GPIOTE consuming high current after first press of a button

Hi,

Sorry about the delay. If you want your device to go to sleep you can see how we do this in the examples in the SDK.

Any news? The device does not seem to sleep after button press. This is why current is high I believe. What am I missing to get this device to sleep?

it is clear that the device is not going back to sleep after woken up by the first button press. What should I do to make it go back to sleep on every press???

I just tested putting an external press button with a 10K resistor and removed the line :

in_config.pull = NRF_GPIO_PIN_PULLUP;

same thing. No matter what is done, on first press current goes high and stays high. I also tried to disable the pin and enable back on the in_pin_handler function. Nothing. Then, I tried to for the press button pin low in case it was sitting high for some reason. Nothing.

I tried with all of the SDKs current and old available on the website. Same problem on all.
To summarize:
- After first press, consumption goes high as seen above. Won't go down anymore

- When debugging, notice that the in_pin_handler is called twice on every button press

Hi.

Thanks for the information.

I'll test this and try reproducing it on my side. Are you using the latest nRF5 SDK (currently v.15.3.0)?

Best regards,

btw, I tested 2 different DKs with the same results. At one rare point, it actually temporarily spiked up the current when I pressed the button and went back to the original state. But that only happened like twice. The rest of the time, no matter how many times I restarted the DK it would spike up on the first button press. And then stays at 200+uA from there

Hi.

Could you tell me which DK you are working with, so that I can test this myself?

Also; are you seeing the high current consumption on a single button press (press and release) or are you holding the button down?

Best regards,

I dug a bit further and found ran the debugger. Found out that the in_pin_handler is being called twice on every key press. I wonder if this is causing high consumption. Why would the code above call in_pin_handler twice on the same button press?

could it be that

 in_config.pull = NRF_GPIO_PIN_PULLUP;

on the code is not working? therefore the pin is floating?
