Hello to everybody,
during these hours, I'm noticing another strange thing ...
In the Python script (which is attached to the previous message), I set the
parameters of the session and I pitch them to EMANE using the following
lines:
...
> values [names.index ('pathlossmode')] = 'freespace'
> modelClass = EmaneIeee80211abgModel
> session.emane.setconfig (wlan.objid, modelClass._name, values)
After that I launched the Python script from the GUI of CORE and after that
the network is shown on the canvas, I notice that if I open the
"ieee80211abg configuration " window of the wlan node all the parameters
are correctly set. Instead, the same parameters on the two MDRs are not
displayed correctly. I.e., in wlan node the pathloss mode is set to
"freespace" and in two MDRs it is set to "2ray". There are similar problems
with other parameters.
Is this a bug or is it a correct behavior?
Thank you very much,
