# Arduino Client for MQTT
|
||||
|
||||
This library provides a client for doing simple publish/subscribe messaging with
|
||||
a server that supports MQTT.
|
||||
|
||||
## Examples
|
||||
|
||||
The library comes with a number of example sketches. See File > Examples > PubSubClient
|
||||
within the Arduino application.
|
||||
|
||||
Full API documentation is available here: https://pubsubclient.knolleary.net
|
||||
|
||||
## Limitations
|
||||
|
||||
- It can only publish QoS 0 messages. It can subscribe at QoS 0 or QoS 1.
|
||||
- The maximum message size, including header, is **128 bytes** by default. This
|
||||
is configurable via `MQTT_MAX_PACKET_SIZE` in `PubSubClient.h`.
|
||||
- The keepalive interval is set to 15 seconds by default. This is configurable
|
||||
via `MQTT_KEEPALIVE` in `PubSubClient.h`.
|
||||
- The client uses MQTT 3.1.1 by default. It can be changed to use MQTT 3.1 by
|
||||
changing value of `MQTT_VERSION` in `PubSubClient.h`.
|
||||
|
||||
|
||||
## Compatible Hardware
|
||||
|
||||
The library uses the Arduino Ethernet Client api for interacting with the
|
||||
underlying network hardware. This means it Just Works with a growing number of
|
||||
boards and shields, including:
|
||||
|
||||
- Arduino Ethernet
|
||||
- Arduino Ethernet Shield
|
||||
- Arduino YUN – use the included `YunClient` in place of `EthernetClient`, and
|
||||
be sure to do a `Bridge.begin()` first
|
||||
- Arduino WiFi Shield - if you want to send packets > 90 bytes with this shield,
|
||||
enable the `MQTT_MAX_TRANSFER_SIZE` define in `PubSubClient.h`.
|
||||
- Sparkfun WiFly Shield – [library](https://github.com/dpslwk/WiFly)
|
||||
- TI CC3000 WiFi - [library](https://github.com/sparkfun/SFE_CC3000_Library)
|
||||
- Intel Galileo/Edison
|
||||
- ESP8266
|
||||
- ESP32
|
||||
|
||||
The library cannot currently be used with hardware based on the ENC28J60 chip –
|
||||
such as the Nanode or the Nuelectronics Ethernet Shield. For those, there is an
|
||||
[alternative library](https://github.com/njh/NanodeMQTT) available.

|
||||
- publishes "hello world" to the topic "outTopic"
|
||||
- subscribes to the topic "greenBottles/#", printing out any messages
|
||||
it receives. NB - it assumes the received payloads are strings not binary
|
||||
- If the sub-topic is a number, it publishes a "greenBottles/lyrics" message
|
||||
with a payload consisting of the lyrics to "10 green bottles", replacing
|
||||
10 with the number given in the sub-topic.
|
||||
|
||||
It will reconnect to the server if the connection is lost using a blocking
|
||||
reconnect function. See the 'mqtt_reconnect_nonblocking' example for how to
|
||||
achieve the same result without blocking the main loop.
|
||||
|
||||
To install the ESP8266 board, (using Arduino 1.6.4+):
|
||||
- Add the following 3rd party board manager under "File -> Preferences -> Additional Boards Manager URLs":
|
||||
http://arduino.esp8266.com/stable/package_esp8266com_index.json
|
||||
- Open the "Tools -> Board -> Board Manager" and click install for the ESP8266"
|
||||
- Select your ESP8266 in "Tools -> Board"
