AttributeError: type object 'socket' has no attribute 'timeout'

Post by jeancf » Wed Jan 04, 2017 7:41 pm

I am running micropython 1.8.6 on a Wemos D1 mini v1.

I have an application that uses UDP sockets. It runs but I have a problem catching `timeout` exceptions. This code:

Code: Select all

from machine import UART
import socket

uart = UART(0, 115200)

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.settimeout(2.0)
s.bind(("", 9999))
try:
    s.receive(10)
except socket.timeout:
    uart.write("Exception caught\n")
throws:

Code: Select all

Traceback (most recent call last):
  File "main.py", line 12, in <module>
AttributeError: type object 'socket' has no attribute 'timeout'
Instead of catching the exception.

Am I doing something wrong?

No I guess, not. I had the same problem. Looks like socket.timeout is not implemented (or is not the correct exception that upython throws on timeout). I simply catch everything and that worked for me.

Code: Select all

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.settimeout(2.0)
s.bind(("", 9999))
try:
    s.receive(10)
except:
    uart.write("Exception caught\n")

Thanks for the workaround. I can use it for now. I will file a bug.
