Thank you Vidar Berg You are correct. Everything is working as expected now with no changes to this code.

Thanks for confirming. I thought I had tried with SDK 2.5.x earlier. Anyway, it built successfully when I tried again, but P0.13 is toggled by the RTC event in my case. Could there maybe be a conflict with the pin assignments in your project?

Pin configuration:

GPIOTE out task:

RTC2 config

Test project:

I believe we are using SDK version 2.5.2, with Zephyr version 3.4.99. It does comp;ilke just fine for me.

Hello,

Which SDK version are you using? I couldn’t spot any obvious errors in the code you posted, so I tried building it myself. However, I couldn’t get it to compile because it's using an older version of the nrfx API.

Thanks,

Vidar
