BLUEBOX will hold onto a maximum of 10 tags when configured
to use the ‘spontaneous’ message. Once the 10 tag limit is reached,
the new tags will be discarded!
In ‘continuous’ mode the BLUEBOX can be configured to automatically connect
to a data acquiring TCP server (optionally with HTTP POST messages).
• If configured and available an host can wait for an incoming TCP
connection. On a succesful connection there is a fixed inactivity timeout of
120 seconds, the
BLUEBOX first sends its serial number and then waits
for incoming commands:
SOH <add h> <add l> STX <sn 1 h> <sn 1 l> ... <sn i h> <sn i l>
… <sn 6 h> <sn 6 l> ETX <bcc> CR
Where <sn 1 h> < sn 1 l> … <sn 6 h> <sn 6 l> is the serial number of the
device, it is a numeric code constituted by 12 digits, the bytes of the SN
are BCD-coded and so every byte encodes 2 digits (see the protocol
manual for details).
• If configured and available an host can wait for incoming HTTP POST to
receive records messages. An ACK/NAK reply is implemented through the
reception of the HTTP status OK message and in case of success the record
is dequed from the reacords database. On a succesful connection there is
a fixed inactivity timeout of 120 seconds.
These are the POST variables sent by BLUEBOX :
o
reader_sn : the BLUEBOX serial number.
o
mac_address : the BLUEBOX MAC address.
o
ip_address : the BLUEBOX IP address.
o
tag_type : the transponder type
(optional variable present only if
the tag type information flag in the general parameters is active) :
▪
0x02: ISO 18000-63
29
(EPC Class-1 Gen-2).
o
tag_id : ID of the tag (see 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).
29 ISO 18000-6C became ISO 18000-63 in 2012 due to ISO naming rules that do not allow letters in standards names.
