After the calibration data for receiving terminal device transmission each time, according to priority from up to from stored each baud rate
Low one baud rate not being selected of sequential selection is as current baud rate, later according to current baud rate to receiving
Calibration data carries out parsing and obtains parsing calibration data, if the parsing calibration data and preset standard calibration number that obtain
According to identical, then current baud rate is configured to the work baud rate of WiFi module, and send successful match instruction to make terminal device
Dwelling period sends calibration data, the calibration data that otherwise receiving terminal apparatus is sent again.Terminal device is according to its baud
Rate sends calibration data, only when current baud rate is identical as the baud rate of terminal device, according to current baud rate to calibration
The parsing calibration data that data carry out parsing acquisition just can be identical as standard calibration data, thus successively will be stored each
Baud rate is compared after parsing as current baud rate to calibration data with standard calibration data, can determine terminal
The baud rate of equipment, and then configure the baud rate of WiFi module to identical as terminal device, it is adaptive to realize WiFi module
The baud rate of terminal device, without the baud rate in developer's manual modification code, so as to reduce WiFi module baud
The degree of manual intervention in rate configuration process.
Optionally, on the basis of WiFi module baud rate collocation method shown in Fig. 1, if judging to solve in step 104
It is identical as preset standard Calibration Data to analyse calibration data, illustrates that current baud rate is identical as the baud rate of terminal device,
At this point, in stored each baud rate highest priority can be set by the priority of current baud rate.
After determining that a baud rate is identical as the baud rate of terminal device, highest is set by the priority of the baud rate
Priority, when re-powering after WiFi module power-off, WiFi module can preferentially select the baud rate to send terminal device
Calibration data is parsed, if the terminal device connecting with WiFi module is not replaced, only needs to carry out one to calibration data
Secondary parsing can determine the baud rate of terminal device, can configure corresponding baud for the work baud rate of WiFi module
Rate, so as to reduce configuration WiFi module baud rate, selection has stored time that baud rate parses calibration data in the process
Number, and then promote the efficiency of WiFi module adaptive configuration baud rate.
Optionally, at least two general standard baud rates are stored in advance as the object selected, general standard wave
Special rate can be 4800,9600,19200,38400 or 57600.For example, 4800,9600,19200,38400 and are stored in advance
57600 total 5 general standard baud rates are as the object selected.
General standard baud rate is the shared baud rate of most terminal devices, for example in intelligent appliance field, terminal is set
Standby air-conditioning common baud rate when carrying out serial communication is 19200, and terminal device refrigerator is common when carrying out serial communication
Baud rate is 9600.By multiple general standard baud rates, alternately baud rate is stored in WiFi module, guarantees WiFi mould
Block by stored standard baud rate can with the baud rate successful match of most of terminal devices, i.e., for most of ends
End equipment, WiFi module can be configured the work baud rate of itself to by way of adaptive baud rate and corresponding terminal
Equipment is identical, and the success rate of itself baud rate is configured so as to promote WiFi module by adaptive baud rate mode.
Optionally, for stored each baud rate, each wave can be set according to the numerical value of each baud rate
The priority of the smaller baud rate of the priority of special rate, specially numerical value is higher.
For example, stored baud rate includes 4800,9600,19200,38400 and 57600 total 5 baud rates, according to
The sequence of priority from high to low, the ranking results of 5 baud rates are followed successively by 4800,9600,19200,38400,57600,
That is after receiving the calibration data that terminal device is sent for the first time after WiFi module powers on, first by 4800 as current
Baud rate parses calibration data, if parsing obtains parsing, calibration data is different from standard calibration data, by 9600
The calibration data received again is parsed as current baud rate, and so on until by 57600 be used as current bauds
Rate.If by 57600 as current baud rate to receive calibration data carry out parsing acquisition parsing calibration data still with mark
Quasi- calibration data is different, then the adaptive baud rate failure of WiFi module, needs developer by way of manually pair
The baud rate of WiFi module is configured.
Optionally, the priority of baud rate has been stored other than it can be configured according to the numerical values recited of baud rate, also
The number that can be arranged to WiFi module work baud rate according to baud rate is configured.Specifically, it determines and solves in step 104
After analysis calibration data is identical as standard calibration data, for each stored baud rate, the baud rate history is obtained
The accumulative number for being configured as WiFi module work baud rate, the number that will acquire are defined as the successful match time of the baud rate
Number carries out more the priority of stored each baud rate later according to the corresponding successful match number of each baud rate
Newly, so that the priority of the more baud rate of Corresponding matching number of success is higher.
For example, 9600 numbers for being arranged to WiFi module work baud rate are greater than for stored 5 baud rates
19200 be arranged to WiFi module work baud rate number, 19200 be arranged to WiFi module work baud rate number it is big
It is arranged to the number of WiFi module work baud rate in the number that 38400 are arranged to WiFi module work baud rate, 38400
It is arranged to the number of WiFi module operating bit rates greater than 4800,4800 are arranged to the number of WiFi module operating bit rates
It is arranged to the number of WiFi module work baud rate, after the priority to 5 baud rates is updated, 5 greater than 57600
Baud rate is followed successively by 9600,19200,38400,4800,57600 according to the sequence of priority from high to low.
It should be noted that when acquisition baud rate history adds up to be configured as WiFi module work baud rate, and non-acquisition
Some WiFi module works the facilities of baud rate in history, but obtains a large amount of WiFi modules and work in history baud rate
Facilities, for example obtain the feelings that stored each baud rate is arranged to work baud rate in 100,000 WiFi modules
Condition.Specifically, set work baud rate can be uploaded to unification after work baud rate is arranged by each WiFi module
Server, each WiFi module, which can obtain each from above-mentioned server and store baud rate, later is arranged to operating wave
The number of special rate.
It is further to note that previous embodiment will be arranged to the preferential of the baud rate of WiFi module work baud rate
Grade is set as highest priority, which can be updated it to the priority of each baud rate completing the present embodiment
After carry out.
The number that baud rate is arranged to WiFi module work baud rate is more, illustrates serially to be led to using the baud rate
The quantity of the terminal device of letter is more, makes to be arranged to the more wave of WiFi module work baud rate number by updating priority
The priority of special rate is higher, make WiFi module can preferentially select the more baud rates of counterpart terminal number of devices and terminal device into
Row matching, it is possible to reduce the number that WiFi module selection baud rate parses calibration data, i.e. reduction WiFi module and end
End equipment carries out the matched number of baud rate, so as to improve the efficiency of WiFi module configuration baud rate.
Optionally, it on the basis of above-mentioned each embodiment provided WiFi module baud rate collocation method, can also connect
Externally input baud rate more new command is received, and stored baud rate is carried out according to the baud rate received more new command
New baud rate is deleted or stored, realizes the update to baud rate has been stored.
Relative to stored each baud rate, when the terminal device for being carried out serial communication using new baud rate is occurred
Or after quantity increases to certain numerical value, new baud rate can be stored into WiFi module, so that WiFi module can pass through
Adaptive baud rate be normally carried out serial communication using the terminal device of new baud rate, promote the applicability of WiFi module.
For stored each baud rate, if the frequency of use of wherein one or more baud rates is very low, such as
Frequency of use is lower than 5%, then can delete these baud rates from stored each baud rate, to promote WiFi module certainly
Adapt to the rate of baud rate.
