vincar commented 7 years ago

Hi, when I use the latest version of ruby-mqtt,it will print

mqtt-0.5.0/lib/mqtt/packet.rb:281:in `read': Connection reset by peer (Errno::ECONNRESET)

and Apollo print

java.lang.NullPointerException at org.apache.activemq.apollo.mqtt.MqttProtocolHandler.on_mqtt_connect(MqttProtocolHandler.java:443)

Hello,

I don't personally use Apache Apollo. Did it work in previous versions of ruby-mqtt?

The major change in 0.5.0 is that it now defaults to MQTT v3.1.1 (the OASIS Standard published in October 2014). You can go back to the old protocol version using:

MQTT::Client.connect('test.mosquitto.org', :version => '3.1.0')

See the release notes for more changes: https://github.com/njh/ruby-mqtt/releases/tag/v0.5.0

Thank you!@njh

Surprised/disappointed that there isn't a version of Apache Apollo that supports MQTT 3.1.1 - that is the only version that has been properly standardised.
