yeah - often HIGH works fine - just if you need to call the softdevice back you have to lower it, or use the scheduler. I've found generally LOW Is good enough, chip's not that busy.

Thank you very much! GPIOTE IRQ priority was defined in the nrf_drv_config.h file that I copied from SDK exemple project.

Usual problem - calling softdevice functions from an interrupt context with higher priority than the SVC call. I'll assume that your GPIOTE IRQ priority is APP_PRIORITY_HIGH, if you want to call softdevice functions from it, it needs to be LOW, or you need to use the scheduler.

And the app isn't "freezed", it's in the hardfault handler, hitting break in the debugger should show you that.
