We haven’t heard of that client. What’s in RabbitMQ log files?

We’d recommend using Paho Java, I believe it is Android-compatible.

Please also check RabbitMQ log files, in particular SASL.

Take a look at http://www.rabbitmq.com/relocate.html.

File names will be rabbit@….log and rabbit@…-sasl.log. We’d appreciate if you
could post their contents (via gist.github.com, for example). Feel free to edit out hostnames
and IPs .

What’s in the regular log? Also, if you post something to gist.github.com, others
need a link in order to see it ;)

Excuse me i think i posted link.now I saw rabbit log and i post it in this link "https://gist.github.com/anonymous/616e7cc2bb8bd7ab59a0" and i post sasl log in this link https://gist.github.com/anonymous/320f5867c03e619c8f66. I post log file because today logs 12-october were in this file.

See the first couple of paragraphs on http://www.rabbitmq.com/access-control.html.

Note that we *highly* recommend creating a separate user with a strong password
for production environments.

Now I check your recommended link http://www.rabbitmq.com/access-control.html but I can't find out this thing, that , when I want to connect Mqtt to broker, should android client post this particular user pass to broker? because i use WMQTT i only use this code to connect  mqttClient.connect(generateClientId(), cleanStart, keepAliveSeconds); and I dont't know how send user pass

Yes, you need to create a user, give it access to the vhost used by MQTT ("/" by default)
and configure the client to use that user.

However exactly that's done in WMQTT, I don't know. It should be something straightforward,
please take a look at the API of that library.

Ok, if i find out right, you mean this library may send specific user and pass and i should read wmqtt docs to find this user and make like that, in rabbitMqtt server.am i right?

MQTT is an interesting (to put this politely) protocol where authentication is optional,
so RabbitMQ has default credentials used for MQTT connections. Those can be configured
in RabbitMQ config file.

Yes, I was suggesting finding a way to specify credentials in WMQTT.

No worries, it wasn't difficult at all communicating with you.

If you have further RabbitMQ (or even MQTT) questions, don't hesitate to post
them to this list (as new topics, please) .
