Steps for using nRF Connect App

• You will have to go to the Bootloader mode. Open the SensePi unit and disconnect the power connector.
  Now keep the switch pressed and connect the power connector. You will see the LED blinking in a Green-Red pattern.
  You are in Bootloader mode now.

• Now select the "Distribution packet (ZIP)" option.
• Browse to the location where you have the "SensePir_xxx_yyy.zip" file. Select the file and wait till the firmware is updated.
• The SensePi unit will now go to "Sensing Mode" after this.
