Microduino-WIFI(ESP)

Language	English

Microduino-ESP Microduino-WiFi (ESP) module is a WiFi communication module, through the serial port Transmission data to Core / Core + / CoreUSB core module for communication, you can connect other WiFi devices. Features Serial Communications； It can be connected to the Internet； Small, cheap, stack, open source； Specifications Forms of communication: Serial passthrough, the default port for the D2 (RX), D3 (TX); Power supply：+3.3VDC 50mA； Status indicator; Common AT commands All AT commands are end with "\ r \ n". When the AT command debug please pay attention to select "\ r \ n". Common AT commands： AT+RST Restart module AT+GMR Check the version information AT+CWMODE=3 station and access point 1 Station Mode 2 AP Mode 3 AP and Station AT+CWLAP wifi ssid List AT+CWSMARTSTART=0 enable smart configer 0: use 安信可 AI-LINK technology 1: use ESP-TOUCH technology 2: use AIR-KISS AT+CWSMARTSTOP stop smart configer AT+CWJAP="<access_point_name>","<password>" join a WiFi AT+CIFSR show wifi infomation AT+CIPSTATUS Get the connection status AT+CIPSTART=4,"TCP","baidu.com",80 Establishes a TCP or UDP connection, port.

We have set SSID (wifi name) and pass (password) places in the code, change your wifi password Download program Stack together with Microduino-WiFi(ESP), Microduino-Core+ and Microduino-USBttl, insert USB line into the Microduino-USBttl, other side of USB line insert into computer, start Arduino IDE, The above program is copied to the IDE, the tool (tools) -> Board (Board) is selected Microduino Core, and the tools (tools) -> Serial Port (Serial) select the corresponding serial number. After clicking the top left corner IDE √ button to compile the program, after the end of the compilation click -> button is programmed to the board; Open the serial monitor, set：“\r\n”、“115200 baud”. First of prompts is to show connect WiFi successful information If you see the following description you already visited Baidu Home website. Serial Pin Description 文件:Microduino-WiFi(ESP)-1Big2.jpg Microduino-WiFi(ESP) Application Related Applications： WiFi Weather Stations Firmware programming instructions 1：welds point marked "down", or use wire to connect GND and GPIO0(written on the back of the board of the vias 0) 2：Recommend use USBTTL transfer serial directly, you need connect four wires to transfer serail port. WIFI(ESP) USBTTL D2 D1（TX1） D3 D0（RX0） 3V3 3V3 GND GND If you use the core module programming firmware, please do the serial converter with Core+ module, can not use Core, because WIFI (ESP) serial port is (D2, D3) pin 115200 baud rate, the corresponding Core is soft serial port, baud rate less than 115200. The USBTTL, Core+ stack, download the program to the Core+ module. #define my_Serial Serial1 //Core+ or CoreUSB void setup() { Serial.begin(115200); my_Serial.begin(115200); } void loop() { if (Serial.available()) { char c = Serial.read(); my_Serial.write(c); } if (my_Serial.available()) { char c = my_Serial.read(); Serial.write(c); } } soft serial port to hard seral port:文件:SoftToHard-V2.rar 3：Connect USB, open burn firmware tool, set firmware address update firmware. Firmware tool software：文件:ESP8266Flasher.rar Firmware file：文件:MicroduinoESP8266.rar Connect USB to PC, your firmware tool software will show below: 文件:Microuino-WiFi(ESP)burnLoarderStep1.png 600px setup as below: v0.9.5.2 AT Firmware-------------0x00000 Find right firmware file in floder and fill right address 文件:Microuino-WiFi(ESP)burnLoarderStep2V1.png 600px return operation tab, and click burn 文件:Microuino-WiFi(ESP)burnLoarderStep2-1.png 600px 文件:Microuino-WiFi(ESP)burnLoarderStep3.jpg 600px 4：Open debugging tools, test AT command make sure whether the firmware burn successful 5：Finally remove the weld on "down" or disconnect the wire which connect GND and GPIO0(written on the Questions Gallery 文件:Microduino-WiFi(ESP)-t1.png 600px 文件:Microduino-WiFi(ESP)-b1.png 600px 文件:Microduino-WiFi(ESP)-t.png Microduino-WiFi(ESP) Front 文件:Microduino-WiFi(ESP)-b.png Microduino-WiFi(ESP) Back
