1.9
|
||||||
|
* Do not split MQTT packets over multiple calls to _client->write()
|
||||||
|
* API change: All constructors now require an instance of Client
|
||||||
|
to be passed in.
|
||||||
|
* Fixed example to match 1.8 api changes - dpslwk
|
||||||
|
* Added username/password support - WilHall
|
||||||
|
* Added publish_P - publishes messages from PROGMEM - jobytaffey
|
||||||
|
|
||||||
|
1.8
|
||||||
|
* KeepAlive interval is configurable in PubSubClient.h
|
||||||
|
* Maximum packet size is configurable in PubSubClient.h
|
||||||
|
* API change: Return boolean rather than int from various functions
|
||||||
|
* API change: Length parameter in message callback changed
|
||||||
|
from int to unsigned int
|
||||||
|
* Various internal tidy-ups around types
|
||||||
|
1.7
|
||||||
|
* Improved keepalive handling
|
||||||
|
* Updated to the Arduino-1.0 API
|
||||||
1.6
|
1.6
|
||||||
* Added the ability to publish a retained message

Publishing in the callback
|

|
- connects to an MQTT server

|
- subscribes to the topic "inTopic"
|
||||||
|
- when a message is received, republishes it to "outTopic"
|
||||||
|
|

This example shows how to publish messages within the
|
||||||
|
callback function. The callback function header needs to
|
||||||
|
be declared before the PubSubClient constructor and the
|
||||||
|
actual callback defined afterwards.
|
||||||
|
This ensures the client reference in the callback function
|
||||||
|
is valid.
