ruby-em-mqtt

This gem adds MQTT (Message Queue Telemetry Transport) protocol support to EventMachine, an event-processing library for Ruby.

Installing

You may get the latest stable version from rubygems.org:

$ gem install em-mqtt

It depends upon the mqtt gem to perform packet parsing and serialising.

# Publish example

  c = ClientConnection.connect('test.mosquitto.org')
  EventMachine::PeriodicTimer.new(1.0) do
    puts "-- Publishing time"
    c.publish('test', "The time is #{Time.now}")
  end
end

# Subscribe example
