NFC SETTINGS SPECIFICATIONS
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: See the table below for all possible settings:
{key1}:{value1}
{key2}:{value2}
