Power consumption of NRF52 GPIOTE->IN

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...

  • If you use IN event (high_acc = true) on nRF51 you will get around 800-900 uA. This is because the IN event on nRF51 request the HFCLK and 1V2 regulator as seen in the Product Specification part 8.3. If you use PORT event the current draw should be reduced to almost zero. This is done by setting it to false.

    On nRF52 this is different. IN event on nRF52 should not result in higher current draw.
