Appendix B. Fuzzy Auto On/Off
iBT-GPS supports fuzzy auto on/off. It can automatically enter the
sleeping mode after your turning off the Bluetooth connectivity, thus you
can always power it on with very low power consumption.
With fuzzy auto on/off, if the connection between your device and
iBT-GPS is successful, iBT-GPS will wake up itself and the blue LED of
iBT-GPS will be quickly blinking again (every 2 sec) and the orange LED
of iBT-GPS will also be on.
