Exmqttc

Elixir wrapper for the emqttc library.
emqttc must currently be installed manually as it is not available on hex (yet).
Installation
The package can be installed by adding exmqttc
and emqttc
to your list of dependencies in mix.exs
:
def deps do
[{:exmqttc, "~> 0.3"}, {:emqttc, github: "emqtt/emqttc"}]
end
Usage
Create a callback module:
defmodule MyClient do
require Logger
def init do
{:ok, []}
end
def handle_connect(state) do
Logger.debug "Connected"
{:ok, state}
end
def handle_disconnect(state) do
Logger.debug "Disconnected"
{:ok, state}
end
def handle_publish(topic, payload, state) do
Logger.debug "Message received on topic #{topic} with payload #{payload}"
{:ok, state}
end
end
You can keep your own state and return it just like with :gen_server
.
Start the MQTT connection process by calling start_link/3
:
{:ok, pid} = Exmqttc.start_link(MyClient, [], host: '127.0.0.1')
