Force network.WLAN module to disconnect?

How to force network.WLAN module to disconnect?

Code: Select all

    # Client/Station Mode...
    theInterface=network.WLAN(network.STA_IF)
    if theInterface is None:
        #
        raise Exception('No Network?')
    # Over kill?
    theInterface.active(True)
    theNetworks=theInterface.scan()
    
    theInterface.disconnect()
    theInterface.active(False)
    

The last line in the code example, does not seem to work. If watch the connection it remains. The documentation states that the link state should change to 'down' if False is passed. But that does not seem to be working. This a bug?

You don't have any "connection", as you never call wlan.connect(). Where do you see that the interface is still active ?

If you set active to true, the link state is up, right? That means the interface is visible to the network. Link state on, will be sniffed out if searched for. Connect is higher in the OSI/ISO stack true, but I recall at work our security team could find devices by link state alone, since the connecting switch or router could 'see' link state of an end-node device. Is there something about link state, that is different with the specific driver used via network.WLAN?

Forgot to mention... when I did set to False, and watched my router, finally the device dropped of the connection list, so not sure if my router is just slow to show change of state, or what.

I don't believe there is any requirement for network.WLAN to inform the router it's going away. You should see similar behaviour if you just unplugged the device.

Yeah, it may just be the router is doing a very low level state check,, or gives up on port that has gone inactive.
