# 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.

/*
Basic ESP8266 MQTT example
This sketch demonstrates the capabilities of the pubsub library in combination
with the ESP8266 board/library.
It connects to an MQTT server then:
- publishes "hello world" to the topic "outTopic" every two seconds
- subscribes to the topic "inTopic", printing out any messages
it receives. NB - it assumes the received payloads are strings not binary
- If the first character of the topic "inTopic" is an 1, switch ON the ESP Led,
else switch it off
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"

# Arduino Client for MQTT Test Suite
This is a regression test suite for the `PubSubClient` library.
There are two parts:
- Tests that can be compiled and run on any machine
- Tests that build the example sketches using the Arduino IDE
It is a work-in-progress and is subject to complete refactoring as the whim takes
me.
## Local tests
These are a set of executables that can be run to test specific areas of functionality.
They do not require a real Arduino to be attached, nor the use of the Arduino IDE.
The tests include a set of mock files to stub out the parts of the Arduino environment the library
depends on.
### Dependencies
- g++
### Running
Build the tests using the provided `Makefile`:
$ make
This will create a set of executables in `./bin/`. Run each of these executables to test the corresponding functionality.
*Note:* the `connect_spec` and `keepalive_spec` tests involve testing keepalive timers so naturally take a few minutes to run through.
## Arduino tests
*Note:* INO Tool doesn't currently play nicely with Arduino 1.5. This has broken this test suite.
Without a suitable arduino plugged in, the test suite will only check the
example sketches compile cleanly against the library.
With an arduino plugged in, each sketch that has a corresponding python
test case is built, uploaded and then the tests run.
### Dependencies
- Python 2.7+
- [INO Tool](http://inotool.org/) - this provides command-line build/upload of Arduino sketches
### Running
The test suite _does not_ run an MQTT server - it is assumed to be running already.
$ python testsuite.py
A summary of activity is printed to the console. More comprehensive logs are written
to the `logs` directory.
### What it does
For each sketch in the library's `examples` directory, e.g. `mqtt_basic.ino`, the suite looks for a matching test case
`testcases/mqtt_basic.py`.
The test case must follow these conventions:
- sub-class `unittest.TestCase`
- provide the class methods `setUpClass` and `tearDownClass` (TODO: make this optional)
- all test method names begin with `test_`
The suite will call the `setUpClass` method _before_ uploading the sketch. This
allows any test setup to be performed before the sketch runs - such as connecting
a client and subscribing to topics.
### Settings
The file `testcases/settings.py` is used to config the test environment.
- `server_ip` - the IP address of the broker the client should connect to (the broker port is assumed to be 1883).
- `arduino_ip` - the IP address the arduino should use (when not testing DHCP).
Before each sketch is compiled, these values are automatically substituted in. To
do this, the suite looks for lines that _start_ with the following:
byte server[] = {
byte ip[] = {
and replaces them with the appropriate values.
