[0002] In the field of smart home IoT, a large number of smart devices use the BLE (Bluetooth Low Energy) protocol. BLE is a short-range wireless communication technology based on the 2.4GHz ISM band. At the same time, other protocols such as Wi-Fi and ZigBee may also communicate on the 2.4GHz band, which may interfere with BLE communication. Physical objects, such as walls and metal objects, can also affect BLE communication. Detecting the communication quality of smart devices in the BLE network helps to discover problems and optimize local network topology.

[0003] Existing technologies for testing the communication quality of smart devices in BLE networks typically require specialized testing equipment and cannot detect communication latency, resulting in poor testing efficiency and effectiveness.

[0004] Therefore, it is necessary to propose a solution to improve the efficiency and effectiveness of communication quality detection. Summary of the Invention

[0016] The communication delay time is calculated based on the first statistical result, and the packet error rate is calculated based on the second statistical result; and / or, the first statistical result and the second statistical result are reported to the cloud platform so that the cloud platform can calculate the communication delay time based on the first statistical result and the packet error rate based on the second statistical result.

[0017] In one embodiment, the step of calculating the communication delay time based on the first statistical result includes:

[0018] Calculate the difference between the sending time of the detection packet and the receiving time of the acknowledgment receipt corresponding to each detection count to obtain each delay time;

[0022] Subtract the total number of packets sent from the number of times acknowledgment receipts were received to obtain the number of erroneous packets;

[0023] The packet error rate is obtained by dividing the number of erroneous packets by the total number of packets sent.

[0024] Furthermore, to achieve the above objectives, this application also proposes a communication quality detection method, which is applied to at least one low-power Bluetooth sub-device, and the method includes:

[0025] Receive detection data sent by a Bluetooth Low Energy gateway, wherein the detection data is sent by the Bluetooth Low Energy gateway in response to receiving a detection command, according to the detection command;

[0026] A confirmation receipt corresponding to the detection data is generated and sent to the Bluetooth Low Energy gateway, so that the Bluetooth Low Energy gateway receives the confirmation receipt and generates or determines the detection result corresponding to the at least one Bluetooth Low Energy sub-device based on the confirmation receipt and the detection data, wherein the detection result includes communication latency and packet error rate.

[0049] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0050] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of this application embodiment is as follows: Upon receiving a detection command, the Bluetooth Low Energy (BLE) gateway sends detection data to at least one BLE sub-device according to the detection command; receives an acknowledgment from at least one BLE sub-device; and generates or determines a detection result corresponding to at least one BLE sub-device based on the acknowledgment and detection data. The detection result includes communication latency and packet error rate. This solution does not require specialized detection equipment and can detect the communication latency of at least one BLE sub-device, thereby improving communication quality detection efficiency and detection effectiveness.

[0052] Technical terms used in the embodiments of this application:

[0053] BLE: Bluetooth Low Energy;

[0054] DTM: Direct Test Mode, defined in the Bluetooth core specification.

[0055] In this embodiment, for ease of description, the following description uses a communication quality detection device as the execution subject.

[0056] In the field of smart home IoT, a large number of smart devices use the BLE protocol. BLE is a short-range wireless communication technology based on the 2.4GHz ISM band. At the same time, other protocols such as Wi-Fi and ZigBee may also communicate on the 2.4GHz band, which may interfere with BLE communication. Physical objects, such as walls and metal objects, can also affect BLE communication. Detecting the communication quality of smart devices in the BLE network helps to discover problems and optimize local network topology.

[0057] The Bluetooth core specification defines a mode called DTM for Bluetooth radio frequency performance testing. All standard Bluetooth devices implement this mode, which is mainly used in the research and development and production stages.

[0058] Reference Figure 1 , Figure 1 This is a schematic diagram of the detection principle in existing technology, such as... Figure 1 As shown, the existing testing process includes three devices:

[0059] DUT (Device Under Test) refers to the device under test;

[0060] Upper Tester refers to the host computer testing equipment, which is usually a PC;

[0061] Lower Tester refers to the lower-level testing equipment, which is generally a professional Bluetooth RF testing device.

[0062] The Upper Tester connects to the DUT via a serial port. The Upper Tester sends test commands, the DUT executes the specified operations, and returns the specified results.

[0063] The Lower Tester receives signals from the DUT or sends signals to the DUT and generates a report.

[0064] Reference Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of the sending test process in the existing technology. Figure 3 This is a schematic diagram of the receiving test process in the prior art, such as... Figure 2 and Figure 3 As shown, the sending and receiving test processes are generally the same, mainly including:

[0065] 1. The Upper Tester sends commands to the DUT to perform transmit or receive tests;

[0066] 2. Upon receiving the instruction, the DUT sends a receipt to the Upper Tester;

[0067] 3. The DUT begins sending or receiving data packets;

[0068] 4. The Upper Tester sends a command to the DUT to end the test;

[0069] 5. The DUT sends a test receipt to the Upper Tester.

[0070] Therefore, it can be seen that the existing detection methods have the following drawbacks:

[0071] 1. The BLE device needs to be running in DTM mode, and it cannot respond to other normal operations during detection;

[0072] 2. Dedicated Bluetooth RF testing equipment is required for testing;

[0073] 3. Unable to detect communication delay time.

[0074] This application provides a solution that can measure the latency of BLE sub-devices in the current BLE networking environment without modifying the BLE sub-devices or using additional testing equipment, and can send testing commands from the cloud.

[0075] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device or communication quality detection device capable of performing the above functions. The following description uses a communication quality detection device as an example to illustrate this embodiment and the subsequent embodiments.

[0076] Based on this, embodiments of this application provide a communication quality detection method, referring to... Figure 4 , Figure 4 This is a flowchart illustrating the first embodiment of the communication quality detection method of this application.

[0077] In this embodiment, the communication quality detection method includes steps S10 to S30:

[0078] Step S10: In response to receiving a detection command, send detection data to at least one Bluetooth Low Energy sub-device according to the detection command;

[0079] Specifically, compared to existing technologies that can only issue detection commands through a host computer (such as a computer), this embodiment of the application sends detection commands to the BLE gateway through a cloud platform, making the detection method more flexible.

[0080] Optionally, after receiving the detection command sent by the cloud platform, the BLE gateway can send detection data to at least one Bluetooth Low Energy (BLE) sub-device according to the detection command. In this embodiment, detection data can be sent to multiple BLE sub-devices simultaneously, thereby realizing the detection of the communication quality of multiple BLE sub-devices and improving the efficiency of communication quality detection.

[0081] Step S20: Receive an acknowledgment from the at least one Bluetooth Low Energy sub-device;

[0082] Furthermore, after the BLE gateway sends detection data to at least one Bluetooth Low Energy (BLE) sub-device according to the detection command, under normal circumstances, at least one BLE sub-device will generate and return a corresponding acknowledgment receipt, i.e., an ACK receipt, and the BLE gateway can then receive the acknowledgment receipt sent by at least one BLE sub-device.

[0083] Optionally, in the BLE protocol stack, the link layer has a mechanism for timeout retransmission, verification, and judgment of data packets. The core process here is that the sending device performs CRC verification on the data when sending it, and the receiving device also performs CRC verification on the data when receiving it. If the CRC verification matches, the receiving device will send an ACK receipt for the data packet. The key detection indicators in this embodiment rely on monitoring the data packets of the BLE link layer. In order to prevent processing too many irrelevant data packets, only the detection-related packets are selected for processing.

[0084] Step S30: Based on the confirmation receipt and the detection data, generate or determine the detection result corresponding to the at least one low-power Bluetooth sub-device, wherein the detection result includes communication latency and packet error rate.

[0085] Furthermore, after receiving an acknowledgment from at least one Bluetooth Low Energy (BLE) sub-device, the BLE gateway can generate or determine the detection result corresponding to the at least one BLE sub-device based on the acknowledgment and the detection data. The detection result includes communication latency and packet error rate.

[0086] Optionally, in this embodiment of the application, the BLE gateway can perform statistics based on the sent detection data and the received confirmation receipts to obtain relevant statistical results.

[0087] As one implementation method, the BLE gateway can directly calculate the corresponding communication latency and packet error rate based on the statistical results, and then report the communication latency and packet error rate as detection results to the cloud platform.

[0088] As another implementation method, the BLE gateway can report the statistical results to the cloud platform, thereby using the computing power of the cloud platform to calculate the communication latency and packet error rate as the final detection result.

[0089] In this embodiment, the Bluetooth Low Energy (BLE) gateway, upon receiving a detection command, sends detection data to at least one BLE sub-device; receives an acknowledgment from at least one BLE sub-device; and generates or determines a detection result corresponding to at least one BLE sub-device based on the acknowledgment and detection data. The detection result includes communication latency and packet error rate. This solution eliminates the need for specialized detection equipment and can detect the communication latency of at least one BLE sub-device, thereby improving communication quality detection efficiency and effectiveness.

[0090] Based on the first embodiment of this application, a second embodiment of this application is proposed. In this second embodiment, content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to... Figure 5 Step S10 also includes steps S101 to S103:

[0091] S101: Determine the number of tests and the size of the test package according to the test instruction;

[0092] S102: According to the number of detections and the size of the detection packet, send the corresponding detection packet to the at least one low-power Bluetooth sub-device at the attribute layer;

[0093] S103: If the detection packet transmission times out, the detection packet is retransmitted to at least one corresponding Bluetooth Low Energy sub-device.

[0094] Reference Figure 6 , Figure 6 This is a schematic diagram of the interaction timing according to the second embodiment of this application, as shown below. Figure 6 As shown, the cloud platform sends a start detection command to the BLE gateway. The command includes the number of detections and the size of the detection packet. To avoid the detection packet being too large and causing the detection packet to be split during subsequent transmission, which would affect the accuracy of the final statistical results, the maximum size of the detection packet is set to 20 bytes in this embodiment. In other embodiments, the threshold for the size of the detection packet can be set according to the actual situation. This embodiment does not constitute a specific limitation on this.

[0095] Optionally, the BLE gateway can enter detection mode after receiving the detection command sent by the cloud platform. Only after entering detection mode will it begin to process the detection packets and ACK receipts of the BLE link layer.

[0096] Optionally, the BLE gateway sends detection data to the BLE sub-device at the BLE protocol ATT (Attribute) layer according to the number of detections and the size of the detection packets issued by the cloud platform.

[0097] For example, the ATT layer uses a Handle value of 65535. The first byte of the detection data is 'a', and each subsequent byte value is incremented by 1 based on the ASCII code of the previous byte. For instance, a 10-byte detection packet might contain the string "abcdefghij". The ATT layer's Handle is 2 bytes long, and 65535 is the maximum value that 2 bytes can represent. Devices start using Handles from 1, so using the maximum value will not result in any unused Handles. Devices will receive unused Handles normally, but will receive an ATT layer error message indicating an incorrect Handle, similar to "Invalid Handle". However, this does not affect packet transmission and ACK sending at the link layer.

[0098] Optionally, the BLE sub-device sends an acknowledgment receipt for the detection data packet at the link layer.

[0099] Optionally, the BLE gateway generates a corresponding timestamp when sending the detection packet, which can also be understood as starting a corresponding timer. If a confirmation acknowledgment is not received after a preset time (e.g., 2 seconds), it can be considered a timeout. The BLE link layer will automatically trigger a retransmission mechanism to resend the corresponding detection packet. It should be noted that the retransmitted detection packet should also be included in the statistics of the total number of packets sent.

[0100] This embodiment, through the above-described scheme, specifically determines the number of detections and the size of the detection packet according to the detection instruction; according to the number of detections and the size of the detection packet, the corresponding detection packet is sent to the at least one Bluetooth Low Energy (BLE) sub-device at the attribute layer; if the detection packet transmission times out, the detection packet is retransmitted to the corresponding at least one BLE sub-device. This enables the cloud platform to instruct the BLE gateway to send detection data to at least one BLE sub-device, facilitating subsequent result statistics and obtaining the detection results of at least one BLE sub-device. It eliminates the need for specialized detection equipment and can detect the communication latency of at least one BLE sub-device, thereby improving the efficiency and effectiveness of communication quality detection.

[0101] Based on any of the foregoing embodiments of this application, a third embodiment of this application is proposed. In this third embodiment, any content that is the same as or similar to any of the foregoing embodiments can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 7 Step S30 also includes steps S301 to S302:

[0102] S301: Calculate the sending time of the detection packet and the receiving time of the acknowledgment receipt for each detection count to obtain the first statistical result; and calculate the number of detection packets sent, the number of retransmissions, and the number of acknowledgment receipts received to obtain the second statistical result.

[0103] S302: Calculate the communication delay time based on the first statistical result, and calculate the packet error rate based on the second statistical result; and / or, report the first statistical result and the second statistical result to the cloud platform, so that the cloud platform can calculate the communication delay time based on the first statistical result and calculate the packet error rate based on the second statistical result.

[0104] Optionally, the step of calculating the communication delay time based on the first statistical result includes:

[0105] Calculate the difference between the sending time of the detection packet and the receiving time of the acknowledgment receipt corresponding to each detection count to obtain each delay time;

[0106] The communication delay time is obtained by summing and averaging the delay times based on the number of detections.

[0107] Optionally, the step of calculating the packet error rate based on the second statistical result includes:

[0108] Add the number of times the detection packets were sent to the number of retransmissions to obtain the total number of packets sent;

[0109] Subtract the total number of packets sent from the number of times acknowledgment receipts were received to obtain the number of erroneous packets;

[0110] The packet error rate is obtained by dividing the number of erroneous packets by the total number of packets sent.

[0111] Specifically, in this embodiment of the application, the BLE gateway can perform statistics based on the sent detection data and the received confirmation receipts to obtain relevant statistical results.

[0112] As one implementation method, the BLE gateway can directly calculate the corresponding communication latency and packet error rate based on the statistical results, and then report the communication latency and packet error rate as detection results to the cloud platform.

[0113] As another implementation method, the BLE gateway can report the statistical results to the cloud platform, thereby using the computing power of the cloud platform to calculate the communication latency and packet error rate as the final detection result.

[0114] Optionally, the BLE gateway reports the latency and timeout status of the current detection to the cloud platform. When all detection attempts are completed, the BLE gateway exits the detection mode.

[0115] Optionally, the BLE gateway reports the final detection results to the cloud platform, such as the number of packets sent, communication latency, and packet error rate.

[0116] Optionally, the communication delay time can be measured as: the time it takes for the BLE gateway to receive the ACK receipt – the time it takes for the BLE gateway to send the data packet.

[0117] Optionally, the packet error rate can be measured as: (total number of packets sent - number of times ACK receipts were received) ÷ total number of packets sent.

[0118] This embodiment, through the above-described scheme, specifically obtains a first statistical result by statistically analyzing the sending time of the detection packets and the receiving time of the acknowledgment receipts corresponding to each detection count; and obtains a second statistical result by statistically analyzing the number of detection packets sent, the number of retransmissions, and the number of acknowledgment receipts received; calculates the communication delay time based on the first statistical result, and calculates the packet error rate based on the second statistical result; and / or, reports the first and second statistical results to the cloud platform, so that the cloud platform can calculate the communication delay time based on the first statistical result and the packet error rate based on the second statistical result. This method requires no modification to the BLE sub-device, no additional detection equipment, and can measure the communication delay time of the BLE sub-device in the current BLE network environment by issuing detection commands or calculating results through the cloud, thereby improving the efficiency and effectiveness of communication quality detection.

[0119] This application also provides a communication quality detection method, applied to at least one low-power Bluetooth sub-device, as described above. Figure 8 , Figure 8 This is a flowchart illustrating the fourth embodiment of the communication quality detection method of this application.

[0120] In this embodiment, the communication quality detection method includes steps A10 to A20:

[0121] Step A10: Receive detection data sent by the Bluetooth Low Energy gateway, wherein the detection data is sent by the Bluetooth Low Energy gateway in response to receiving a detection command, according to the detection command;

[0122] Step A20: Generate an acknowledgment receipt corresponding to the detection data and send the acknowledgment receipt to the Bluetooth Low Energy gateway, so that the Bluetooth Low Energy gateway receives the acknowledgment receipt and, based on the acknowledgment receipt and the detection data, generates or determines the detection result corresponding to the at least one Bluetooth Low Energy sub-device, wherein the detection result includes communication latency and packet error rate.

[0123] Specifically, compared to existing technologies that can only issue detection commands through a host computer (such as a computer), this embodiment of the application sends detection commands to the BLE gateway through a cloud platform, making the detection method more flexible.

[0124] Optionally, after receiving the detection command sent by the cloud platform, the BLE gateway can send detection data to at least one Bluetooth Low Energy (BLE) sub-device according to the detection command. In this embodiment, detection data can be sent to multiple BLE sub-devices simultaneously, thereby realizing the detection of the communication quality of multiple BLE sub-devices and improving the efficiency of communication quality detection.

[0125] Furthermore, after the BLE gateway sends detection data to at least one Bluetooth Low Energy (BLE) sub-device according to the detection command, under normal circumstances, at least one BLE sub-device will generate and return a corresponding acknowledgment receipt, i.e., an ACK receipt, and the BLE gateway can then receive the acknowledgment receipt sent by at least one BLE sub-device.

[0126] Optionally, in the BLE protocol stack, the link layer has a mechanism for timeout retransmission, verification, and judgment of data packets. The core process here is that the sending device performs CRC verification on the data when sending it, and the receiving device also performs CRC verification on the data when receiving it. If the CRC verification matches, the receiving device will send an ACK receipt for the data packet. The key detection indicators in this embodiment rely on monitoring the data packets of the BLE link layer. In order to prevent processing too many irrelevant data packets, only the detection-related packets are selected for processing.

[0127] Furthermore, after receiving an acknowledgment from at least one Bluetooth Low Energy (BLE) sub-device, the BLE gateway can generate or determine the detection result corresponding to the at least one BLE sub-device based on the acknowledgment and the detection data. The detection result includes communication latency and packet error rate.

[0128] Optionally, in this embodiment of the application, the BLE gateway can perform statistics based on the sent detection data and the received confirmation receipts to obtain relevant statistical results.

[0129] As one implementation method, the BLE gateway can directly calculate the corresponding communication latency and packet error rate based on the statistical results, and then report the communication latency and packet error rate as detection results to the cloud platform.

[0130] As another implementation method, the BLE gateway can report the statistical results to the cloud platform, thereby using the computing power of the cloud platform to calculate the communication latency and packet error rate as the final detection result.

[0131] In this embodiment, through the above-described scheme, at least one Bluetooth Low Energy (BLE) sub-device receives detection data sent by a BLE gateway. The BLE gateway, in response to a received detection command, sends the detection data according to the command. It then generates a confirmation receipt corresponding to the detection data and sends the confirmation receipt to the BLE gateway. The BLE gateway receives the confirmation receipt and, based on the confirmation receipt and the detection data, generates or determines a detection result for the at least one BLE sub-device. The detection result includes communication latency and packet error rate. This method eliminates the need for specialized detection equipment and can detect the communication latency of at least one BLE sub-device, thereby improving the efficiency and effectiveness of communication quality detection.

[0132] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the communication quality detection method of this application.

[0136] The determination module is used to generate or determine the detection result corresponding to the at least one low-power Bluetooth sub-device based on the confirmation receipt and the detection data, wherein the detection result includes communication latency and packet error rate.
