o
tag_id : ID of the tag (s ee tag’s ID specifications).
o
rssi : The detection tag’s signal RSSI I and Q measured values in dB
(optional variable present only if the RSSI information flag in
the RF parameters is active).
o
antenna : the detection antenna info (optional variable present
only if the reading antenna information flag in the general
parameters is active)
:
▪
0x01 -> Antenna 1.
▪
0x02 -> Antenna 2
o
direction : the gate crossing direction (optional variable present
only if ‘gate’ mode is active) :
▪
0x01 -> Crossing from input 1 to input 2.
▪
0x02 -> Crossing from input 2 to input 1.
o
timestamp : the detection timestamp. BCD coded with the following
format yyyyMMddhhmmss. In case of no RTC or RTC error this field
is filled with 0xFF bytes. (optional variable present only if the

• If configured and avaiable an host can wait for incoming ‘spontan e ous’
messages through Wieagand interface. The ‘spontaneous’ me ssage is sent
only once and no ACK/NAK reply message is implemented except of the
normal TCP handshake mechanism, see the protocol manual for details.
• If configured and avaiable an host can wait for incoming ‘spontaneous’
messages through CAN bus. The ‘spontaneous’ message is sent only once
and no ACK/NAK reply message is implemented except of the normal CAN
bus handshake mechanism, see the protocol manual for details.
• If configured and available an host can connect the reader on the
configured Bluetooth connection
and wait for ‘spontaneous’ messages. The
‘spontaneous’ message is sent only once and no ACK/NAK reply message
is implemented except of the normal Bluetooth handshake mechanism,
see the protocol manual for details.
In case of a ‘spontaneous’ message send error, due to a connection
or communication error, no further attempts will be made and the
tag will be discarded!
