luamqtt examples

The simplest example are in examples/simple.lua file.

It's performing all basic MQTT actions:

  1. connecting to broker
  2. subscribing to topic
  3. publishing message after subscription creation
  4. receiving self-published message
  5. disconnecting from MQTT broker

Here is an expected output of such script:

created MQTT client     mqtt.client{id="luamqtt-v2-0-0-5807dc7"}
running ioloop for it
connected:      CONNACK{rc=0, sp=false, type=2}
subscribed:     SUBACK{rc={1}, packet_id=1, type=9}
publishing test message "hello" to "luamqtt/simpletest" topic...
received:       PUBLISH{payload="hello", topic="luamqtt/simpletest", dup=false, retain=false, qos=1, packet_id=1, type=3}
disconnecting...
done, ioloop is stopped

For other examples please see examples/last-will/ folder.

Also there is a MQTT client tests in tests/spec/mqtt-client.lua file, which also may be a good example.
