Tabl e 14: Power consumptions
Note:
Power consumption depends on the firmware used. Typical values are shown in the table.
Sniff mode ----- In Sniff mode, the duty cycle of the slave’s activity in the piconet may be reduced. If a slave is in active mode
on an ACL logical transport, it shall listen in every ACL slot to the master traffic, unless that link is being treated as a
scatternet link or is absent due to hold mode. With sniff mode, the time slots when a slave is listening are reduced, so it
benefits the power consumption of the slave and the master shall only transmit to a slave in specified time slots. The sniff
anchor points are spaced regularly with an interval of Tsniff, which depends on the firmware used.
