and “s901” indicates the firmware revision.
7.3.3 kSetDataComponents (frame ID 3
d
)
This frame defines what data is output when kGetData is sent. Table 7-3 summarizes the
various data components and more detail follows this table. Note that this is not a query
for the device's model type and software revision (see kGetModInfo). The first byte of
the payload indicates the number of data components followed by the data component
IDs. Note that the sequence of the data components defined by kSetDataComponents
will match the output sequence of kGetDataResp.
Example: To query for heading and pitch, the payload should contain:
When querying for data (kGetData frame), the sequence of the data component output
follows the sequence of the data component IDs as set in this frame.
