This item was bought for battery use with deep sleep purposes. For doing so in ESP8266
reset pin must be connected to
Gnd pin in order to wake up. This board lacks a
reset on- board pin.
Since spec states it has a such capabilities - I wonder if someone has succeeded with putting it to sleep ( and wake it back on ).
PS - I know that on-chip
gpio16 can be soldered to on-chip
gnd - I'm hoping there is a more elegant, not soldering invloved, solution.
