Issue with ble_app_uart example

Hello Nordic Team,

I have loaded the ble_app_uart example on my custom hardware. There is a button connected to P0.13. When that button is pressed I receive a NRF_BREAKPOINT_COND.

Any idea why this is occurring? I haven't set any GPIOTE init commands myself..

When connected to a phone and a button is pressed, the error does not occur. This is very odd and would like an explanation for this. Thank you
