  • Is LED-port defineable?

    Can the LED-port be defined (for 20737) when using bleprofile_LEDBlink() ?   Our board has the LED connected to P27.   The same question arrises for the button port.

  • Can't input pin be read that is also used as interrupt?

    An input port of a 20737 is defined as pull-up and interrupt (for a button). Reading the input always returns the same value no matter whether the pin is connected to ground or not. When not registering the interrupt...
