Problems solved by technology

[0004] In the existing schemes, the throughput performance evaluation method applied in the Bluetooth factory test has not been proposed. Some schemes propose to use the Bluetooth signal strength RSSI value to obtain the output power and sensitivity of the Bluetooth antenna, but there is a lack of Bluetooth throughput and packet loss performance evaluation. method

Embodiment 1

[0043] figure 1 Shown is a system framework diagram for implementing a Bluetooth throughput performance test method of the present invention. The entire system structure is divided into five sub-modules: Bluetooth adapter, Bluetooth device to be tested, control unit, PC host, and wireless interference source. Among them, the control unit is a test device that integrates processing chips and displays. It requires USB and UART expansion interfaces, including control unit 1 and control unit 2. The PC host is connected to control unit 1 and control unit 2 through two USB data lines. The control unit 1 and the control unit 2 are respectively connected to the Bluetooth adapter and the Bluetooth device to be tested through a USB or UART interface.

[0044] In order to simulate the real use environment as much as possible, wireless transmission is used between the Bluetooth device under test and the Bluetooth adapter in the test, and the wireless interference environment is artificially c...

Embodiment 2

[0049] Based on the system framework diagram in the first embodiment, this embodiment proposes a Bluetooth TX (transmit) throughput performance test method. The program used to execute the method is divided into the client side and the server side to run, and the client side is used as data transmission And the role of control, the server side as the role of data receiving and processing. When evaluating the TX throughput performance of the Bluetooth device under test, the client program runs in the control unit 2, and the server program runs in the control unit 1. Among them, before executing the test method, copy both the Client-side program and the Server-side program on the control unit 1 and the control unit 2, and the test script running on the PC host is on the control unit 1 and the control unit 2 according to the test case requirements Automatically select the appropriate role program (Client program or Server program) for execution, the process flow chart is as follow...

Embodiment 3

[0075] Based on the system framework diagram in the first embodiment, this embodiment proposes a method for testing the RX throughput performance of a Bluetooth device. The difference from the second embodiment is that when testing the RX throughput performance of the Bluetooth device, the Bluetooth device under test serves as the data At the receiving end, the Bluetooth adapter serves as the data sending end. When implementing specific operations, the client program is run in the control unit 1, and the server program is run in the control unit 2.

[0076] Since the RX throughput performance test process is similar to the TX throughput performance test process in the second embodiment, only the differences between the two are described in this embodiment, and the similarities will not be repeated. The test flow chart is as follows: Figure 5 Shown.

[0077] In the test preparation phase, first start the Client program on the Bluetooth adapter, read the MAC address of the Bluetooth ...

Abstract

The invention relates to a Bluetooth device performance testing system, which is suitable for, but not limited to, using a Bluetooth adaptor as an auxiliary test device to build connection data transmission test with a to-be-tested device, wherein test of indicators, such as throughput rate and packet loss rate, of the Bluetooth device can be finished in a factory production stage without professional instruments, and after test, estimation on performance of the Bluetooth products is realized through a statistical method. The system provided by the invention has the characteristics that the testing system is convenient to establish, artificial participation is not needed for a test process, production efficiency is improved, and in the test process, by setting a packet mask attribute and an auto-flush mechanism on a connection link, a test result can be more accurate and reliable.

Description

Technical field [0001] The invention relates to the field of performance testing, in particular to a Bluetooth device performance testing system. Background technique [0002] Bluetooth technology has been widely used in consumer electronic products. With the advancement of low-power Bluetooth technology, Bluetooth technology will be applied in a wider range of fields. Bluetooth audio is the most important field for the application of Bluetooth technology. With the improvement of people’s pursuit of audio and sound quality, the requirements for the transmission bandwidth of wireless audio devices are also getting higher and higher. The Android8.0 system’s Bluetooth data transmission rate is as high as 990kbps. Compared with the Android7.0 system, the Bluetooth transmission rate is increased by 3 times. [0003] At present, the production test of Bluetooth products is divided into semi-finished product test and finished product test. Semi-finished product testing generally focuses...
