Bluetooth controller V1.2 and V2.0 + EDR features

The Bluetooth controller is backward compatible with the Bluetooth specification V1.2 [] and

V2.0 + EDR []. Here below is a list with the main features of those specifications:

●

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

and as Slave

●

Fast Connection: Interlaced scan for Page and Inquiry scan, answer FHS at first

reception, RSSI used to limit range

●

Extended SCO (eSCO) links: supports EV3, EV4 and EV5 packets

●

Channel Quality Driven Data Rate change (CQDDR)

●

QoS Flush

●

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

applications on different Slaves

●

L2CAP Flow & Error control

●

LMP SCO handling

●

2 Mbps packet types

–

ACL: 2-DH1, 2-DH3, 2-DH5

–

eSCO: 2-EV3, 2-EV5

●

3 Mbps packet types

–

ACL: 3-DH1, 3-DH3, 3-DH5

–

eSCO: 3-EV3, 3-EV5

5.5

Bluetooth controller V2.1 + EDR (“Lisbon”)

●

Encryption Pause/Resume (EPR)

●

Extended Inquiry Response (EIR)

●

Link Supervision Time Out (LSTO)

●

Secure Simple Pairing

●

Sniff Subrating

●

Quality of Service (Qos)

–

Packet Boundary Flag

–

Erroneous Data Delivery

5.6

Processor and memory
