12.7 iWRAP to iWRAP Serial Port P SCO connection
iWRAP also supports SCO (audio) connections. This example shows how to open a
simultaneous Serial Port Profile and SCO audio connection between two iWRAP modules.

Figure 15: Simultaneous SPP and SCO connection between two iWRAP modules
 SET CONTROL CD 80
This configuration enables Carrier Detect (CD) signal to PIO7. The purpose is to raise PIO7
when the Serial Port Profile connection becomes active.
 SCO ENABLE
This command is needed to generally enable SCO connections. Alternatively one time
configuration SET CONTROL INIT SCO ENABLE could be use, which causes iWRAP to
execute SCO ENABLE in every restart. If HFP profile is enabled SCO ENABLE is not
needed
 SET CONTROL BIND 0 80 RISE SCO OPEN 0
This setting binds SCO OPEN 0 command to PIO7. The command gets priority 0 and is
executed on the rising edge. So when PIO7 is raised by SET CONTROL CD command
iWRAP executed SCO OPEN 0 and opens and activates SCO connection between the
iWRAP modules. This setting assumes (0 used as link_id) that the Serial Port Profile
connection is the first and only connection iWRAP has. Alternatively the command could be
given manually to iWRAP using syntax SCO OPEN {link_id} .
