Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the present invention provides a WiFi module configuration method based on UDP broadcast length coding, including the following steps:
In the embodiment of the present invention, the preamble packet, the configuration packet, and the data packet all use length coding, and information in each packet is placed in a length part of a UDP packet, where a length of length information stored in one UDP packet is 10 bits, and a specific data format is shown in fig. 2:
the 10 th bit of the leading packet is 1, and the other 9 bits are 0.
The 10 th bit of the configuration packet and the data packet is 0; the 5 th to 9 th bits form index information, and the index information comprises 5 bits in total; bits 3 and 4 are 1/4 bytes of valid Data; the 1 st and 2 nd bits are No. information; the value range of No. information is 0-3. More specifically, the index information value in the configuration packet is 0, the No. information value of the configuration packet is 0 and 1, and Data constitutes 4-bit Data for representing the length of the WiFi password; the index information value of the configuration packet is 0, the No. information value is 2 and 3, and Data form 4bit Data to indicate the length of the SSID; the value range of the 4-bit data is 0-15, and the lengths of the WiFi password and the SSID are not 0, so that the length ranges of the WiFi password and the SSID are 1-15. The value of No. information in the Data packet is 0, 1, 2 and 3, the value of index information is the same, Data can form an 8-bit byte for representing one ASCII coded character in the WiFi password and SSID content information, therefore, the value range of the index of the Data packet is determined by the sum of the WiFi password and the SSID length value in the configuration packet, and the maximum value range is 2-30. And arranging the Data in the Data packet according to the order of the index information from small to large, splicing the Data with the length of the former WiFi password to form WiFi password content information, and splicing the Data with the length of the next SSID to form SSID content information.
The process is illustrated with a simple example:
as shown in fig. 3, the mobile phone, the wireless router and the WiFi module have three terminals in common, and the mobile phone terminal sends 20 consecutive preamble packets to the wireless router. And the WiFi module receives any continuous 4 preamble packets in the process of scanning the wireless router channel, namely locking the channel and waiting for receiving the configuration packet. The mobile phone end continuously sends 2 groups of configuration packets to the wireless router, and one group comprises 4 UDP packets. And after receiving the information of the WiFi password length and the SSID length in the configuration packet, the WiFi module waits for receiving a data packet containing the WiFi password and the SSID content. And the mobile phone terminal sequentially sends data packets containing WiFi passwords and SSID contents to the WiFi module and waits for 9s, the WiFi module executes the action of connecting the wireless router after receiving and analyzing, and after the data packets are successfully connected, the mobile phone terminal continuously sends status packets successfully configured for 10 times to the local area network. And if the mobile phone end receives the status packet of successful configuration sent by the WiFi module in the waiting window period of 9s, the configuration process is ended, and if not, the steps are repeated.
Compared with distribution network methods such as SmartConfig and the like, the method has the advantages that CRC (cyclic redundancy check) is removed, the packet length and the packet number of a preamble packet, a configuration packet and a Data packet are compressed in a compact packet coding format to reduce Data transmission quantity, Data error rate caused by CRC removal is reduced through double verification of No. information and index, the complexity of interaction between a mobile phone and a WiFi module is reduced through strict control of a Data transmission flow, and distribution network speed and success rate are improved.
The above embodiments are only used for illustrating the design idea and features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present invention and implement the present invention accordingly, and the protection scope of the present invention is not limited to the above embodiments. Therefore, all equivalent changes and modifications made in accordance with the principles and concepts disclosed herein are intended to be included within the scope of the present invention.
