For example, an apparatus may include logic and circuitry configured to cause a Bluetooth (BT) broadcast transmitter to transmit one or more broadcast data Protocol Data Units (PDUs) including broadcast data. For example, the BT broadcast transmitter may be configured to transmit a broadcast control PDU after the one or more broadcast data PDUs. For example, the broadcast control PDU may include an opcode field and a control data field. For example, the opcode field may include a predefined opcode value configured to indicate a recipient-targeted data PDU type. For example, the control data field may include targeted data for one or more targeted recipients.
