A hands-free device is disclosed, in which a memory and a hardware processor connected to the memory are included. The hardware processor establishes a connection with a mobile phone using a hands-free communication protocol for making a hands-free call. The hardware processor establishes a connection with the mobile phone using a data transfer protocol for transferring phone data about a phone to receive the phone data transferred from the mobile phone, and stores the phone data into the memory. When a phone communication state of the mobile phone is transitioned while the phone data is being transferred, the hardware processor executes transfer control in accordance with transfer criteria, each depending on a type of the phone data being transferred and the phone communication state after the transition.

Systems, methods and non-transitory computer readable media for allowing a user to switch between wearable items that have been paired or associated with an electronic device, such as a smartphone, are described. In one embodiment, the wearable items automatically detect a removal of a first wearable item from a user's body and an attachment of a second wearable item to the user's body. Messages from the wearable items are transmitted to the electronic device to allow the electronic device to switch the active wearable item from the first wearable item to the second wearable item. The switch can occur while the electronic device is in a locked state, and the electronic device can synchronize the second wearable item with data received from the first wearable item. Other embodiments are also described.

A method for interacting of a PSAP with a portable network device includes detection of a trigger signal of an eyewitness-button and storing call log data of the call by the PSAP. A signaling connection between the portable network device and the PSAP can be set up and a geographical area of interest close to the actual location of the portable network device can be determined. At least one external portable network device of a list can be scanned and the scanning result from the at least one external portable network device of the list can be forwarded to the PSAP via the signaling connection after it is protected by the PSAP. Systems and devices can utilize embodiments of the method.

Embodiments of this application disclose a communication service status control method, a terminal device, and a computer-readable storage medium. The method includes: If it is detected that a preset trigger condition is met, enabling a first communication service corresponding to a target service, and displaying a status of a switch control of the first communication service as a first state, where the first state is used to describe that the first communication service is in an enabled state; and if a first operation for the switch control is detected and it is detected that a target service is in a running state, displaying a status of a switch control of a second communication service as a second state, and maintaining the second communication service in an enabled state, where the second state is used to describe that the second communication service is in a disabled state.

Disclosed are a device switching method for a display apparatus and a display apparatus. The method includes: recognizing a first class of device of a Bluetooth device, and presenting the first class of device in a first user interface; in response to a device switch command being received within a specified time from outside, determining that the first class of device is different from an actual second class of device, updating the first class of device in the first user interface to the second class of device, and interacting with the Bluetooth device according to the second class of device; and in response to no device switch command being received within the specified time input from outside, determining that the first class of device is the same as the actual second class of device, and interacting with the Bluetooth device according to the second class of device.

A method for Bluetooth audio multi-streaming by a first electronic device includes establishing a Broadcast Isochronous Group (BIG) with second electronic devices, broadcasting a first audio to the second electronic devices over the BIG, detecting an audio event at the first electronic device while broadcasting the first audio to the second electronic devices, determining one or more primary electronic devices of the second electronic devices and one or more secondary electronic devices of the second electronic devices, and continuing to broadcast the first audio over the BIG to the one or more secondary electronic devices and concurrently unicasting a second audio that corresponds to the audio event over a Connected Isochronous Group (CIG) connection to the one or more primary electronic devices.

The present disclosure describes receiving a trigger operation indication that content has been selected by a user device, and determining whether the content offers a recurring audio content data. The operation may also include retrieving a first audio content and transmitting the first audio content to the user device.

The present application provides various embodiments for a Bluetooth headset or other wearable communication device that pairs via a Bluetooth protocol with a two way radio (hardware or software), thereby enabling hands-free activation and deactivation of the paired two way radio. Intelligent speech control is enabled for the two way radio using a start phrase to trigger talk or transmit mode of the two way radio and an end phrase to trigger the receive or listen mode of the two way radio. Tones can be emitted when a mode is entered as feedback to the user as to which mode the two way radio has entered.

A method for displaying a BLUETOOTH device identifier includes a first electronic device that broadcasts a first BLUETOOTH packet. The first BLUETOOTH packet includes first indication information. A second electronic device broadcasts a second BLUETOOTH packet. A third electronic device displays a BLUETOOTH scanning interface, and scans a third BLUETOOTH packet. The third electronic device displays the first link identifier and a second link identifier on the BLUETOOTH scanning interface in response to receiving the first BLUETOOTH packet and the second BLUETOOTH packet. The third electronic device displays the first link identifier in the highlighting manner on the BLUETOOTH scanning interface in response to the first BLUETOOTH packet comprising the first indication information.

Provided are a Bluetooth data transmission method and apparatus, a terminal and a storage medium. The Bluetooth data transmission method includes: detecting the number of connected Bluetooth devices and types of connected Bluetooth devices; determining, according to the number of connected Bluetooth devices and types of the connected Bluetooth devices, attribute states of the connected Bluetooth devices; and transmitting, according to the attribute states, to-be-outputted Bluetooth data to one of the connected Bluetooth devices.
