GPIOTE consumption too high

[ting²]

Hi, My application uses the softdevice 110. Everytime, there is an event on my sensor. The sensor sends the event to my pin, which generates a gpiote interrupt . But, the consumption is too high. We have about 4mA/300µs. Is it normal? If not, how to solve this?

Thank you for your answer. Indeed ,setting the GPIOTE into PORT MODE , the consumption is reduced. But, I also need EVENT/TASK event for another pin. Is it possible to have the both modes ? I used app_gpiote.c to create my gpiote interrupt. I understood that in "app_gpiote' , the port mode is used. So why the consumption is so high? Or did I misunderstand something?

You can use both PORT event and configure gpiote for EVENTS/TASK, nrf_drv_gpiote.c uses both. if you are only using app_gpiote.c then it should be just the PORT mode,hence it should be less power. Can you readout the config registers of GPIOTE and see if they are having reset values?
