Analog RefernceReference (AREF) pin on Arduino MKR1000 not working?

Has anyone successfully used the AREF pin on MKR1000?

I'm trying to use an EXTERNAL voltage reference (I need 1.5V instead of the default 5V) with:

analogReference(EXTERNAL)

butBut when I compile I receive the following error message:

MKR_001:161: error: invalid conversion from 'int' to 'eAnalogReference {aka _eAnalogReference}' [-fpermissive]

In the documentation (for analogReference) I found the following:

DEFAULT: the default analog reference of 5 volts (on 5V Arduino boards) or 3.3 volts (on 3.3V Arduino boards)
INTERNAL: an built-in reference, equal to 1.1 volts on the ATmega168 or ATmega328 and 2.56 volts on the ATmega8 (not available on the Arduino Mega)
INTERNAL1V1: a built-in 1.1V reference (Arduino Mega only)
INTERNAL2V56: a built-in 2.56V reference (Arduino Mega only)
EXTERNAL: the voltage applied to the AREF pin (0 to 5V only) is used as the reference.

Thanks, Corrado
