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
