Hi Guys !!! Hope all is well
I am going to discus Bluetooth ACL and SCO in Android.
Voice data in Bluetooth hands free kit is an example for this
This narrow band audio is called "Bluetooth voice" type
Where as ACL is for all other BT data transfer including High quality audio/video data
Example is music playback through A2DP. This is high bandwidth data and hence called "Advanced Audio"
SCO is fixed bandwidth channels and can have maximum 3 channels per device,
but throughput of ACL varies with other active connections(SCO and ACL) at that time

- ACL= Asynchronous Connection-Less
- SCO = Synchronous Connection Oriented.
- SCO is Point to Point Connection between only one master and only one slave
- ACL is multi-point connection between one master and many slaves
