Python MQTT: TypeError: coercing to Unicode: need string or buffer, bool found
- by user2923860
When my python code tries to connect to the MQTT broker it gives me this Type Error:
Update- I added the Complete Error
Traceback (most recent call last):
File "test.py", line 20, in <module>
mqttc.connect(broker, 1883, 60, True)
File "/usr/local/lib/python2.7/dist-packages/mosquitto.py", line 563, in connect
return self.reconnect()
File "/usr/local/lib/python2.7/dist-packages/mosquitto.py", line 632, in reconnect
self._sock = socket.create_connection((self._host, self._port), source_address=(self._bind_address, 0))

sock.bind(source_address)

TypeError: coercing to Unicode: need string or buffer, bool found
The code of the python file is:
#! /usr/bin/python
import mosquitto
broker = "localhost"
#define what happens after connection
def on_connect(rc):
print "Connected"
#On recipt of a message do action
def on_message(msg):
n = msg.payload
t = msg.topic
if t == "/test/topic":
if n == "test":
print "test message received"
# create broker
mqttc = mosquitto.Mosquitto("python_sub")
#define callbacks
mqttc.on_message = on_message
mqttc.on_connect = on_connect
#connect
mqttc.connect(broker, 1883, 60, True)
#Subscribe to topic
mqttc.subscribe("/test/topic", 2)
#keep connected
while mqttc.loop() == 0:
pass
I have no idea why its giving me this it work 2 days ago.
