title: How to send RabbitMQ heartbeat frame using pika 1.2.0?
body: <p>I am using <code>pika.BlockingConnection</code>. I use <code>basic_publish</code> and <code>channel.consume</code> for publishing and consuming messages.</p>
  <p>Everything works well when <code>heartbeat</code> is set to <code>0</code> but when I set any value (60 for ex), RabbitMQ raises error: <code> missed heartbeats from client, timeout: 60s</code>. How do I send heartbeat frame?</p>
  <p>I use <code>pika==1.2.0</code> version.</p>
  <p>Update: is any additional info needed?</p>
