Data Information​

Service Data vs Manufacturer Specific Data​

Starting from firmware version 2.0.0, it is possible to send data via Manufacturer Specific Data by enabling the Mfr. Data Enable parameter in the NFC configuration.

ELA Innovation Company Identifier (CIN): 0x0757

Scan Response Frame​

Certain formats allow sending a "Scan Response" frame containing additional information (tag name, battery, etc.).
