embedded Wi-Fi module. The AT+ command protocol uses a set of command based on ascii to communicate with the Wi-Fi chip through the UART interface. 1.2 Control Command Protocol 1.2.1 Command Code This section is a user command for implementing parameter configuration and networking transmission of the product. The command list is as follows: Number Luat Instruction Name Function 1 (null) Null Operation Instruction 2 ATM Set/query operating mode 3 ATRM Set/query socket connection information automatically created in automatic operating mode 4 BSSID Set/query the BSSID address of the specified AP 5 BRDSSID Enable and disable the SSID broadcast of the AP 6 CHL Set/query the specified wireless channel mode 7 CHLL Set/Query Wireless Channel List 8 CNTPARAM Query the configured networking parameters 9 CUSTDATA Receive user data sent via one-click configuration tool 10 DNAME 11 DNS Set/query device name Set domain name of network card 6 /73 Air602_AT Instruction User Manual 12 13 ENCRY Switch serial port character echo Set/Query Wireless Network Security Mode 14 ENTM Enter serial port transparent transmission mode 15 ENTS Set the system to enter energy saving mode 16 HTTPC 17 KEY Set/Query Wireless Network Key 18 LKSTT Query network connection status 19 LKSTT2 Query network connection status 2, valid only in APSTA mode 20 NIP 21 Luat E ONESHOT HTTP post get data function Set/query the local IP address Turn one-click configuration on or off 22 PASS Set / query system password 23 PMTF Update all parameters in memory to Flash 24 PORTM 25 QMAC Query physical address 26 QMAC2 Query physical address 2, valid only in APSTA mode 27 QVER Query version information 28 RSTF Reset Factory settings 29 SKCLS 30 SKCT 31 SKGHBN 32 SKRCV Set the interface mode of the wireless network card Close socket connection Create a socket connection Get the IP of the server Receive data via a Socket connection 7 /73 Air602_AT Instruction User Manual Luat 33 SKRPTM Open or close the socket to actively report the receiving data function 34 SKSDF Set the default send socket connection 35 SKSND Send data over a socket connection 36 SKSRCIP Query socket data source IP address 37 SKSTT 38 SLIST Query the STAs that have been connected, valid only in AP and APSTA modes. 39 SSID Set/Query Wireless Network Name 40 SSID2 Set/query the wireless network name, valid only in APSTA mode 41 UART Set / query serial data format 42 WATC Set/Query to automatically create an Adhoc network 43 WEBS Set/Query Web Server 44 WJOIN Join/create a wireless network 45 WLEAV Disconnect wireless network 46 WPRT Set/Query Wireless Network Type 47 WPSM Turn energy saving mode on/off 48 WSCAN Scan Network 49 WWPS Set / Query WPS Features 50 Z Query socket connection status Reset 8 /73 Air602_AT Instruction User Manual 1.2.2 Erro Code The error codes supported by this system are defined as follows： ASCII Luat Description - Success -1 Invalid command format -2 Command not supported -3 Invalid operator -4 Invalid parameter -5 Operation not allowed -6 Not enough memory -7 FLASH error -8 System busy -10 access the network failed -11 No socket available -12 Invalid socket -13 Socket connection failed -62 Socket failed to send -63 Socket reception failed -64 Undefined error 9 /73 Air602_AT Instruction User Manual 2 AT Command Protocol 2.1 Syntax Description This module uses the AT+ command protocol as the user control protocol. The AT+ instruction protocol uses a set of command line format instruction sets based on ascii. The syntax format and processing flow are described below. 2.2.1 Syntax format • Format Description <>： Indicates the part that must be included [ ] ： Indicates the optional part • Command Message AT+[op][para1],[para2],[para3],[para4]… AT+ ： Command message prefix CMD：Command String [op]： Instruction operator, when the command needs to take a parameter, you can specify the operation type of the parameter, including： =， Parameter/Return value preamble =!， In the setting parameter class command, it means that the modification is synchronized to flash, and the restart does not disappear. ；If there is no ! after = , it means that it is only saved in memory, and the parameters disappear after restarting. =?，In the Set Parameter Class command, query the current settings. ：Carriage Return，ascii character 0x0d • Response message + [op][para1],[para2],[para3],[para4]… +： Response message prefix RSP： Response string OK Success ERR Failure Luat 10 /73 page Air602_AT Instruction User Manual ：Carriage Return，ascii character 0x0d ：Line feed，ascii character 0x0a Data Type • String：String， Surrounded by double quotes, the content does not contain quotes, e.g.："this is a string" Dec： Decimal number ， e.g.：10 Hex： Hexadecimal number ， e.g.：a Ip：ip address string ， e.g.：192.168.0.1 MAC： Consists of 12 hexadecimal digits ， e.g.: 001EE3A80102 2.1.1.1 Processing flow The AT+ instruction protocol takes the form of command + response. Most instructions require the receiver to return a response message after processing. If a new command is received again during the previous command processing, it will be silently discarded without returning. Any message, as shown below: User System AT+Commad1 Processing command 1 response1 AT+Commad2 AT+Commad3 Processing command 2 Discard command3 response2 Luat 11 /73 page Air602_AT Instruction User Manual For some special commands, such as AT+SKSND, AT+SKRCV, it is necessary to transmit binary data after the instruction or response details. At this time, the receiver of the command transmission temporarily enters the transparent transmission state and starts receiving the binary data stream until receiving the specified length of data in the field of the message or command, or until the waiting timeout, automatically exits the transparent transmission state, the flow is as follows: User AT+SKRCV Enter transparent reception status and automatically exit after receiving User Sys +OK= Return response message Sys AT+SKRCV=, Return response message +OK= Enter transparent reception status and automatically exit after receiving 2.1.1.2 Example Format exampl1： Return success message AT+ +OK Example 2: Return error message AT+WJOIN +ERR=-10 Example 3: Set input parameters AT+UART=9600,1,1,0 +OK Example 4: Synchronizing parameters to the Flash operator Luat 12 /73 page Air602_AT Instruction User Manual AT+ATPT=!500 +OK Example 5: Using the Query Operator AT+ATPT=? +OK=500 2.2 Instruction Definition 2.2.1 System Control Class Instruction 2.2.1.1 Null Operation Instruction：AT+ • Function: empty operation, can be used to detect whether the program is responding normally • Format（ASCII）： AT+ +OK • Parameter：Null • e.g.：（ → indicates input, ← indicates return or ac ve report, the same below ） → AT+ ← +OK 2.2.1.2 System Reset：AT+Z • Function： System Reset . • Format（ASCII）： Luat 13 /73 page Air602_AT Instruction User Manual AT+Z +OK • Parameter：Null • e.g.： → AT+Z ← +OK ready 2.2.1.3 Set Echo：AT+E • Function： Switch serial port command echo • Format（ASCII）： AT+E +OK • Parameter：Null • e.g.： → AT+E ← +OK 2.2.1.4 Serial port enters transparent transmission mode ：AT+ENTM • Function： Serial port enters transparent transmission mode ;the system exits this mode when it receives an escape character that matches the trigger condition in transparent transmission mode. Attention： Before entering the transparent transmission mode, the following conditions must be met: 1. Connected to the Internet 2. Create a socket 3. Set the transparent connection to the currently created socket Luat 14 /73 page Air602_AT Instruction User Manual • Format（ASCII）： AT+ENTM +OK • Parameter：Null • e.g.： Entering the transparent mode requires the following steps: 1. Connect to the internet → AT+E ← +OK → AT+KEY=1,0,"" ← +OK → AT+WJOIN ← +OK=3c46d82bd81e,0,11,0,"TP-LINK_ Luat_AP ",51 2. Creat a socket → AT+SKCT=0,0, 36.7.87.76,1000,2000 ← +OK=1 3.
