Re: [paho-dev] MQTT reconnect logic

[Marc L Cohen <mlcohen@xxxxxxxxxx>]

You don't need to disconnect. The connection failure already caused a disconnect. All you should need to do is reconnect using the existing client.

Thanks Marc .  connectionLost would be a the right way to do.
 
Since I’m using persistence client, I guess I need to disconnect first and the client using same parameters.
Just want to clarify.
 
 
I  came across this client http://mqtt-client.fusesource.org/
Which says it reconnects by itself. I would be gr8 if paho could provide it.

You need to provide code to do the reconnect. I do that in the connectionLost method on the callback.

Hi All,
 
I need help from you to understand reconnect logic.
 
Right now I’m using these components:
>>mosquito 1.2
>> Windows 7
>> Paho mqtt client java 0.4
>> Java 7, Spring 3.2.
 
Once the perisistence mqtt client gets disconnected (well I unplug my cable), then it throws an exception,
 
onnection lost (32109) - java.net.SocketTimeoutException: Read timed out
                at org.eclipse.paho.client.mqttv3.internal.CommsReceiver.run(CommsReceiver.java:138)
                at java.lang.Thread.run(Unknown Source)
Caused by: java.net.SocketTimeoutException: Read timed out
 
Later when I try to publish , 
 
com.lnt.ubiqrede.exception.UBIQRedeException: Error while sending Data, 
                at org.eclipse.paho.client.mqttv3.internal.ExceptionHelper.createMqttException(ExceptionHelper.java:27)
                at org.eclipse.paho.client.mqttv3.internal.ClientComms.sendNoWait(ClientComms.java:132)
                at org.eclipse.paho.client.mqttv3.MqttAsyncClient.publish(MqttAsyncClient.java:785)
 
 
Basicallt my doubt is if the mqtt client gets disconnected, does it tries to reconnect or we need to do it ourself. 
 
Regards,
Bharath.
