Bluetooth test system and method

The present invention relates to a test system and method, and more particularly to a Bluetooth test system and method.

Bluetooth technology is a short-range radio technology that is an open and uniform standard for global voice and data transmission. It is designed to replace data cables and enable any compatible portable and fixed devices. Low-power, low-cost, short-range wireless connectivity is possible. This technology works in the global open 2.4GHz ISM frequency band. Based on the wireless circuit that improves the fast and reliable transmission of voice and data information, it uses frequency hopping technology to improve anti-interference and anti-attenuation performance. Its RF part adopts Gaussian frequency shift keying (GFSK). )Modulation. It provides 23 or 79 channels, each with a width of 1MHz. According to the transmission power of the radio frequency part, the existing Bluetooth devices are generally divided into three levels, and the commonly used one is a level, and the transmission power is about 0 dBm, and the transmission distance is up to 10 meters. Using Bluetooth technology, you can make a variety of data and voice devices in your home or office into a pico-net. You can also use mobile phones to control devices such as photocopiers and fax machines in the office. The use and development of Bluetooth technology has greatly promoted the improvement of human life quality and office conditions.

There are nearly 500 Bluetooth devices released in the world. According to the requirements of the SIG, any company that manufactures or sells Bluetooth devices must first sign the Bluetooth protocol to become a member of the Bluetooth organization and then prove that its products comply with the Bluetooth system specifications. Its products must It must be verified one by one according to the Bluetooth device test specification, and the qualified products can be included in the Bluetooth organization agreement. Therefore, testing Bluetooth devices has become an indispensable step in the market.

The test uses a wireless interface to perform boot operations locally or to perform boot operations locally using a software (or hardware) interface. When a boot operation is performed locally using a software (or hardware) interface, a Paging scan and an Inquiry scan are performed until a connection to the Bluetooth test instrument is established. The query scan needs to find the electronic device to be tested, and an additional data string cycle is needed to collect all the responses. Taking the mobile phone as an example, when the mobile phone is shipped from the factory, most of the internal address of the mobile phone is the same. Performing paging scanning and query scanning will inevitably waste a lot of testing time.

In view of the above, it is necessary to provide a Bluetooth test system and method, which can effectively save test time.

In step S32, the mask box 3 is closed, and the detecting module 12 detects whether the mask box 3 is closed. If the mask box 3 is closed, the mask box 3 sends a command to the detecting module 12, and the detecting module 12 receives the command to indicate that the mask box 3 has been closed.

Step S34, after the hood 3 is closed, the opening module 14 sends an AT (Attention) command to the electronic device 4 to be tested, and the Bluetooth function of the electronic device 4 to be tested is turned on, so that the electronic device 4 to be tested enters. Test mode.

In step S36, the Bluetooth tester 2 performs a paging scan on the electronic device 4 to be tested, and establishes a connection between the electronic device 4 to be tested and the Bluetooth tester 2.

Step S38, after the Bluetooth tester 2 is connected to the electronic device 4 to be tested, the Bluetooth tester 2 performs a Bluetooth test on the electronic device 4 to be tested.

In step S40, after the Bluetooth tester 2 tests the electronic device 4 to be tested, the test end command is sent to the receiving module 16.

Step S42, after receiving the Bluetooth test end instruction, the receiving module 16 sends out The sending module 18 sends the test parameters that need to be acquired to the Bluetooth tester 2. The test parameters include: a bit error rate, a radio frequency power value, and the like.

In step S44, the receiving module 16 receives the test parameter value fed back by the Bluetooth tester 2.

In step S46, the storage module 22 stores the test result in the database 8 and presents it to the tester in the form of a table, the contents of the table include: test project, Bluetooth technical specification, test parameter value, test time and Test version, etc.

In step S48, the determining module 20 determines whether the received test parameter value is qualified according to the Bluetooth technical specification. If it is qualified, the process is terminated; if it is not, then the process returns to step S32, and the test is repeated. If the second test result still does not meet the Bluetooth technical specification, the test of the electronic device 4 to be tested is terminated.
