delivering the message to the server. The second stage is about determining +success or failure.

+ +
+	MqttClient client = null;
+	try {
+		// Create a client to communicate with a broker at the specified address
+		client = new MqttClient("tcp://localhost:1883", "SampleClient");
+		// Connect to the broker
+		client.connect();
+	} catch (MqttException ex) {
+		System.err.println("Could not connect");
+	}
+	
+	if ((client != null) && client.isConnected()) {
+		MqttTopic topic = client.getTopic("foo/bar");
+		MqttDeliveryToken token = null;
+		// Create message and set quality of service to deliver the message once
+		MqttMessage message = new MqttMessage("Hello world");
+		message.setQos(2);
+		
+		try {
+			// Give the message to the client for publishing.  For QoS 2,
+			// this will involve multiple network calls, which will happen 
+			// asynchronously after this method has returned.
+			token = topic.publish(message);
+		}
+		catch (MqttException ex) {
+			// Client has not accepted the message due to a failure
+			// Depending on the exception's reason code, we could always retry
+			System.err.println("Failed to send message");
+		}
+		
+		if (token != null) {
+			boolean keepTrying = true;
+			do {
+				try {
+					// Wait for the message delivery to complete
+					token.waitForCompletion();
+					System.out.println("Message delivery complete");
+				}
+				catch (MqttException deliveryException) {
+					int reasonCode = deliveryException.getReasonCode();
+					// TODO: Retry the message, or decide to stop trying
+					System.err.println("Message delivery failed");
+					if (client.isConnected() == false) {
+						try {
+							// Re-connect to the server
+							client.connect();
+						}
+						catch (MqttException connectException) {
+							// Can't reconnect, so give up.  If and when the 
+							// client does reconnect, the message delivery
+							// will automatically continue
+							keepTrying = false;
+						}
+					}
+				}
+			} while (!token.isComplete() && keepTrying);
+		}
+	}
 + +

Publish a message, once and only once (multi-threaded)

+

In the following code snippet, a message is published to the server +at QoS 2, which is the most reliable delivery mechanism. +The application uses a callback to asynchronously be notified +when delivery of a message has been completed.

+ +

+A default implementation of persistence is provided by MqttDefaultFilePersistence. +This will be used by the client unless an alternative is supplied.

+ +
+public class SampleClient implements MqttCallback {
+	public void run() {
+		MqttClient client = null;
+		try {
+			// Create a client to communicate with a broker at the specified address
+			client = new MqttClient("tcp://localhost:1883", "SampleClient");
+
+			// Connect to the broker
+			client.connect();
+
+			// Setup a callback
+			client.setCallback(this);
+
+		} catch (MqttException ex) {
+			System.err.println("Could not connect");
+		}
+		
+		if ((client != null) && client.isConnected()) {
+			MqttTopic topic = client.getTopic("foo/bar");
+			// Create message and set quality of service to deliver the message once
+			MqttMessage message = new MqttMessage("Hello world");
+			message.setQos(2);
+	
+			try {
+				// Give the message to the client for publishing. For QoS 2, this
+				// will involve multiple network calls, which will happen
+				// asynchronously after this method has returned.
+				topic.publish(message);
+			} catch (MqttException ex) {
+				// Client has not accepted the message due to a failure
+				// Depending on the exception's reason code, we could always retry
+				System.err.println("Failed to send message");
+			}
+		}
+	}
+
+	public void connectionLost(Throwable cause) {
+		// TODO: Implement reconnection logic
+		System.err.println("Connection lost");
+	}
+
+	public void deliveryComplete(MqttDeliveryToken token) {
+		System.out.println("Delivery complete");
+	}
+
+	public void messageArrived(MqttTopic topic, MqttMessage message) throws Exception {
+	}
+}
