Hi James,

I get similar results to the results I published while running a continuous
successful ping in Station Mode.

I also get similar results when I issue wifi.sta.disconnect() and it is
clear as the pings are not returned. I can not determine that after the
disconnect is issued that the radio is turned off.  My existing setup does
not enable me to read precise enough current values, but the needle on the
meter does not appear to shift.  It gives a slight flutter when I issue the
connect command.  I will modify the setup shortly to better read currents.

The tests I initially ran were in connected mode but I was not actively
pinging the device at the time.

Justin
