Power consumption of NRF52 GPIOTE->IN

Jorgewu

Hi all: I found this issue happen on NRF52 with SDK v11.0. Because I measured the current increased ~1mA after enable GPIOTE->IN, is there any solution can solve it?? Thanks...

    After fine tuning my codes the power is down to 1.97 mA in the conditions(The current is Same as the conditions of just execute the loop of __WFI(), in the main()) 1.Enable softdevice. 2. without advertising.. 3. My HW just connect G-sensors via I2C However it still cannot enter power off mode... My Sense pin is pin27 , here is the pin status before enter power_off and reset reason(UART is enabled to print message(pin30, 31 for CTS/RTS, and pin 29 for DTM enable )) NRF_GPIO->IN:0x80200000 Reset Reason:0x50005 Is any item needed be checked again?

    Thanks..
