10.0 Integrated Firmware
(Continued)
10.1.4 Default Link Policy
Each Bluetooth Link can be configured to support M/S role
switch, Hold Mode, Sniff Mode and Park Mode. The default
link policy defines the standard setting for incoming and
outgoing connections.
10.1.5 Audio Support
The LMX9830 offers commands to establish and release
synchronous connections (SCO) to support Headset or
Handsfree applications. The firmware supports one active
link with all available package types (HV1, HV2, HV3), rout-
ing the audio data between the bluetooth link and the
advanced audio interface. In order to provide the analog
data interface, an external audio codec is required. The
LMX9830 includes a list of codecs which can be used.
