XBee ADC is always 03FF


I am using XBee 1 and trying to send an analog value. I have DIO4 set to ADC and ranged the input from 0 to 3 V. The received analog value is always 0x03FF (1023). Can you help to figure out why this is happening?

Thank you,

Try connecting VREF to VCC.

Thank you for pointing that out. The issue is solved.
