Codec Encoding

The BCM4354 can support SBC and mSBC encoding and decoding for wideband speech.

Multiple Simultaneous A2DP Audio Stream

The BCM4354 has the ability to take a single audio stream and output it to multiple Bluetooth devices

simultaneously. This allows a user to share his or her music (or any audio stream) with a friend.

FM Over Bluetooth

FM Over Bluetooth enables the BCM4354 to stream data from FM over Bluetooth without requiring the host to

be awake. This can significantly extend battery life for usage cases where someone is listening to FM radio on

a Bluetooth headset.

Burst Buffer Operation

The BCM4354 has a data buffer that can buffer data being sent over the HCI and audio transports, then send

the data at an increased rate. This mode of operation allows the host to sleep for the maximum amount of time,

dramatically reducing system current consumption.

Adaptive Frequency Hopping

The BCM4354 gathers link quality statistics on a channel by channel basis to facilitate channel assessment and

channel map selection. The link quality is determined using both RF and baseband signal processing to provide

a more accurate frequency-hop map.
