Command 0x10 - Send Big Block Data to Device
This command is used to provide data for several general commands and input reports (listed in
) in 60-byte increments. If the data size is greater than 60 bytes, the data must be split into several
smaller blocks, each containing a maximum of 60 bytes. Two data formats are used in connection with
this command: The first packet (block 0, see
) signals the start of a new data set and specifies
the complete total length of the data; subsequent packets (blocks 1 through n, see
) transmit the
actual data to a predefined buffer within the device. For more information about big blocks and TLV
format, see section
4.1 About Big Block Data and TLV Format
If an error occurs, the device terminates the command and reports the error in ACKSTS of
. For a full list of error codes, see
If no error occurs, the device stores the uploaded data in a local staging buffer for use by a subsequent
command, and the host must call that command to direct the device to consume the uploaded data.
