SERIAL TO WIFI MODULE [UART, RS232, TTL, WIFI, WIRELESS] IN INDIA

Product Description This is a wifi solution based on IC ESP from Espressif, very price competitive wifi module, and also great function. Bring your project to the internet of things easily! Features: Very competitive price AP, STA, AP+STA modes available. Very simple AT commands, easy to use. internal LWIP interface. Only four pins interface, VCC-3V3, GND, TXD and RXD. Current firmware V091 for all stock, new reserved reset and CH_PD (for updating) pins available, you can refresh the firmware now. All using new ESPex new chip, old chip is not available anymore. Pin description Pin High Status Low Status Note VCC, GND Use standalone power source, or large capacitor, all power of this module from external TXD, RXD The serial port RST - restart CH_PD Flash boot and Update Mode - chip enable, so always connect to high status with VCC GPIO0 - Update mode GPIO2 - - GPIO 15 (when avaialble) NC Flash boot Mode Only for a few version, Wi07-3 GPIO 12 GPIO 13 GPIO 14 GPIO 16 Hardware RST No need any pull-up AT commands §   Baud rate: (from v0.90, v0.80 and older: ) §   The AT part of the command can be written large or small, however, the following command must always be written large §   Make sure that before, after and within the command no spaces (space) occur General AT commands AT command Description Parameter Example AT Test command, are always "OK" back AT AT + RST Reset of the module, the module's boot messages followed by  ready  back AT + RST AT + GMR Querying the Firmware Version AT + GMR WiFi AT commands AT command Description Parameter Example AT + CWMODE =  Setting the WiFi mode  1) Station 1 =  2 = Access Point  3 = Both AT + CWMODE = 1 AT + CWMODE? Query WiFi mode AT + CWMODE? AT + CWMODE =? Query of possible settings for WiFi mode AT + CWMODE =? AT + CIPMUX = Using multiple connections 0 = single compound  1 = Multiple connections AT + CIPMUX = 1 AT + CIPMODE = Setting the data mode 0 = transparent  1 = Data AT + CIPMODE = 1 AT + CIPMODE? Output of the data set mode AT + CIPMODE? WiFi commands (Station / client) AT command Description Parameter Example AT + CWJAP =, Connecting to WiFi network ssid "SSID"  pass "password" AT + CWJAP = "makerday", "M4k3rd4y" AT + CWJAP? Output of the currently connected WiFi network AT + CWJAP? AT + CWLAP Output of available APs  2) AT + CWLAP AT + CWQAP Closes the connection to an access point AT + CWQAP AT + CIFSR Issue its own IP address AT + CIFSR WiFi commands (Access Point) AT command Description Parameter Example AT + CWSAP =, [,,] Set the access point parameters  3) ssid "SSID"  pass "password"  chan "channel"  enc "Encryption"  (0 = Open  1 = WEP  WPA_PSK 2 =  3 = WPA2_PSK  4 = WPA_WPA2_PSK) AT + CWSAP = "makerday", "M4k3rd4y" 5.3 AT + CWSAP? Output the current settings for the AP AT + CWSAP? AT + CWLIF Lists stations connected IPs 4) AT + CWLIF WiFi commands (IP Client) AT command Description Parameter Example AT + CIPSTATUS Output status of the IP connection (s) AT + CIPSTATUS AT + CIPSTART =,, Creating an IP connection with AT + CIPMUX = 0 type: "TCP" or "UDP"  address "IP address"  port: TCP / UDP port AT + CIPSTART = "TCP", " AT + CIPSEND = Sending data over a single compound  5) len: Data length AT + CIPSEND = AT + CIPCLOSE Close a single TCP or UDP connection AT + CIPCLOSE AT + CIPSTART =,,, Creating an IP connection with AT + CIPMUX = 1 id: 0-4  type: "TCP" or "UDP"  address "IP address"  port: TCP / UDP port AT + CIPSTART = "TCP", " AT + CIPSEND =, Send data via merhere compounds 6) id: 0-4  len: Data length AT + CIPSEND = AT + CIPCLOSE = Close one of several TCP or UDP connection id: 0-4 AT + CIPCLOSE = 1 WiFi commands (IP server) AT command Description Parameter Example AT + CIPSERVER = 1 [,] Starts the TCP server port: TCP port AT + CIPSERVER = AT + CIPSERVER = 0 Terminates the TCP server AT + CIPSERVER = 0 AT + CIPSTO = Sets timeout for TCP server timeout = s AT + CIPSTO = 180 AT + CIPSTO? Specifies timeout of TCP server AT + CIPSTO? If a TCP server is started, it can handle up to 5 simultaneous connections. Other compounds can be created, but only served when others are closed or terminated by timeout. The module incoming data directly with the prefix  + IPD  issued: + IPD,   OK   + IPD, 0.6: ON   OK The output is divided as follows: + IPD,,, It is  id  the ID of the compound (0-5),  len  the length of the resulting data packet and  data  contains the data received from the client. In the above example as first sends compound 1 the value   and then connect the string 0  ON     Powered by Turbo Lister
