autonomy, it is preferable to only bring the smartphone close to the NFC antenna of the
COMFORT product when performing a read/write operation. Once the read/write operation
is complete, remember to move the smartphone away from the NFC antenna of the
product.
NOTE 2
The sensor is protected against unauthorized external access by an NFC security key
consisting of 8 alphanumeric characters. Therefore, only authorized individuals can modify
the sensor's configuration through this interface.
The NFC security key of the sensor can be changed by the user after the initial connection.
If the security key of a sensor is changed, the new key must also be entered in the
application settings to allow it to continue communicating with the sensor.
