A2DP Source

This example shows how to set up iWRAP into A2DP sink mode i.e. to receive audio. In

this mode iWRAP can accept Bluetooth A2DP connections or connect an A2DP source. The
basic configuration steps are displayed in the figure below:

A2DP source example

When audio streaming needs to be enabled

A2SP STRAMING START

command needs to

be given to iWRAP and on the other hand when streaming needs to be stopped

A2DP

STRAMING STOP

command should be issued.
