some concern about the new version

[brianping7]

Hi,

just saw the new version, why we try to get the device id and serial no every time? is it because it will change? i thought config it will be nice. reduce the network traffic

It's because we don't know what's "device id" nor "serial" for real. To my understanding some people have their robots with the same "device id" as I do, meaning that it's possible to detect them nicely, but some others do not (different hardware/firmware?).

In order to make it easy for people to try the lib & script out it's easier to force a hello packet during the initial connection. This could be optimized to avoid sending the discovery and to reduce the network traffic, but currently I doubt it's worth it.

For users of the library part it's possible to just use the context manager to execute multiple commands without requiring separate discovery calls:

with Vacuum('123.123.123.123') as v:
    if v.status() == 12: # error
        v.home()  # return home

sure, thanks for the explanation. :)
