Description

Technical Field

[0001] The invention belongs to the field of network communications, and in particular to a method for visualizing the strength of a Bluetooth signal connected between a mobile phone and a telephone. Background Art

[0002] Bluetooth devices are common communication devices in daily life. Using Bluetooth to bind a mobile phone to an IP phone and using the IP phone as a Bluetooth device is one common use case for IP phones. However, when binding an IP phone to a mobile phone, the mobile phone may lose its connection to the IP phone for various reasons. The IP phone only displays the Bluetooth device connection status, but does not intuitively indicate the connection strength and stability. This makes it difficult to determine the stability of the connection between the IP phone and the mobile phone. This can also lead to sudden disconnections while the mobile phone is using the IP phone's functions. If the IP phone could display the connection strength and stability between the mobile phone and the IP phone in real time, problems caused by Bluetooth device disconnections could be avoided. Summary of the Invention

[0003] In order to solve the above problems existing in the prior art, the present invention provides a method for visualizing the Bluetooth signal strength of the connection between a mobile phone and a telephone, allowing customers to directly see the connection strength and stability of the Bluetooth device, reducing unpredictable disconnections between the telephone and the mobile phone during actual use.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] In one embodiment of the present invention, a method for visualizing the Bluetooth signal strength of a connection between a mobile phone and a telephone is proposed, the method comprising:

[0006] Use different models of mobile phones to bind to the phone;

[0007] The mobile phone changes its distance from the phone, and the phone host sends a command to obtain the Bluetooth signal strength value of the connection between the mobile phone and the phone to the Bluetooth module of the phone;

[0008] After receiving the command from the host phone, the Bluetooth module of the phone obtains the Bluetooth signal strength value of the connection between the mobile phone and the phone and returns it to the host phone;

[0009] The phone host sets the corresponding Bluetooth signal strength level according to the Bluetooth signal strength RSSI value returned by the Bluetooth module, and sends the corresponding phone LED light display status setting command to the microcontroller;

[0010] After receiving the command sent by the phone host, the microcontroller sets the display status of the corresponding phone LED light according to the Bluetooth signal strength level.

[0011] Furthermore, when the Bluetooth module has no return value, the Bluetooth signal strength level is set to 0, indicating disconnection; when the RSSI value returned by the Bluetooth module is <-65dbm, the Bluetooth signal strength level is set to 1, indicating low signal strength; when the RSSI value returned by the Bluetooth module is <-55dbm and ≥-65dbm, the Bluetooth signal strength level is set to 2, indicating medium signal strength; when the RSSI value returned by the Bluetooth module is ≥-55dbm, the Bluetooth signal strength level is set to 3, indicating high signal strength.

[0012] Furthermore, the phone host determines the final RSSI value by taking an average of three times according to the RSSI value returned by the Bluetooth module.

[0013] Furthermore, when the Bluetooth signal strength level is 0, the display status of the phone LED light is set to off; when the Bluetooth signal strength level is 1, the display status of the phone LED light is set to blue; when the Bluetooth signal strength level is 2, the display status of the phone LED light is set to red and blue; when the Bluetooth signal strength level is 3, the display status of the phone LED light is set to red.

[0018] Figure 1 This is a diagram showing the architecture of a method for visualizing the Bluetooth signal strength between a mobile phone and a telephone set according to the present invention;

[0019] Figure 2 It is a schematic diagram of the computer device structure of the present invention. DETAILED DESCRIPTION

[0020] The principles and spirit of the present invention will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are provided solely to enable those skilled in the art to better understand and implement the present invention, and are not intended to limit the scope of the present invention in any way. Rather, these embodiments are provided to make this disclosure more thorough and complete, and to fully convey the scope of the present disclosure to those skilled in the art.

[0021] Those skilled in the art will appreciate that the embodiments of the present invention may be implemented as a system, apparatus, device, method, or computer program product. Therefore, the present disclosure may be implemented in the following forms: entirely in hardware, entirely in software (including firmware, resident software, microcode, etc.), or in a combination of hardware and software.

[0022] This invention aims to find a method that uses a combination of software and hardware to intuitively display the Bluetooth signal strength (stability) of the connection between a mobile phone and a telephone, thereby providing users with a direct view of the Bluetooth device connection status. This method optimizes the display of Bluetooth connection status, reduces unpredictable disconnections between the mobile phone and the telephone during actual use, and makes the scene more intuitive.

[0023] The basic idea of ​​the present invention is to use a Bluetooth module to obtain the Bluetooth signal strength of the connection between a mobile phone and a telephone. In an office (unobstructed) environment, different mobile phones (Apple, Huawei, Samsung, etc.) are used to bind the telephone. The distance between the telephone and the mobile phone is changed by moving the mobile phone. The distance between the mobile phone and the telephone and the Bluetooth signal strength (RSSI) value of the connection between the mobile phone and the telephone obtained by the Bluetooth module are printed and displayed in the work log under the distance. The Bluetooth signal strength level is set by comprehensively considering the data collected under different situations, and the display status of the telephone LED light corresponding to the different levels is set. The telephone host sends a telephone LED light display status setting command (switch and color) to the microcontroller to set the telephone LED light status, thereby achieving the purpose of intuitively visualizing the Bluetooth connection signal strength.

[0024] The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0025] Figure 1 This is a diagram showing the architecture of the method for visualizing the Bluetooth signal strength between a mobile phone and a telephone. Figure 1 As shown, the specific steps of the method are as follows:

[0026] Bind your phone and mobile phone: Turn on the Bluetooth search mode on both your phone and mobile phone, find your phone in the search list on the mobile phone, select it and confirm to complete the binding of the phone and mobile phone.

[0027] The mobile phone changes its distance from the phone. At the same time, the phone host sends an HCI command (to obtain the RSSI value of the Bluetooth signal strength between the mobile phone and the phone) to the Bluetooth chip (AMPAK AP6256) of the phone's Bluetooth module (BTWDB01) through the UART port, and receives the command return value.

[0028] After receiving the command from the phone host, the Bluetooth module of the phone obtains the Bluetooth signal strength value of the connection between the mobile phone and the phone and returns it to the phone host.

[0029] The phone sets the corresponding Bluetooth signal strength level based on the RSSI value returned by the Bluetooth module. If the Bluetooth module returns no value, the Bluetooth signal strength level is set to 0, indicating a disconnection. If the RSSI value returned by the Bluetooth module is less than -65dBm, the Bluetooth signal strength level is set to 1, indicating low signal strength. If the RSSI value returned by the Bluetooth module is less than -55dBm and greater than or equal to -65dBm, the Bluetooth signal strength level is set to 2, indicating medium signal strength. If the RSSI value returned by the Bluetooth module is greater than or equal to -55dBm, the Bluetooth signal strength level is set to 3, indicating high signal strength. Due to the fluctuating nature of Bluetooth signal strength, the phone determines the final RSSI value by taking the average of three measurements (at 200ms intervals).

[0030] The phone host will send the signal to the Bluetooth 2 C communication bus sends the corresponding phone LED light display status setting command to the microcontroller (PIC16F15354).

[0031] After receiving commands from the phone host, the microcontroller sets the corresponding phone LED display status through the ICSP interface. When the Bluetooth signal strength level is 0, the phone LED display status is set to off; when the Bluetooth signal strength level is 1, the phone LED display status is set to blue; when the Bluetooth signal strength level is 2, the phone LED display status is set to red and blue; when the Bluetooth signal strength level is 3, the phone LED display status is set to red.

[0032] It should be noted that although the operations of the method of the present invention are described in a specific order in the above embodiments and drawings, this does not require or imply that these operations must be performed in this specific order, or that all illustrated operations must be performed to achieve the desired results. Additionally or alternatively, certain steps may be omitted, multiple steps may be combined into one step, and / or one step may be broken down into multiple steps.

[0033] In order to more clearly explain the above-mentioned method of visualizing the Bluetooth signal strength of the connection between the mobile phone and the telephone, a specific embodiment is used for illustration below. However, it should be noted that this embodiment is only for better illustrating the present invention and does not constitute an improper limitation to the present invention.

[0034] Example:

[0035] When the Bluetooth signal is clear, bind the phone to the Samsung FlipZ. The phone will indicate successful binding. Because the binding is close (less than 1 meter), the ring LED light will turn red. This indicates that the connection signal between the phone and the phone is strong and stable.

[0036] Keep increasing the distance between your phone and the handset. When the straight-line distance between the phone and the handset reaches about 10 meters, the ring-shaped LED light on the handset will alternate between red and blue. This indicates that the signal strength between the phone and the handset is moderate and the connection is stable.

[0037] Continue to increase the distance between the phone and the handset. When the straight-line distance between the phone and the handset reaches about 15 meters, the ring-shaped LED light on the handset will turn blue. This indicates that the connection signal strength between the phone and the handset is weak, unstable, and easily disconnected.

[0038] Continue to increase the distance between the mobile phone and the phone. When the straight-line distance between the mobile phone and the phone reaches 20 meters, the ring LED light on the phone goes out and the mobile phone and the phone are disconnected.

[0039] Based on the above invention concept, Figure 2 As shown, the present invention also proposes a computer device 100, including a memory 110, a processor 120 and a computer program 130 stored in the memory 110 and executable on the processor 120. When the processor 120 executes the computer program 130, the method for visualizing the Bluetooth signal strength of the connection between the mobile phone and the telephone is implemented.

[0040] Based on the aforementioned inventive concept, the present invention further proposes a computer-readable storage medium storing a computer program for executing the aforementioned method for visualizing the Bluetooth signal strength of the connection between a mobile phone and a telephone.

[0041] The method for intuitively displaying the Bluetooth connection signal strength (stability) between a mobile phone and a telephone proposed by the present invention greatly avoids the unpredictable disconnection of the mobile phone and the telephone.

[0042] Although the spirit and principles of the present invention have been described with reference to several specific embodiments, it should be understood that the present invention is not limited to the specific embodiments disclosed, and the division into various aspects does not mean that the features of these aspects cannot be combined to benefit. Such division is only for the convenience of expression. The present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

[0043] Regarding the limitation of the protection scope of the present invention, those skilled in the art should understand that, based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the protection scope of the present invention.
