vernemq compatibility

[njordr]

Hi.

Have you got on your roadmap the compatibility with vernemq?

I try your code (publisher) and it fails on connect in this assert (line 84):

assert resp[0] == 0x20 and resp[1] == 0x02

Thanks

Please read http://www.chiark.greenend.org.uk/~sgtatham/bugs.html and try again.

vernemq 0.14.1 umqtt.simple (lastest from github) 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 2016-11-06 20:46:13.121 [error] <0.583.0> Ranch listener {{0,0,0,0},1883} terminated with reason: {badmatch,<<0,4,77,81,84,84,4,2,0,0>>}

Please let me know if you need more details (apologize to not gave them before)

Did you try your set-up with mosquitto as the broker? The code above works for me, running the simple publish code with micropython unix, and the paho code with CPython unix.

And I tested the same thing but with vernemq as the broker. It also works.

Possibly the error is in the WiPy 2.0 firmware.

With mosquitto it works. I'll try to write to wipy guys

Thanks
