Is the power button on the MiFi connected to a GPIO, or it is hardwired into something else on the board that is not accessible/usable from software?
Just wondering if we can re-purpose the button to trigger a script when the unit is running. No battery on this MiFi, so otherwise the button is pretty pointless.
It 's hardwired , because you can’t add the battery to make the mifi working with battery . there are two hardware design.
Awww shucks, okay no worries we’ll just have to wire up an external push button to another one of the GPIO lines then.
The button is actually connected to to charger chip, not the SoC.
