HCI only active
Average current when waiting for HCI command UART, USB, or SPI 4.8 mA
transports.

Inquiry Scan (1.28 sec)
Page Scan (R1)
UART transport active, external LPO clock available, HV LDO
disabled and in bypass mode.
Periodic scan rate is 1.28 sec.
Periodic scan rate is R1 (1.28 sec).

Inquiry Scan + Page
Scan (R1)
Both inquiry and page scans are interlaced together at 1.28 sec
periodic scan rate.
630 μA
Sniff master (500 ms)
Attempt and timeout parameters set to 4. Quality connection
which rarely requires more than minimum packet exchange.
175 μA
Sniff slave (500 ms)
Attempt and timeout parameters set to 4. Quality connection
160 μA
which rarely requires more than minimum packet exchange. Sniff
master follows optimal sniff protocol of BCM20705 master.
Sniff (500 ms) + Inquiry/ Same conditions as Sniff master and Page Scan (R1). Scan maybe 455 μA
Page Scan (R1)
either Inquiry Scan or Page Scan at 1.28 sec periodic scan rate.
Sniff (500ms) + Inquiry Same conditions as Sniff master and Inquiry Scan + Page Scan. 760 μA
Scan + Page Scan (R1)
