OSError: 23

  • Hello , I'm trying to run an MQTT EXAMPLE , but i always get that error :
    Traceback (most recent call last):
    File "<stdin>", line 19, in <module>
    File "mqtt.py", line 55, in connect
    OSError: 23

    any issue ??

    I think this may be an error associated with an accumulating number of open sockets.
    I got the same OSerror: 23 after running the MQTT example for the 8th time and beyond. A soft reset does not clear this, but powering on/off does clear it - and it works again, at least for the first 7 times.
    I fixed this problem by adding one line at the very end of the MQTT example.

    Hi @YazIdo,

    Which library are you using for the MQTT example? The one current on the docs is out of date and will be updated in the next push of updates!
