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

[0086] figure 1 Shown is a system frame diagram for implementing a Bluetooth throughput performance testing method in the present invention. The entire system structure is divided into five sub-modules: Bluetooth adapter, Bluetooth device to be tested, control unit, host, and wireless interference source. Among them, the control unit is a test device that integrates processing chips and displays, and requires USB and UART expansion interfaces, including control unit 1 and control unit 2. The host is connected to control unit 1 and control unit 2 through two USB data lines, and the control The unit 1 and the control unit 2 are respectively connected with the Bluetooth adapter and the Bluetooth device to be tested through a USB or UART interface.

[0087] In order to simulate the real use environment as much as possible, wireless transmission is used between the Bluetooth device to be tested and the Bluetooth adapter in the test, and the wireless interference environment is arti...

Embodiment 2

[0092] Based on the system frame diagram in Embodiment 1, this embodiment proposes a Bluetooth TX (transmit) throughput performance testing method, the program for executing the method is divided into a Client end and a Server end to run, and the Client end is sent as data And the role of control, the Server side as the role of data reception and processing. When evaluating the TX throughput performance of the Bluetooth device to be tested, the client-side program runs in the control unit 2, and the server-side program runs in the control unit 1. Wherein, before executing the test method, both the client program and the server program are copied on the control unit 1 and the control unit 2, and the test script running on the host is automatically performed on the control unit 1 and the control unit 2 according to the test case requirements. Select the appropriate role program (Client program or Server program) to execute, and the process flow chart is as follows figure 2 As ...

Embodiment 3

[0118] Based on the system frame diagram in Embodiment 1, this embodiment proposes a method for testing the RX throughput performance of a Bluetooth device. The difference from Embodiment 2 is that when testing the RX throughput performance of a Bluetooth device, the Bluetooth device to be tested serves as the data At the receiving end, the bluetooth adapter acts as the data sending end. When performing specific operations, the client program runs in the control unit 1, and the server program runs in the control unit 2.

[0119] Since the RX throughput performance test process is similar to the TX throughput performance test process in Embodiment 2, only the differences between the two are described in this embodiment, and the similarities are not repeated. The test flow chart is as follows Figure 5 shown.

[0120] In the test preparation stage, first start the Client program at one end of the Bluetooth adapter, read the MAC address of the Bluetooth adapter connected to the C...

Abstract

The invention relates to a method and a device for Bluetooth throughput performance production line test, which are suitable for, but not limited to, data transmission test under the connection of a Bluetooth adapter as an auxiliary test device and a device under test. The indicators such as throughput and packet loss rate of the Bluetooth device can be tested at the production stage of a factorywithout a professional test instrument, and the performance of the Bluetooth product is assessed by using a statistical method after the test is ended. The method and the device have the characteristics that a test platform is easy to set up, the test process does not require manual participation, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of performance testing, in particular to a method and device for testing Bluetooth throughput performance production lines. Background technique [0002] Bluetooth technology has been widely used in consumer electronics products. With the advancement of Bluetooth low power consumption technology, Bluetooth technology will be applied in a wider range of fields. Bluetooth audio is the most important field of Bluetooth technology application. With the improvement of people's pursuit of audio quality, the transmission bandwidth requirements of wireless audio devices are also getting higher and higher. The Android8.0 system can transmit Bluetooth data at a rate of up to 990kbps. Compared with the Android7.0 system Bluetooth transmission rate 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 testi...
