    Control Commands
    5.1
    Introduction
    The QT1111 control commands are those commands that affect the device operation.
    The control commands are listed in Table 5-1 and are described individually in the following
    sections.
    Note:
    Commands are implemented immediately upon reception, so a suitable delay is
    required for the operation to be completed before communications can be
    re-established.
    5.2
    Send Setups (0x01)
    This command initiates the upload of the full settings table to the QT1111 (see Section 7 on
    When this command is received, the QT1111 stops key measurement and waits until 42 bytes of
    setup data have been received. Key acquisition will restart after all the setup data has been
    received.
    If enabled, a CRC check byte is transmitted (both ways) after the 42 bytes to confirm that they
    have been received correctly.
    If CRC checking is not enabled, it is recommended that the host request a dump of setup data
    from the QT1111, and confirms that the data correctly matches the data sent.
    The host must wait for at least 300 s for the operation to be completed before communications
    can be re-established.
    5.3
    Calibrate All (0x03)
    This command initiates the recalibration of all sensor keys.
    The host must wait for at least 300 s for the operation to be completed before communications
    can be re-established.
