Example one
Referring to fig. 1, an embodiment of the present invention provides a factory test pairing method for VR devices, including the following operation steps:
step 100: generating an independent and unique SN code for each VR controller;
step 200: generating corresponding wireless communication parameters according to a preset protocol by aiming at a VR controller through a unique SN code of the VR controller, and writing the wireless communication parameters into the VR controller; generating a two-dimensional code label according to the SN code, and attaching the two-dimensional code label to the surface of the equipment of the VR controller;

And then, the upper computer acquires the wireless communication parameters of the VR controller, and after the wireless communication parameters are input into the upper computer, the wireless communication parameters stored by the VR controller are the same as the wireless communication parameters analyzed by the upper computer, so that the wireless communication between the upper computer and the VR controller is established according to the wireless communication parameters.
Through the factory test pairing method of the VR equipment, the upper computer and the VR controller can be quickly matched and connected in wireless communication, and finally, the test work can be smoothly completed, so that the complexity of a factory test system can be effectively avoided, and the test convenience is provided.
The following detailed description is provided for a specific technical scheme and a specific technical effect of the factory test pairing method for VR devices in this embodiment:
in a specific embodiment, the VR controller includes a first Nordic chip; in step 200, the wireless communication parameters are written into the VR controller, specifically the following operations: the wireless communication parameters are written to a first Nordic chip of the VR controller.
In a specific embodiment, referring to fig. 2, the upper computer includes an upper computer body and a second Nordic chip, and the second Nordic chip of the upper computer communicates with the upper computer body through a serial port interface; in step 400, the upper computer obtains the wireless communication parameters of the VR controller, and after the wireless communication parameters are input to the upper computer, the wireless communication parameters stored by the VR controller are the same as the wireless communication parameters analyzed by the upper computer, so as to establish the wireless communication between the upper computer and the VR controller according to the wireless communication parameters, specifically comprising the following operation steps:

step 420: the wireless communication parameters in the second Nordic chip of the upper computer are the same as the wireless communication parameters stored in the first Nordic chip of the VR controller;
step 430: and finally, establishing wireless communication connection with the first Nordic chip of the VR controller through the second Nordic chip of the upper computer, so that the communication connection between the upper computer body and the VR controller is realized.
It should be noted that the VR controller includes a Nordic module, which is a wireless communication module. And the Nordic module at the VR controller end and the Nordic module at the upper computer end establish wireless communication connection for data transmission through a Gazell communication protocol. And the Nordic module at the upper computer end is communicated with the upper computer through a serial port interface, so that an information channel is established between the VR controller and the upper computer.
In a specific embodiment, the second Nordic chip of the upper computer is in wireless communication connection with the first Nordic chip of the VR controller through a private communication protocol; the private communication protocol is a 2.4Ghz private communication protocol.
It should be noted that, in the factory test pairing method for VR devices in this embodiment, private protocol communication is used, and general protocol communication is not used, so that communication is more secure and reliable. In addition, in the factory test process, excessive application does not need to be installed, and the factory test efficiency can be effectively improved.
In a specific embodiment, the second Nordic chip of the upper computer and the first Nordic chip of the VR controller are in wireless communication connection through a Gazell communication protocol.
It should be noted that, in the factory test pairing method for VR devices in this embodiment, multiple forms of proprietary protocol communication may be adopted, but the Gazell communication protocol may be adopted in the preferred technical solution; in this embodiment, the VR controller establishes a wireless communication connection with the Nordic chip of the host computer by using the Gazell communication protocol on the Nordic chip, and the reason for this is as follows: the tracking function of the VR controller gives the user a better experience if it has the technical advantage of low latency and high accuracy. The technical advantages of low delay and high precision are achieved, and the VR controller is required to upload IMU information of the VR controller to the all-in-one machine at high frequency. But if the bluetooth 5.0 communication protocol is used, the above advantages cannot be achieved. However, the Gazell protocol in this embodiment is adopted to meet VR product requirements. The Gazell communications protocol described above is a 2.4Ghz proprietary communications protocol provided by Nordic corporation. The wireless communication parameters included in this example are mainly of the following two types: a communication address and a communication band list.
Regarding the communication address: the SN code is composed of M-bit characters, and the last N bits of the SN code are taken as the Gazell communication address;
with respect to the list of communication bands: the communication frequency band list is a list consisting of N signal channel frequency bands and uses A signal channels for communication; and taking the last N numbers of the SN code, and dividing the last N numbers by the Gazell bandwidth number C to obtain an offset parameter, wherein the frequency band of each signal channel is (C/A × i) + B, i is 0-A-1.
For example, the following steps are carried out: for example, the SN code is composed of M-bit characters, and the last N bits of the SN are taken as the gazell communication address. For example, N is 5, S/N last five is 34567; assuming that communication is performed by using a signal channels, taking the last N numbers of the SN codes, and dividing the number C by N to obtain an offset parameter, where the frequency band of each signal channel is (C/a × i) + B, and i is 0 to a-1; wherein C is the Gazell bandwidth number, a is the number of signal channels, i refers to the signal channel serial number, and B is the offset parameter.
For example, the following steps are carried out: the last five codes of S/N are 34567, and 5 signal channels are used for communication (in this case, a is 5), then i can be selected to be 0,1,2,3,4, i.e., channel 0, channel 1, channel 2, channel 3, channel 4, channel 5; the above five frequency channels (i.e. channel 0, channel 1, channel 2, channel 3, channel 4, and channel 5) obtained through calculation by the above calculation formula are divided into: 7,23,39,55,71, thereby forming a communication band list [7,23,39,55,71 ].

And the Nordic module at the VR controller end and the Nordic module at the upper computer end establish wireless communication connection for data transmission through a Gazell communication protocol. And the Nordic module at the upper computer end is communicated with the upper computer through a serial port interface, so that an information channel is established between the VR controller and the upper computer.
