Problems solved by technology

There are two main methods for code matching. One method is manual code matching. This method requires manual participation after the transceiver is produced. Manually (such as wireless mouse / keyboard pressing a combination button or software method) writes the random code value In non-volatile memory (such as EEPROM), and one of the pair of devices after manual coding is damaged, the other one needs to be coded again before it can continue to be used, which will cost extra costs and is not flexible enough to use

Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0021] A wireless transceiver mainly has a sending end and a receiving end.

[0022] Such as figure 1 Shown: a kind of automatic coding method of wireless transceiver, comprises the following steps:

[0023] 1) After the sending end and the receiving end start working, each initializes the configuration of the wireless module; the sending end sends the first command and enters a state of waiting for a response; if the receiving end receives the first command within a certain period of time (milliseconds), it will send a response. And generate the second random number of N2 bytes, otherwise it will continue to receive the judgment; if the sender receives the response signal within a certain period of time (milliseconds), it will generate the first random number of N1 bytes, otherwise it will restart Send the first command. The N1 bytes of the first random num...

Abstract

The invention provides an automatic code matching method for wireless transceivers. Mainly, a transmitting end and a receiving end are adopted to carry out handshake response mutually so as to ensure mutual connectivity; the transmitting end and the sending end respectively generate random numbers; the respectively generated random numbers are merged according to rules appointed by both parties to generate a unique random code so as to ensure uniqueness of the random code. According to the automatic code matching method, any one pair of wireless transceivers can correspond to each other and do not interfere with each other. In the method, repeated handshake response of the transmitting end and the receiving end reduces an error rate generated by code matching. The transmitting end and the receiving end respectively have the own random numbers, correspond to each other, are not interfered by other wireless devices and also do not interfere other wireless devices.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a code matching method for a wireless transceiver. Background technique [0002] The wireless transceiver mainly has a sending end and a receiving end (such as a wireless mouse / keyboard remote and dongle), the sending end is mainly for sending data, and the receiving end is mainly for receiving data. In order to prevent more than one pair of wireless transceivers from interfering with each other and affecting product performance, a code pairing technology was developed. There are two main methods for code matching. One method is manual code matching. This method requires manual participation after the transceiver is produced. Manually (such as wireless mouse / keyboard pressing a combination button or software method) writes the random code value In the non-volatile memory (such as EEPROM), and one of the pair of devices after manual coding is damaged, the other one needs to be...
