Bluetooth/WLAN Dual Mode Low Power and High Speed Communications Protocol and Interface

Abstract:

A low power device has a Bluetooth connection and a WLAN interface that can be enabled for high speed communication. The low power device is coupled to an application program running on a remote computer such as a tablet over Bluetooth. When a large amount of data is requested, the high speed WLAN interface is enabled as an Access Point (AP) and data transmitted or received over the low power device AP WLAN interface until the block of data is transferred, after which the WLAN connection is torn down, and the WLAN interface disabled. In this manner, the power consumption during high speed data transfers is minimized.
