Establishing a bluetooth classic connection using an existing bluetooth low energy connection

摘要

The embodiments set forth techniques for enabling two devices to seamlessly construct/deconstruct a BTC connection on an as-needed basis. According to some embodiments, the technique involves exchanging, over a BTLE connection that exists between the two devices, information that enables the two devices to establish a BTC connection in a timely and power-efficient manner. To construct a BTC connection, a master device transmits, to a slave device using Link Layer (LL) control messages over an existing BTLE connection, clock information associated with the master device, a Logical Bluetooth Classic Transport Address (LT_ADDR) associated with the slave device, and other information. In turn, the BTC connection can be established between the master device and the slave device using the exchanged information. This technique can require less time and consume less power compared with conventional approaches that do not use existing communication channels to establish a BTC connection.
