If you're configuring ESPTerm via a smartphone, or were connected
from another external network, your device may lose connection and
this progress indicator won't work. Please wait a while (~ 15 seconds),
then check if the connection succeeded.</p>
<p>
To force enable the built-in AP, hold the BOOT button until the blue LED
starts flashing. Hold the button longer (until the LED flashes rapidly)
for a "factory reset".</p>
