4.9 FW Version
User can verify KDC Bluetooth firmware version in BT FW menu.
4.10 Wakeup Nulls
The KDC sends three leading Null bytes to wake up connected Bluetooth device. This feature can be
disabled if connected Bluetooth device doesn’t require additional bytes to wake up.
4.11 Autolock Time
iPhone/iPad/iPod touch loses incoming Bluetooth data in sleep mode. Users can set KDC Autolock time to the
same Autolock time of your iPhone/iPad/iPod touch to use automatic wakeup feature in HID mode to prevent
data loss. There would be a one second delay of barcode transmission if Autolock time is set to more than one
minute and the barcode scan interval is larger than auto lock time. The autolock time would be set as 0, 1, 2, 3,
4, 5, 10, 15 minutes. 0 means iPhone/iPad/iPod touch never enters sleep mode.
4.12 BT Toggle
