NFC settings specification
Settings on all Elsys LoRa sensors are stored on the embedded NFC chip which is a NFC Forum Type 4 tag with a NDEF text entry. Use our Android application or any other NFC application to read and write settings from the sensors.
The settings use the following format:
{key1}:{value1}
{key2}:{value2}
...
See the table below for all possible settings:
