Bluetooth Shield affects AnalogPins

-

hi,

i'm trying measurement on photodiode both via usb , bluetooth.
the problem usb data way more accurate bluetooth data.

while usb data drifts between 3-4 values, bluetooth drifts between 6-7.

the problem seems shield, because when recive data both on usb & bluetooth simultaneously data same. without shield accuracy goes again.

anyone has idea what's problem or knows how fix it?

ciao
