Data Fields | |
char | struct_id [4] |
int | struct_version |
int | sendWhileDisconnected |
int | maxBufferedMessages |
int | MQTTVersion |
char struct_id[4] |
The eyecatcher for this structure. must be MQCO.
int struct_version |
The version number of this structure. Must be 0 or 1 0 means no MQTTVersion
int sendWhileDisconnected |
Whether to allow messages to be sent when the client library is not connected.
int maxBufferedMessages |
the maximum number of messages allowed to be buffered while not connected.
int MQTTVersion |
Whether the MQTT version is 3.1, 3.1.1, or 5. To use V5, this must be set. MQTT V5 has to be chosen here, because during the create call the message persistence is initialized, and we want to know whether the format of any persisted messages is appropriate for the MQTT version we are going to connect with. Selecting 3.1 or 3.1.1 and attempting to read 5.0 persisted messages will result in an error on create.
