# Description Pressing `Ctrl-C` to interrupt `time.sleep()` will cause `time.sleep()` to instantaneously return on NRF until the board is reset. # Steps to reproduce In the REPL, run: ```python import time time.sleep(100) ``` While it's sleeping, press Ctrl-C. The REPL will come back. Then run: ```python time.sleep(100) ``` The REPL will return instantly. # Workaround Performing a soft- or hard-reboot re-initializes the sleep timer and gets it working again.
