My question is about the change the hard switch as the reference design to the soft switch.
Now my setup: DA14583 IoT Sensor.
We used a hard switch as the reference design, which means that every time we cut off the power, the whole system stop working.
We would like to change the hard switch (connected with VBAT3V) to the soft switch, which means that the MCU is still working.
For example, we would like to connect a soft switch at P2_1 to control whether Bluetooth starts working or not. How can we do that?
Could you please give me some suggestion? Thanks!
