Subject: [OASIS Issue Tracker] Commented: (MQTT-39) CONNACK return code references are inconsistent
[ http://tools.oasis-open.org/issues/browse/MQTT-39?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34019#action_34019 ]
Rahul Gupta commented on MQTT-39:
---------------------------------
Changes made in WD-06
-----------------------------------
line 508 - The server MUST respond to the CONNECT packet with a CONNACK return code 0x01 (unacceptable protocol level) and then disconnect client if the version number is higher than the protocol version that it supports.
line 709 - the server MUST respond to the CONNECT packet with a CONNACK return code 0x02 (Identifier rejected) and then terminate the TCP/IP connection if the unique client identifier is not between 1 and 23 characters in length.
In the current specification, document does not have examples of CONNACK return codes 0x03, 0x04 and 0x05.

> Key: MQTT-39
> URL: http://tools.oasis-open.org/issues/browse/MQTT-39
> Project: OASIS Message Queuing Telemetry Transport (MQTT) TC
> Issue Type: Improvement
> Components: edits
> Affects Versions: 3.1.1
> Reporter: Richard Coppen
> Fix For: 3.1.1

>
> The WD04 spec contains inconsistent references to CONNACK return codes
> Line 537 uses a HEX reference to a return code "CONNACK with return code 0x01"
> Lines 678 and 754 refer to "return code 2" (from the table on line 752) and repeat the meaning "Identifier Rejected"
> I think there is value to keeping the enumerated table for reference (reserving 6-255), although I can't see reference to the other return codes listed
> The spec should use consistent terminology for referencing return codes
