Bluetooth controller 1.1 features

The Bluetooth Controller is based on Ericsson Technology Licensing Baseband Core (EBC)

and it is compliant with the Bluetooth specification 1.1:

–

Point to multipoint (up to 7 Slaves)

–

Asynchronous Connection Less (ACL) link support giving data rates up to 721

kbps

–

Synchronous Connection Oriented (SCO) link with support for 2 voice channels

over the air interface

–

Flexible voice format to Host and over the air (CVSD, PCM 13/16 bits, A-law,

µ-

law)

–

HW support for packet types: DM1, 3, 5; DH1, 3, 5; HV1, 3; DV

–

Scatternet capabilities (Master in one piconet and Slave in the other one; Slave in

two piconets). All scatternet v.1.1 errata supported

–

Ciphering support up to 128 bits key

–

Paging modes R0, R1, R2

–

Channel Quality Driven Data Rate

–

Full Bluetooth software stack available

–

Low-level link controller

–

Fully v.1.1 compatible via restricted mode

(e.g.: add_SCO_connection, read_local_supported_features, read_country_code)

5.5

Bluetooth controller 1.2 features

The Bluetooth Controller is also compliant with the Bluetooth specification 1.2:

–

Adaptive Frequency Hopping (AFH): hopping kernel, channel assessment as

Master and as Slave

–

Faster connection: Interlaced scan for Page and Inquiry scan, answer FHS at first

reception, RSSI used to limit range

–

Extended SCO (eSCO) links: supports EV3 and EV5 packets

–QoS Flush

–

Synchronization: BT clocks are available at HCI level for synchronization of

parallel applications on different slaves

–

L2CAP Flow & Error control

–

LMP improvements

–

LMP SCO handling

–

Parameter ranges update
