Bluetooth settings dialog for Bluetooth Duo
Bluetooth Settings dialog for Bluetooth Duo, shown in the A2DP Source, HFP Audio Gateway, AVRCP Target profile set.
This topic explores Bluetooth Duo settings dialog. The
legacy Bluetooth settings dialog is discussed begin-
ning on page 148.
This dialog provides settings for Bluetooth discovery,
pairing, connection and other configuration. Unlike
most APx settings, Bluetooth profile selection, pairing
and connection settings are global to the APx project.
Settings made here affect both Bluetooth source and
sink configurations across all signal paths in the proj-
ect.
A flow chart depicting discovery, pairing and connec-
tion paths is shown on page 139.
APx Profile Set
APx has four sets of profiles that the Bluetooth Option
module can assume. Each set lists the profiles avail-
able for connection and/or the profiles available for
access by a remote device. Choose an APx Bluetooth
Profile Set here.

In A2DP Source, the APx Bluetooth trans-
mitter mutes the audio when the average
signal level falls below –54 dBFS for more
than 1 second. We recommend maintain-
ing test levels above –54 dBFS for meaning-
ful results.
