GPIO interrupts not firing on NRF52840

Hello all!

I am using mbed to develop firmware for the NRF52840 MCU. I am currently using the NRF52840_DK target from target.json.

The problem I’m having is with GPIO interrupts: they work fine before I initialize the BLE stack but, after initializing the it (by getting the instance of the BLE class), the GPIO interrupts stop firing. The Timeout or Timer interrupts seem to keep working, it’s just GPIO apparently.

Any ideas?

Thank you,
