Issue with vernemq mqtt broker

[alfheim]

Hi

I try to use vernemq with wipy.

vernemq 0.14.1
umqtt.simple (https://github.com/micropython/micropython-lib)
wipy 2 board

On the wipy board the following code

from umqtt.simple import MQTTClient


def main(server="192.168.1.150"):
    c = MQTTClient(b"ran", server)
    c.connect()
    c.publish(b"test/ran", b"hello")
    c.disconnect()


if __name__ == "__main__":
    main()

On the other side simple consumer in paho

import paho.mqtt.client as mqtt  # The callback for when the client receives a CONNACK response from the server.


def on_connect(client, userdata, rc):
    print("Connected with result code " + str(rc))
    # Subscribing in on_connect() means that if we lose the connection and
    # reconnect then subscriptions will be renewed.
    # client.subscribe("$SYS/#")
    client.subscribe('test/ran')


# The callback for when a PUBLISH message is received from the server.
def on_message(client, userdata, msg):
    print(msg.topic + " " + str(msg.payload))


client = mqtt.Client()
client.on_connect = on_connect
client.on_message = on_message
# client.username_pw_set('test01', password='test')

client.connect("192.168.1.150", 1883, 60)

# Blocking call that processes network traffic, dispatches callbacks and
# handles reconnecting.
# Other loop*() functions are available that give a threaded interface and a
# manual interface.
client.loop_forever()

When I run the publisher, this is the error on wipy:
Traceback (most recent call last):
File "", line 12, in
File "", line 6, in main
File "/flash/lib/umqtt/simple.py", line 84, in connect
IndexError: bytes index out of range

In the vernemq error log:
2016-11-06 20:46:13.121 [error] <0.583.0> CRASH REPORT Process <0.583.0> with 0 neighbours crashed with reason: no match of right hand value <<0,4,77,81,84,84,4,2,0,0>> in vmq_parser:parse/4 line 71

Is this "finalized" repo?
I go to this repo and see many not implemented code
"asyncio"
"calendar"
...

maybe you should ask repo admins about code?
