MQTT lib references? enable TLS for use with AWS

[admin]

You have disconnect on first publish, remove this code.

Code:

client.ON_PUBLISH = function()
  client:disconnect()
end

Also, try replacing the loop part to log the result:

Code:

while true do
  res, err = client:loop()
  if not res then
    log('mqtt error', err)
    os.sleep(1)
  end
end
