Well, still then you're relying on the fact that passive channels scans
will stick to each channel for ~110ms or so. This is true today, but
it's not really specified.

I don't think that using the scan command would be a big deal, but maybe
this 'measurement' behaviour should be explicitly enabled? Maybe other
devices even have to do something special to collect the data.
