Key Features of HCI Stack
Bluetooth components: Basedband (including LC), LM and HCI.
Standard USB v1.1 and UART (H4) HCI Transport Layers.
All standard radio packet types.
Full Bluetooth data rate, up to 721kbps asymmetric.
Operation with up to seven slaves.
Maximum number of simultaneous active ACL connections: 7
Maximum number of simultaneous active SCO connections: 3
Operation with up to 3 SCO links, routed to one or more slaves.
Role switch: can reverse Maser/Slave relationship.
All standard SCO voice codings, plus “transparent SCO”.
Standard operating modes: page, inquiry, page-scan and inquiry-scan.
All standard pairing, authentication, link key and encryption operations.
Standard Bluetooth power saving mechanisms: Hold, Sniff and Park modes,
including “Forced Hold”.
Dynamic control of peers’ transmit power via LMP.
Master/Slave switch.
Broadcast.
Channel quality driven data rate.
All standard Bluetooth Test Modes.
Standard firmware upgrade via UART interface.
Standard firmware upgrade via USB interface.
Provides manufacture-specific HCI extension commands with the following features:
Access to the chip’s general-purpose PIO port.
Access to the chip’s Bluetooth clock.
The negotiated effective encryption length on established Bluetooth links.
Access to the firmware’s random number generator.
Controls to set the default and maximum transmit powers.
Dynamic UART configuration.
Radio transmitter enable/disable.
A UART “break” condition can be used in two ways:
Presenting a UART break condition on the module can force the chip to
perform a hardware reboot.
Presenting a break condition at boot time can hold the chip in a low power
state, thus preventing normal initialization while the condition exists.
Hardware low power modes: Shallow Sleep and Deep Sleep.
SCO channels are normally routed over HCI. However, up to three SCO channels
can be routed over the chip’s single PCM port (at the same time as routing other
SCO channels over HCI).
