For example, a first Bluetooth (BT) device may be configured to operate in a role of a peripheral device over a BT link between the first BT device and a second BT device; and to initiate a role switch to switch the first BT device from the role of the peripheral device to a role of a central device over the BT link between the first BT device and the second BT device, based on a determination that the BT link between the first BT device and the second BT device is to be operated as an audio link to communicate audio data between the first BT device, as an audio source, and the second BT device, as an audio sink.

Various arrangements are presented for increasing a link margin of a wireless audio link. A short-range wireless communication link having a first physical layer (PHY) symbol rate is established between an audio source device and an audio output device. An audio stream is transmitted using the communication link, which includes a connected isochronous stream (CIS) link. A number of packet retransmissions are detected on the CIS. Based on the detected number of packet retransmissions on the CIS, the first PHY symbol rate of the CIS can be altered to a second PHY symbol rate for transmitting the audio stream.

Link margin improvements using a variable physical layer symbol rate

For example, a Bluetooth (BT) device may include a first BT radio; a second BT radio; and a BT controller configured to control BT activities of the first and second BT radios, the BT controller configured to process a Host Controller Interface (HCI) command from a host processor of the BT device to setup a BT activity, the BT controller configured to identify one or more scheduling requirements of the BT activity based on the HCI command, and, based on the scheduling requirements of the BT activity, to dynamically schedule the BT activity to a selected BT radio from the first and second BT radios.
