Get hub address...

[vascolp]

Hi,

Is there a simple way to get the mac address on a TechnicHub or CityHub object?

Thanks and Regards,

I mean, inside python code running on it....

No there isn't currently a way to do this. Why do you need the address?

[vascolp]

Well...
I want a way to store some parameters in the Hub, when I turn it off, so that I have the same configuration when turned on.
One good place could be the name of the Hub, but there is no way to set it yet...
However, I noticed I could use the Remote name property, because I can set it.... and it would be nice to have it configured for a given hub only.... the mac address is a good unique id for the hub.
Thanks for your fast answer!

You can save a program with parameters on the hub.

For example, save this program on the hub:

my_data = "Test"
more_data = (1, 2, 3)

Now you can run a new program that uses this information:

from main import my_data, more_data

print(my_data)
print(more_data)

Hmmmm :-)
Is that read-write? Can I change them? For instance
my_data="1234"
and get 1234 next time I run?

No, but that wouldn't be the case for the MAC address either.

These hubs do not really have storage space for user data. There's only the firmware itself.

I know MAC is read-only, and MAC was indid was my first question...
What I would like is to be able to save a small amout of data on the hub, persistently. The 14 charecters from the name would be enough.
Currently name on the hub is not read-write , so I will use name from the remote, which is writable and persistent even if you remove batteries.
I just thought I could tie that config in the remote with the given hub by storing hub MAC address on the remote also.....
but I live without it. In fact beeing able to change the Hub name is much more interesting than getting its MAC address :-)
Thank you!
