The MQTT v3 spec has been updated to v3.1. The significant change is the
|
||
|
inclusion of the option to send a username and password as part of the connect
|
||
|
command. The new spec is available at
|
||
|
<http://www.ibm.com/developerworks/webservices/library/ws-mqtt/index.html>
|
||
|
and is a lot more readable and clear than the original.
|
||
|
|
||
|
Mosquitto will support the v3.1 spec in a future release, along with the
|
||
|
ability to control both broker and topic access by username. In the meantime,
|
||
|
if you need this functionality, the IBM proprietary [RSMB] broker may be
|
||
|
suitable for testing purposes. The RSMB package now also includes an MQTT
|
||
|
client library, a simple publish client and a simple subscribe client, just
|
||
|
like mosquitto. Be sure to check the license terms before using it!
