Hi,

When all four LEDs on your board turn on it is usually an indication that one of your functions has returned an error code that is checked by this macro: APP_ERROR_CHECK(err_code);

Often times that macro turns on all LEDs to indicate that something went wrong and if you debug like explained here you might get a clue of why and where you have a problem. Can you try this?
