The ARC EMSK processor was running MQX RTOS to receive audio stream from an Android smart phone. SEARAN dotstackTM is a valuable option for embedded Bluetooth development when resources are scarce and to be reserved for other necessary functionality. See comparison to a well known competitor stack option below.
