Hi, HåkonAlseth

Thank you very much, the IO mouth interruption has been verified through

Kind regards. Peter.Min

Hi,

As mentioned, I tried the code on a board that I know that P0.15 is accessible with, and it worked at my end.

Are you certain that the button you have connected on this pin is active low?

Kind regards,

Håkon

I put it on my board and tested P.015, but I still couldn't get in.

The engineering routines I use are as follows

Hi,

As mentioned, P0.15 isn't routed to the pin header on nRF9160-DK, as shown here:

Kind regards,

I was testing this on a nRF9160-DK.

CTS has been changed by me to 8 feet.

The prj.conf configuration is as follows:

# BSD library
CONFIG_BSD_LIBRARY=y
CONFIG_BSD_LIBRARY_TRACE_ENABLED=n

I've modified this file to avoid serial impact:

D:\ncs\v1.2.0\zephyr\boards\arm\nrf9160_pca10090\nrf9160_pca10090_common.dts

devzone.nordicsemi.com/.../nrf9160_5F00_pca10090_5F00_common.rar

15 foot interrupts still cannot be detected after modifications such as above

Hi,

Are you testing this on a nRF9160-DK?

If yes, the GPIO P0.15 is connected to the UART1 interface (CTS), thus isn't routed to the pin header.

I tested your code isolated, on another board I have (added it to zephyr/samples/basic/button and compiled it), and I was able to get the pin toggling.

Since you are using this with asset_tracker, could it be that you have enabled CONFIG_BSD_LIBRARY_TRACE_ENABLED, which uses UART1 interface?

Kind regards,

Håkon
