Abstract
A battery-powered mobile device allows concurrent wireless transception of control data via standard Bluetooth low energy (BLE) and proprietary audio streaming, using the same physical layer of the radio. Following each BLE connection event, an enhanced link layer clocks a remaining duration of the current idle time period. Requests provided to the enhanced link layer include time slot information for the proprietary audio bursts. The enhanced link layer determines, based on the time slot information, whether each requested burst can be completed during the remaining duration of the current idle time period, appropriately linking payload information of each packet with the BLE control data stack or with a proprietary audio stack, with the BLE control data having priority over the proprietary audio requests.
