2.3.7

SI,<H16>

This command only applies to Bluetooth Classic.

The Inquiry Scan Window command sets the length of time the device spends enabling

an inquiry scan (discoverability). The minimum value is 0x0012, corresponding to

about a 1% duty cycle. The page scan interval is fixed at 0x1000. The default window

is 0x0100. The maximum value is 0x0800. Set this parameter to 0x0000 to disable

inquiry scanning and render the device undiscoverable. If the host already made the

pairing, the inquiry scan is not used.

Default:

0100
