RE: [weewx-user] Re: Exceptions attribute error - Interceptor driver for Acurite bridge

2018-05-28 Thread 'Scott Weis' via weewx-user 
I run weewx on a Raspberry Pi model B (512Mb ram and 700  
<https://en.wikipedia.org/wiki/Hertz> MHz single-core  
<https://en.wikipedia.org/wiki/ARM11> ARM1176JZF-S, running since 2013)  Since 
the Pi Zero has a 1 GHz single-core  <https://en.wikipedia.org/wiki/ARM11> 
ARM1176JZF-S and 512Mb Ram it should be fine.

Hi Mathew,

 

Thanks again. I'm not at a fluent in python. I've spent more time trying to get 
this running on Mac OS than it's worth. Going to order a Raspberry Pi 3 and try 
from there. So many more people running that, and support will be easier for 
everyone if I run into trouble.

 

I do have a RPi Zero W on hand. What your opinion on using that, would it be 
sufficient, or under powered for the task?

nope - you'll be better of working with the latest

 

are you certain that you installed the pylibpcap bindings properly?  did you 
test by starting a python shell and doing the imports directly?

Thanks so much for that helpful reply Matthew. I found the pylibpcap 
bindings here , 
but unfortunately I still get the same result. Tried rebooting for good 
measure, but no change. Tried uninstalling pypcap as well, but still no 
change in result.

douglas,

this looks like a pcap library issue.  i think there are two python 
bindings for pcap:  pypcap and pylibpcap.  apparently pylibpcap has the 
pcapObject, but pypcap does not.

https://stackoverflow.com/questions/2501138/module-object-has-no-attribute-pcapobject

when i did the development of weewx-interceptor, the 'pip install pypcap' 
gave me the pylibpcap bindings.  but more recently i have been using the 
debian-based python-libpcap package, which seems to have pylibpcap bindings 
as well.  if you did the 'pip install pypcap' you might have gotten the 
pypcap bindings.

so what do we do?

option 1: figure out how to install the pylibpcap bindings on your system. 
 you might be able to do this with 'pip install pylibpcap'

option 2: adjust the weewx-interceptor code so that it works with either 
pypcap or pylibpcap bindings.  i'm happy to support whichever pcap bindings 
are more prevalent/modern/available.  the APIs are not compatible, but they 
are used in only less than 10 lines of code.
