3.3 Multiplexing Mode
In iWRAP version 2.1.0 and newer, there is a special mode called multiplexing mode. In
this mode, iWRAP does not have separate commands or data modes, but data, commands
and events are all handled in one single mode. There is, however, a special protocol to
separate commands and events from the actual data. This protocol must be used between
the host system and iWRAP firmware.
The advantage of this multiplexing mode is that several Bluetooth connections can be
handled simultaneously and there is no need to do time consuming data-command-data
mode switching. However the downside is that the performance of iWRAP is reduced, since
the firmware needs to handle the multiplexing protocol and the overhead it causes.
To learn more about multiplexing mode, please see the description of “ SET CONTROL
MUX ” command.
3.4 HFP mode
iWRAP 2.2.0 and newer support Bluetooth Hands-Free (v.1.5) profile. This profile include a
lot of control messaging and events, which is handled in the command mode i.e. when a
HFP connection is opened or received no state transition occurs, but iWRAP stays in the
command mode, where all HFP messaging is done. Please refer to HFP profile usage for
more information.
3.5 OPP mode
IWRAP 2.1.0 and newer support Bluetooth Object Push Profile (OPP) profile. The operation
is this profile is quite similar to HFP mode i.e. there is no separate command and data
modes, but iWRAP always stays in the command mode. In OPP mode, Please refer to OPP
profile usage for more information.
3.6 A2DP mode
From iWRAP3 on Bluetooth Advanced Audio Distribution Profile (A2DP) is supported. This
profile includes also control messaging and events, which is handled in the command
mode i.e. when a A2DP connection is opened or received no state transition occurs, but
iWRAP stays in the command mode, where all A2DP messaging is done.
3.7 AVRCP mode
From IWRAP3 on Bluetooth Audio/Video Remote Control Profile (AVRCP) is supported. This
profile includes also control messaging and events, which is handled in the command
mode i.e. when a AVRCP connection is opened or received no state transition occurs, but
iWRAP stays in the command mode, where all AVRCP messaging is done.
