Using alsa utilities to record/play audio on bluetooth directly once SCO connection with the headset is established. Use BluetoothSCOApp application to establish SCO link with an active Bluetooth headset.

Please check if the bluetooth firmware for your device supports SCO over PCM by default.
I got the same error when using a version of WL1271 BT firmware for omap3evm which did not support SCO over PCM.
