#include <MQTTAsync.h>
◆ struct_id
The eyecatcher for this structure. must be MQCO.
◆ struct_version
The version number of this structure. Must be 0, 1, 2 or 3 0 means no MQTTVersion 1 means no allowDisconnectedSendAtAnyTime, deleteOldestMessages, restoreMessages 2 means no persistQoS0
◆ sendWhileDisconnected
int sendWhileDisconnected |
Whether to allow messages to be sent when the client library is not connected.
◆ maxBufferedMessages
The maximum number of messages allowed to be buffered. This is intended to be used to limit the number of messages queued while the client is not connected. It also applies when the client is connected, however, so has to be greater than 0.
◆ 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.
◆ allowDisconnectedSendAtAnyTime
int allowDisconnectedSendAtAnyTime |
Allow sending of messages while disconnected before a first successful connect.
◆ deleteOldestMessages
◆ restoreMessages
◆ persistQoS0
