Hardware Description Manual
4.1.1 Key Features of the HCI Stack: Standard Bluetooth Functionality
Bluetooth v2.1 + EDR mandatory functionality:

AFH, including classifier

Faster connection - enhanced inquiry scan (immediate FHS response)

LMP improvements

Parameter ranges
Optional Bluetooth v2.1 + EDR functionality supported:

AFH as Master and Automatic Channel Classification

Fast Connect: Interlaced Inquiry and Page Scan plus RSSI during Inquiry

eSCO, eV3 +CRC, eV4, eV5

SCO handle

Synchronization
The firmware was written against the Bluetooth v2.1 + EDR specification.

Bluetooth components:
◦
Baseband (including LC)
◦
LM
◦
HCI

Standard USB v2.0 and UART HCI Transport Layers

All standard radio packet types

Full Bluetooth data rate, enhanced data rates of 2 and 3Mbps

Operation with up to seven active slaves
1

Scatternet v2.5 operation

Maximum number of simultaneous active ACL connections: 7

Maximum number of simultaneous active SCO connections: 3
2

Operation with up to three SCO links, routed to one or more slaves

All standard SCO voice coding, 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

A block of radio test or BIST commands allows direct control of the chip's radio. This aids the development

of modules' radio designs, and can be used to support Bluetooth qualification.

VM. The firmware provides the VM environment in which to run application-specific code. Although the is mainly
used with BlueLab and RFCOMM builds (alternative firmware builds providing L2CAP, SDP and

RFCOMM), the VM can be used with this build to perform simple tasks such as flashing LEDs via the chip's

PIO port.

Hardware low power modes: Shallow Sleep and Deep Sleep. The chip drops into modes that significantly

reduce power consumption when the software goes idle.

SCO channels are normally routed via HCI (over BCSP). However, up to three SCO channels can be routed

over the chip's single PCM port (at the same time as routing any remaining SCO channels over HCI).

This is the maximum allowed by Bluetooth v2.1 + EDR specification.

BlueCore 5 chip supports all combinations of active ACL and SCO channels for both master and
slave operation, as specified by the Bluetooth v2.1 + EDR specification.
The firmware's supported Bluetooth features are detailed in the standard PICS documents, available from
