I'm doing a headless setup, where we use the Pis in field work (tracking movement of seals via camera in the Cape Cod area), and so we can only monitor it headless, without a separate display (to save on power).
In order to have the Pis get time, I need them to connect to my colleague's iPhones (which are operating as hotspots), and use ntpd to get time from the internet.
However, I haven't yet figured out what the command is to query the WiFi network name, to confirm that it is connected to the right network - is there one?
