A terminal receives an input operation of adding a new device to a target account by a user. The terminal obtains device information of a to-be-added first device in response to the input operation, where the device information includes a MAC address of the first device. The terminal establishes a P2P connection to the first device based on the device information. After the terminal successfully establishes the P2P connection to the first device, the terminal displays the first device as an online device of the target account. The terminal receives a control operation entered by the user on the first device. The terminal sends a control instruction to the first device through the P2P connection in response to the control operation.

Device control method and terminal

A device control method is disclosed. When a first device and a second device are required to perform actions, a first instruction is sent to the first device, and a second instruction is sent to the second device after a first time interval; and when the first device, the second device, and a third device are required to perform actions, the first instruction is sent to the first device, the second instruction is sent to the second device after the first time interval, and a third instruction is sent to the third device after a second time interval, where the second time interval is greater than the first time interval, so that the third device performs a third action after a delay.

Embodiments of the disclosure pertain to an optical transmitter comprising a laser configured to generate an optical signal from a single-ended electrical signal, a housing or (sub)assembly containing the laser, a driver configured to generate the single-ended electrical signal, a direct current (DC) return path, and an alternating current (AC) return path. The laser has a DC power pin, and the DC power has a DC component and an AC component. The driver has a first impedance at a first output through which the single-ended electrical signal passes. The housing or (sub)assembly has a second impedance matching the first impedance. The DC return path comprises an inductor and is configured to carry or conduct the DC component of the DC power from the laser (e.g., to an input pin on the driver). The AC return path is configured to carry or conduct the AC component of the DC power from the laser. Methods of using and manufacturing the same are also disclosed.

The present invention relates to an antenna splitting method in an active antenna system and a controller, where the method includes: when load of an active antenna system AAS cell is greater than or equal to a load threshold, if a cell in an optimized area is not overloaded, load of a first cell is less than the load of the AAS cell, and load of a second cell is less than the load of the AAS cell, acquiring a first antenna parameter combination corresponding to a maximum capacity of the optimized area; and splitting an AAS antenna according to the first antenna parameter combination. The antenna splitting method in an active antenna system and the controller according to embodiments of the present invention can effectively reduce the load of a heavily loaded AAS cell, and effectively increase a capacity of the optimized area.
