POWER unexpected reset

[huaminhtuan]

Hi everyone,

I am developing a remote control using nRF52832 chip. My prototype is currently developed in PC10040 board. The IDE is Eclipse Oxygen, and the SDK is S132 v5.0.0.

Currently, I am trying to put the system in low power mode using POWER module. I can easily power off the system by setting the register NRF_POWER->SYSTEMOFF = 0x01;. The problem is when I try to wake up the chip by pressing a button, which is configured with SENSE_LOW mechanisim, the system is unexpectedly reset countinously. I don't know where is the reason.

Could you help me please? Thanks

Hi Sigurd, the question should be closed because I found the answer. The solution for my issue is disable all running peripherals and config an interrupt using GPIOTE instead of GPIO sensing level.
