8results about "Devices with bluetooth interfaces" patented technology

A wireless communication system including an adapter is provided. The adapter is configured to connect with a host through a universal serial bus interface and connect with a handset through a Bluetooth interface to form a Bluetooth connection. After the adapter connects with the host through the universal serial bus interface and connects with the handset through the Bluetooth interface, the adapter is configured to provide a first IP address of the host to the handset to establish a Wi-Fi connection between the host and the handset. The Bluetooth connection is further configured to transmit an encryption key between the host and the handset. The Wi-Fi connection is not configured to transmit the encryption key.

A system and method in which a user application on a mobile device facilitates hands-free fare validation and gateless entry / exit at a transit facility like a transit station or a transit vehicle. The user application communicates with a Bluetooth gateway to authenticate the device and provides device-specific information for device identification and location determination. The user application also sends a secure token to the gateway to validate an electronic ticket stored in the device. A positioning unit uses the device-specific information to generate a timestamped location data for the device. A camera monitors the device user's movement and generates another timestamped location data for the device. A controller driver compares two timestamped location data to determine that the user of the device is approaching a gateless entry point and allows the user to avail a transit service through the gateless entry point when the electronic ticket is valid and active.

According to one embodiment, an electronic device (101) comprises: a communication circuit (190); one or more processors (120) including processing circuitry; and a memory (130) including instructions, wherein, when individually or collectively executed by the one or more processors, the instructions cause the electronic device to establish, through the communication circuit, a connection with one or more external electronic devices (102, 104, 211, 212, 213, 214, 215, 216), determine, from among the one or more BISs included in a broadcast isochronous group (BIG), a broadcast isochronous stream (BIS) to be received by the one or more external electronic devices, and transmit, through the communication circuit, control information including an index of the one or more external electronic devices and an index of the determined BIS. Other embodiments are possible.

The present disclosure provides a method and apparatus for a system including multiple audio devices. A method for a system including multiple audio devices is provided, which is performed by a first audio device of the multiple audio devices and comprises: receiving an instruction indicating the first audio device to be set as a primary device of the system and a second audio device to be set as a secondary device of the system; transmitting a setting instruction to the second audio device as indicated in the received instruction to set the second audio device as the secondary device of the system; receiving a full channel audio; and transmitting the full channel audio to other audio devices in the system; wherein the primary device of the system is set to play a designated one of left and right channels as indicated in the received instruction and the secondary device of the system is set to play the other one of the left and right channels.

An electronic device is provided. The electronic device may assist an audio sink device. The electronic device may comprise: a memory that stores instructions; a display; a communication circuit for BLE; and a processor. The instructions, when executed by the processor, may cause the electronic device to: perform a first scan for an extended advertisement caused around the electronic device by using the communication circuit; receive an advertised packet via the extended advertisement of an external electronic device; display, on the display, a device list including a visual object representing the external electronic device as a candidate audio source device; and synchronize with a periodic advertisement of the external electronic device according to a second scan for the periodic advertisement caused around the electronic device.

This application provides a screen projection method and an electronic device. The method includes: detecting a position of one or more other electronic devices relative to a first electronic device by using a Bluetooth angle of arrival (AOA) technology (S1601); determining a target device from the one or more other electronic devices based on the position of the one or more other electronic devices relative to the first electronic device (S1602); detecting a screen projection operation (S1603); and sending first information to the target device in response to the screen projection operation, so that the target device displays or plays the first information (S1604). In the method, the electronic device may automatically determine a target electronic device from a plurality of electronic devices, and then project a screen on the target electronic device, to facilitate operations and improve user experience.

A method for communicating data by an electronic device is provided. The method includes transmitting a signal including audio / video (A / V) data to a first external electronic device through a first communication module, while connected with the first external electronic device, generating data or a signal unrelated to the A / V data or receiving the data or signal unrelated to the A / V data from an external electronic device other than the first external electronic device, and providing an audio or a video through a display or an embedded sound device based on at least a portion of the data or the signal unrelated to the A / V data or transmitting the at least a portion of the data or the signal unrelated to the A / V data to a second external electronic device through a second communication module.

In one of the various implementations of this disclosure, a first device establishes short-range communication with a second device. The first device obtains related information of the second device based on the short-range communication. The first device sends the related information of the second device and related information of the first device to a third device. The first device then receives paging from the third device, where the paging is sent by the third device based on the related information of the second device and the related information of the first device.
