Data format in UHF applications
The UHF read data is formatted by means of a header. The header has the following structure:
Type Name Meaning
uint8_t Size Data size
uint8_t Block type 1: UID/EPC/RSSI etc.
2: Read data
Other values : reserved
uint8_t Data [size] EPC/RSSI etc. or read data
The size of EPC/RSSI etc. depends on the settings of the reader.
Example: UHF read data (header and EPC, grouping deactivated)
Type Name Meaning
uint8_t Size 12
uint8_t Block type 1
uint8_t Data [14] uint8_t EPC [12]
Example: UHF read data (header and EPC, grouping activated)
Type Name Meaning
uint8_t Size 14
uint8_t Block type 1
uint8_t Data [14] uint8_t EPC [12]
Uint16_t Number of read operations (LSB Ò
MSB) [2]
Example: UHF read data (header, EPC, grouping with RSSI, socket, time, phase activated)
Type Name Meaning
uint8_t Size 24
uint8_t Block type 1
uint8_t Data [24] uint8_t EPC [12]
uint16_t RSSI (LSB Ò MSB)
uint16_t Slot (LSB Ò MSB)
uint32_t Time (LSB Ò MSB)
uint16_t Phase (LSB Ò MSB)
uint16_t Number of read operations (LSB Ò
MSB)
