I am working on the Quectel MC-60 Module.
As per the reference document the power key is used to power on or off the MC-60 GSM module.
I want to use the power key function such that,
By holding the power key down (GND) the GSM module will be powered on.
By holding the power key up (VCC or 3V3) the GSM module will be powered off.
Is this possible to update the power key functionality as expected in the Open CPU SDK?
I don’t want to use the External Microcontroller to drive the MC-60.
MC-60 is powered by the LIPO battery & I need to be the MC-60 turned on as soon as the batter has greater than 3.3V. (i.e by default MC-60 in ON state as the supply meets the voltage & current ratings)
I need the External Reset Switch to Hard reset the MC-60 when needed.
In short, I need any pin (for me POWER KEY) that can drive the MC-60 module as ON when POWER KEY is grounded & OFF when it pulls to the high.
But if you see the Quectel documentation (MC60 Hardware Design: Section 3.7. Power-on/off Scenarios in All-in-one Solution) for the Power key function to turn on & off the module a specific clock pulse is required. (typically of 100mSec)
I want to change this function over the state of the POWER KEY to make it simple as the POWER key grounded GSM will turn on else turn off.
