Configuration issue with rabbitMQ and sneakers

I have two applications sap1 and sap2 and i have been using rabbitMQ (bunny gem) for messaging, so that is working like from sap1 i will create the message and publish

sap1 (publisher app)

Gemfile

ruby 1.9.3
gem 'bunny', '~> 1.7', '>= 1.7.1'

publish.rb

def publish
    # Start a communication session with RabbitMQ
    connection = Bunny.new(:host => "123123", :vhost => "1231", :user => "123", :password => "Z7tN")
    connection.start

    # open a channel
    channel = connection.create_channel

    # declare a queue
    queue  = channel.queue("refresh-pos-menu-test", :durable => true)

    # publish a message to the default exchange which then gets routed to this queue
    values = { mac_id: 14123 }
    queue.publish(values.to_json)
    connection.close
end

sap2 (consumer app)

Gemfile

ruby 2
gem 'bunny'
gem 'sneakers'

config/initializers/sneakers.rb

require 'sneakers'
Sneakers.configure :connection => Bunny.new(:host => "123123", :vhost => "1231", :user => "123", :password => "Z7tN"), :timeout_job_after => 360

Rakefile

require 'sneakers/tasks'

app/workers/mac_worker.rb

class MacWorker
  include Sneakers::Worker
  from_queue "mac-test"

  def work(params)
     # Calling the function
  end
end

and in the console for listen doing this

 bundle exec rake sneakers:run

Here this is working, sometimes i am getting connection issue also, in the consumer app i don't want to use sneakers gem so instead i want to read message from queue with bunny and put it into sidekiq, also how to listen automatically in sidekiq?
