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.

Apparatus, system and method of bluetooth role switch

The present disclosure provides a controller configured to detect a reconnection single point of failure in a Bluetooth or other Low-Energy wireless connection attempt with a peripheral device and implement a procedure to reconnect with the peripheral device by delaying the reporting of the connection failure to a host processor. Instead, the controller initiates an additional scan on a different frequency band than used in the initial attempt in a further attempt at connecting with the peripheral device.

Methods and devices for connection retry after failed connection attempt in wireless systems

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.

Apparatus, system and method of scheduling communication via a plurality of Bluetooth radios

An apparatus of a wireless system, product to be implemented at a computer process of the wireless system, and method to operate the apparatus. The apparatus includes an input; an output; and processing circuitry connected to the input and to the output, the processing circuitry to implement logic to: receive, through the input and from a first modem of the wireless system, information on a traffic attribute relating to communication in compliance with a first wireless communication protocol; determine, based on the traffic attribute, blacklisted channels to be avoided during a discovery procedure by a second modem of the wireless system, the discovery being in compliance with a second wireless communication protocol; and send, through the output, information based on the blacklisted channels to the second modem to cause the second modem to avoid the blacklisted channels during the discovery procedure.

Mechanism to improve Bluetooth connection time in the presence of active cellular or WiFi traffic

Methods, apparatus, and computer-readable media are described to encode, by a first station (STA), a polling signal for periodic transmission to a second STA during each air activity instance of a plurality of air activity instances. The first STA detects an interface between a MAC layer and a software stack of a communication protocol is in a low-power state. The communication protocol is associated with a communication link between the first STA and the second STA. An empty packet from the second STA is decoded. The empty packet is received in response to the polling signal transmitted during an air activity instance of the plurality of air activity instances. The periodicity of the periodic transmission of the polling signal is adjusted based on the detected low-power state and the decoded empty packet.

Idle connection optimization for wireless devices

A device and a method for mixed mode communication are disclosed. For example, a Bluetooth master device transmits data packets to a Bluetooth slave device and receives acknowledgments from the Bluetooth slave device, by controlling a transceiver to transmit the data packets based on a Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) protocol, and to receive the acknowledgements packet (ACK) based on a Bluetooth Low Energy (BLE) protocol. In another example, a Bluetooth slave device receives the data packets from a Bluetooth master device and transmits acknowledgments to the Bluetooth master device, by controlling a transceiver to receive the data packets based on a BR/EDR protocol, and to transmit the ACK based on a BLE protocol.

Methods, apparatus, systems and articles of manufacture to improve Bluetooth low energy streaming connection efficiency are disclosed herein. An example method includes accessing a request received at a first device from a second device, the request requesting set up of an isochronous link between the first device and the second device, the request including a configuration identifier. Whether the configuration identifier identifies a configuration stored at the first device is determined. In response to determining that the configuration identifier identifies the configuration stored at the first device, the isochronous link using the stored configuration.

The mobile device may, in an ESCO retransmission slot of the ESCO interval: attempt to decode, from the slave device, a request for retransmission of the packet. If the request for retransmission is not successfully decoded, the mobile device may determine whether the request for retransmission was sent during the ESCO retransmission slot based at least partly on a channel energy level detected during the ESCO retransmission slot. If it is determined that the request for retransmission was not sent during the ESCO retransmission slot, the mobile device may refrain from monitoring subsequent ESCO retransmission slots of the ESCO interval. If it is determined that the request for retransmission was sent during the ESCO retransmission slot, the mobile device may monitor one or more of the subsequent ESCO retransmission slots of the ESCO interval.
