1.2.3.1 Buttons
The DLP NIRscan Nano EVM includes three buttons:
• Wake button:
– When the system is in standby, pressing the Wake button will wake the system from hibernation
mode.
– Upon wake up, the green LED will pulse on and off.
• Scan/Bluetooth button:
– When pressed and released, the system performs a scan. During a scan, the yellow LED is
illuminated and the lamps will turn on for the duration of the scan.
– When pressed, held for more than 3 seconds, and then released, the Bluetooth subsystem powers
up and advertises a connection. While a Bluetooth Low Energy connection is advertised, the blue
LED will turn on. When a Bluetooth Low Energy connection is active, the blue LED will pulse off
and on. The pulsing may coincide with the green LED or may pulse opposite to the green LED
pulses.
• Reset button:
– Pressing the Reset button will initiate a hardware reset of the NIRscan Nano system.
