the following describes a principle of measuring an angle of arrival (AoA) of a BLE signal according to an embodiment of the present invention.

fig. 4A-4B are schematic diagrams illustrating AoA calculation of a bluetooth arrival angle according to an embodiment of the present invention. As shown in fig. 4A, a Transmitter (Transmitter)410 may transmit an AoA broadcast packet (constant frequency extension (CTE) packet) through BLE, the AoA CTE packet being a continuous modulated sequence without check and without Cyclic Redundancy Check (CRC) and Message Integrity Code (MIC). The Host of the Receiver (Receiver)420 issues antenna sequence information used in measurement through the HCI command. After the measurement is started, the controller 421 sequentially switches to the designated antenna according to the antenna sequence information issued by the Host to perform I & Q sampling, and reports the sampling information to the Host through the HCI command, and the Host calculates the relative angle.

The transmitting side 410 may control one antenna 410 to transmit the AoA CTE packet through the controller 411. The receiver 420 may control the rf switch 422 through the controller 421, and switch to the designated antenna in a certain order for receiving. The receiving side 420 has at least two antennas 423. Therein, the receiver 420 measures the angle of arrival AoA of the BLE signal of the transmitter 410. In some embodiments, in order to improve the accuracy of the estimation of the wave arrival angle, a plurality of antennas may be provided, and the array may be arranged in a straight line, a ring, a sphere, and the like, which is not limited herein.

As shown in fig. 4B, it is assumed that the receiving side 420 has two antennas (antenna a and antenna B) with a distance d, and the received BLE signal is a planar electromagnetic wave. Since antenna a and antenna B receive the BLE signals asynchronously, receiver 420 may compare the phases of BLE signals received by antenna a and antenna B, and determine the phase difference between BLE signals received by antenna a and antenna B.

Wherein, the angle of arrival (AoA) of the BLE signal can be calculated by the following formula (1):

Where θ is an arrival angle (AoA) of the BLE signal, ψ is a phase difference of the antenna a and the antenna B receiving the BLE signal, λ is a wavelength of the BLE signal, and d is a distance between the antenna a and the antenna B. Here, the θ angle may be set as an alignment angle between the first electronic device and the second electronic device, that is, the alignment angle between the first electronic device and the second electronic device may be calculated by formula (1).

The Host of the transmitting side 430 issues antenna sequence information used in measurement through the HCI command. After the measurement is started, the controller 441 of the receiving party 440 performs I & Q sampling on BLE signals sent by each antenna of the receiving party 440 through a single antenna according to antenna sequence information issued by the Host of the transmitting party 430, reports the sampling information to the Host through an HCI command, and calculates a relative angle by the Host.

the receiver 440 may control an antenna 442 through a controller 441 to receive the AoD CTE packet transmitted by the transmitter 430. The transmitting side 430 may control the rf switch 432 via the controller 431 to switch to the designated antenna in a certain order to transmit the AoD CTE packet. The transmitting party 430 has at least two antennas 433. Therein, the angle of departure AoD of the BLE signal of the transmitting party 430 is measured by the receiving party 440. In some embodiments, in order to improve the accuracy of the estimation of the wave arrival angle, a plurality of antennas may be provided, and the array may be arranged in a straight line, a ring, a sphere, and the like, which is not limited herein.

As shown in fig. 4C, it is assumed that the transmitting party 430 has two antennas (antenna a and antenna B) with a distance d, and the transmitted BLE signal is a planar electromagnetic wave. Since the antenna a and the antenna B transmit the BLE signals asynchronously, the receiving party 440 may compare the phases of the BLE signals transmitted by the antenna a and the antenna B that receive the transmitting party 430, and determine the phase difference between the BLE signals transmitted by the antenna a and the antenna B.

Wherein, the departure angle (AoD) of the BLE signal can be calculated by the following formula (2):

Where θ is the departure angle (AoD) of the BLE signal, ψ is the phase difference of the BLE signal emitted by the antenna a and the antenna B, λ is the wavelength of the BLE signal, and d is the distance between the antenna a and the antenna B. Here, the θ angle may be set as an alignment angle between the first electronic device and the second electronic device, that is, the alignment angle between the first electronic device and the second electronic device may be calculated by formula (2).

At present, in a method for controlling an electronic device in the prior art, a user needs to search a corresponding second electronic device in a terminal device, then select the second electronic device, perform a pairing connection operation, or find a second electronic device to be controlled in a device list in an App, perform a pairing connection operation on the second electronic device, and a user side can control the second electronic device through the terminal device. When a user searches for corresponding second electronic devices in the terminal device, the number of the second electronic devices in the searched second electronic devices or the device list in the App may be large, so that the user needs to select devices to be controlled from the large number of second electronic devices and then perform pairing connection operation. Therefore, the time and complexity of connecting and controlling the second electronic equipment through the terminal by the user are increased, and the user experience is not facilitated.

Therefore, the present invention provides a method for controlling an electronic device, which can realize that when a first electronic device searches for a second electronic device, if the first electronic device points to the second electronic device, the first electronic device displays device information of the second electronic device. Then, the user can select a second electronic device to be controlled on the first electronic device, and the first electronic device sends a request for establishing Bluetooth communication connection to the second electronic device, so that device connection pairing or control operation is performed.

If the first electronic device 100 is pointing to the second electronic device 200, that is, the first alignment angle of the first electronic device 100 with respect to the second electronic device 200 or the second alignment angle of the second electronic device 200 with respect to the first electronic device 100 is within the first threshold range, the first electronic device 100 displays the device information of the second electronic device 200. The first electronic device 100 receives a second input of device information of the second electronic device 200 displayed on the first electronic device 100 from the user, and in response to the second input, the first electronic device 100 sends a request for establishing a bluetooth communication connection to the second electronic device 200. Therefore, the operation and time of the user for searching the second electronic device 200 in the device list can be reduced, the device connection and pairing can be performed in a more intuitive mode, and the user experience is improved.
