[CYBT-333032] Current consumption (Connected, Connected + SNIFF)

[YoJa_3107936]

Hi Everyone,

According to the data sheet of CYBT-333032
Document Number: 002-25196 Rev. * A
Table 13

1. Connected (Connected with no data transfer) current consumption is 2.6mA.
2. Connected + SNIFF (Connected with no data transfer + SNIFF (500 ms)) consumes 0.95mA.

Please tell me the reason why 2 is smaller than 1.
Is it correct as the following guess?
(1 is the operation at the time of master, 2 is the operation at the time of slave?)

Thanks,

Yang

Hi,

In Sniff mode, the duty cycle of the slave’s activity in the piconet may be reduced.  The time slots when a slave is listening are reduced, so the master shall only transmit to a slave in specified time slots.
