The function module is externally displayed with a function aggregate, such as a function that the module supports network registration, a function of sending User Datagram Protocol (UDP) data, a function of sending Transmission Control Protocol (TCP) data, a function of shutdown and the like.
The following detailed description is given with reference to specific examples.
The embodiment of the invention provides an AT instruction system based on object orientation. Referring to fig. 1, the system includes:

A sending unit 102, configured to call an AT instruction in an object-oriented AT instruction set and send the AT instruction to the function module 11;
the receiving unit 103 is configured to receive an execution result returned by the functional module 11.
The object-oriented AT command will be described below by taking UDP data transmission as an example.
+SendUDPDataFunc
The AT command is used for sending a packet of UDP data
+SendUDPDataFunc＝<ipaddr>,<port>,<data><CR><LF>
+SendUDPDataFuncERROR＝<ErrorCode><CR><LF>
<CR><LF>ok<CR><LF>
Or
+SendUDPDataFuncSuc<CR><LF>
<CR><LF>ok<CR><LF>
Or
<CR><LF>ERROR<CR><LF>
Description of the parameters
< ipaddr > character string
IP address, automatically identified by the bottom layer as being IPv4 or IPv6
< port > integer
Port number
< data > character string
Content of transmission
+SendUDPDataFuncERROR
Failed transmission
< Errorcode > integer
Error code
+SendUDPDataFuncSuc
Success of transmission
For example: AT + SendadPDataFunc 99.99.99.99,7000 just ATestData
+ SendUDPDataFuncSuc// indicates successful transmission
OK
+ SendadPDataFuncERROR: 666// represents transmission failure, 666 represents UDP connection establishment failure
OK
Other AT command principles are similar and are not described in detail here.
The functional module 11 further includes:
the instruction acquisition and analysis unit 111 is used for receiving and analyzing an object-oriented AT instruction sent by the MCU 10;

a return unit 114 for returning the execution result of the processing unit 113 to the MCU 10.
The return unit 114 returns the execution result to the MCU10 as whether the function was successfully executed.
Preferably, the MCU further comprises: and the display unit is used for displaying the execution result of the AT instruction.
The object-oriented AT command system provided in this embodiment implements an operation on an AT command by using the function module as an object, using configuration data of the function module as data of the object, and using a function provided by the function module as an action of the object, and has the advantages of simple process logic, convenient use, low requirement on an MCU, and reduced use threshold of a client.
Referring to fig. 2, a second embodiment of the present invention provides an AT instruction processing method based on object-oriented. The method comprises the following steps:
step S201, the MCU sends an object-oriented AT instruction to the functional module;

The following illustrates an object-oriented AT command transmission procedure by transmitting UDP data.
Please refer to fig. 3, which is a flowchart illustrating a process of sending UDP data according to a third embodiment of the present invention. The process of sending the UDP data comprises the following steps:
step S301, the MCU sends an AT instruction for sending UDP data to the functional module;
step S302, judging whether the basic functions of the functional module are normal, and if so, performing step S303;
and the functional module returns the judgment result of whether the function module is normal to the MCU.
Step S303, performing a network registration function;
the function module performs a network registration function.
Step S304, judging whether the registration is successful, and if so, performing step S305;
and the functional module returns the result of whether the registration is successful to the MCU.
Step S305, performing a UDP data transmission function;
the function module performs a UDP data transmission function.
Step S306, judging whether the transmission is successful, and if the transmission is successful, performing step S307;
and step S307, ending the process.
And the functional module returns the result of whether the transmission is successful to the MCU. If it fails, a failure code is returned.
