Detailed Description

A class to represent a read of an RFID tag. Provides access to the TMR_TRD_METADATA_FLAG_FREQUENCY tag structure and the metadata of the read event, such as the time of the read, the antenna that read the tag, and the number of times the tag was seen by the air protocol.

TMR_Reader* TMR_TagReadData::reader

Reader instance, to keep track of tag reads

TMR_uint8List TMR_TagReadData::reservedMemData

Read RESERVED bank data bytes

int32_t TMR_TagReadData::rssi

Strength of the signal received from the tag

TMR_TagData TMR_TagReadData::tag

The tag that was read

TMR_uint8List TMR_TagReadData::tidMemData

Read TID bank data bytes

uint32_t TMR_TagReadData::timestampHigh

Absolute time of the read (32 most-significant bits), in milliseconds since 1/1/1970 UTC

uint32_t TMR_TagReadData::timestampLow

Absolute time of the read (32 least-significant bits), in milliseconds since 1/1/1970 UTC

TMR_uint8List TMR_TagReadData::userMemData
