007 protocol (continued)
Command identifier 'w': Write data carrier, bulk
Write user data to several data carriers that are located in
the detection range of the specified antenna. With the
, either all data carriers in the detection
caRRieR Selection
range can be written to or only a subset previously
selected with the Select command. The number of data
carriers found and successfully written is returned.
The memory area to be written is specified via
and
addReSS numBeR of ByteS
data, the data is transmitted in fragmented form in one or
more packets, with each transmitted packet
acknowledged with a status message.
The following boundary conditions apply to the transfer:
– Maximum amount of data: 999999 bytes/data carrier
– Maximum number of data carriers: 999
