What I've understood is that the ADC channel for reading Vdd can't be
used when in station mode connected to an access point.  So you either
read it before you connect, or you disconnect, by either calling the
disconnect function or changing mode to softap.

I've actually not seen any evidence that the external ADC channel is
also affected.  People might be conflating the two.  I'm interested in
your test results once you get to that.

Might be worth monitoring current to the ESP8266 to figure out for
sure if the radio is off.

Also use other means to verify disconnect, such as a ping from a host
on the network you joined.
