Sensor behavior
NFC Read / Write
1.
When reading or writing NFC
configuration data to the sensor, it starts
a timer and delays its action 5 seconds.
2.
After the delay, the sensor determines if
the NFC data has changed or not. If the
data has changed, the sensor reboots
and starts from power-up.
3.
Write your settings in the application
and then locate the NFC antenna of the
phone and sensor. Keep the two
devices close and don
’
t move them to
get the best connectivity as possible
when writing or reading data to the
sensor. Bad connection can be caused
by long distance, wrong location, or
rapid movement.
4.
When you have written data to the sensor, let the sensor reboot and restart
before trying to write again.
You should always validate your settings by reading the NFC data after the
sensor has restarted.
