Abstract:
This disclosure describes a system (100, 130) for a USB to Bluetooth audio bridging method and apparatus. The system includes a host device (102) having a first universal serial bus (USB) interface (107) and a second USB interface (110); an adaptor (108) in connection with the first USB interface (107) which is compatible to operate based on a Bluetooth-type communication protocol; a peripheral device (106) coupled to the second USB interface (110); and a mobile communication device (104) linked to the host device (102) via the adaptor (108). The mobile communication device (104) communicates an audio data signal to the adaptor (108) and an audio bridging device (116). The audio bridging device (116) maps the second USB interface (110) to the adaptor (108) and routes audio data signals alone or in combination with another audio data signals to the peripheral device (106) via the second USB interface (110).
Abstract:
According to one embodiment, the invention relates to a method comprising: transmitting (410), by an apparatus, a message to detect one or more wireless communication devices; receiving (420), in response to the transmitted message, at least one response message comprising at least identification information regarding a wireless communication device; determining (430) that the apparatus has data suitable for transmitting to the wireless communication device without establishing a formal communication connection with the wireless communication device; and transmitting (440) one or more subsequent messages to the wireless communication device in response to the received response message, wherein the one or more subsequent messages comprise at least the data suitable for transmitting to the wireless communication device without establishing a formal communication connection.
Abstract:
Among other things, this document describes a computer-implemented method. The method can include receiving, at a first device, an indication of user input to cause the first device to establish a wireless data connection with another device. A determination can be made at the first device that one or more sensors on the first device are oriented toward a second device. In response to at least one of (i) receiving the indication of user input to cause the first device to establish a wireless data connection with another device and (ii) determining that the one or more sensors on the first device are oriented toward the second device, a first wireless data connection can be established between the first device and the second device. A first stream of audio data can be received and played at the first device.
Abstract:
A BLUETOOTH reconnection method is used in a BLUETOOTH connection system that includes a first device and a second device. The method includes that the first device sends a BLUETOOTH Low Energy (BLE) advertising signal to the second device after a BLUETOOTH connection between the first device and the second device is disconnected. If the second device determines that the received BLE advertising signal is a first BLE advertising signal, the second device does not page the first device, and waits to receive a page packet sent by the first device. If the second device determines that the received BLE advertising signal is a second BLE advertising signal, the second device actively pages the first device, and the first device waits to receive a page packet sent by the second device.
