第一章--esp8266的使用
ESP8266-wifi模块使用方法
说明：学习esp8266wifi模块与电脑接收与发送数据。
一、原料
硬件：①esp8266-wifi模块
②usb转ttl
③5v转3.3v模块（esp8266仅支持3.3v电压，使用5v模块有几率会被烧坏）
④杜邦线
软件：串口工具sscom32
二、连线
1、wifi模块有8个引脚，要使用它，我们只需要用到5个引脚即可（红框）。
本来不准备画出连线图的，考虑到效率问题，在下面附上（应该多看看esp8266的学习文档，尝试自己连，然后再参考下面的）
2、插电源，插电脑
3、电脑上打开串口工具
插上电后，串口工具显示一堆乱码和一串英文。
这时候我们尝试输入AT并点击发送。
然而此时esp8266模块的默认波特率是115200，所以，不会返回任何数据给串口工具，所以我们需要将模块波特率改为9600才能用。
输入AT+UART=9600,8,1,0,0并点击发送。
然后重启模块。
重启之后，再次发送AT，这时候串口工具会返回OK。
这样就说明模块可以使用了。
模块配置是需要AT指令来执行的，不懂AT指令的话，自行百度哦。
我这里截一下常用的指令，不给你们写注释了（有些我也有点遗忘了，万一写错会误导你们），要学会多百度，不懂再问。

ESP8266 WiFi模块硬件连接指南说明书
Your ESP8266 is an impressive, low cost WiFi module suitable for adding WiFi functionality to an existing microcontroller project via a UART serial connection. The module can even be reprogrammed to act as a standalone WiFi connected device–just add power!The feature list is impressive and includes:802.11 b/g/n protocol Wi-Fi Direct (P2P), soft-APIntegrated TCP/IP protocol stackThis guide is designed to help you get started with your new WiFi module so let’s start!The hardware connections required to connect to the ESP8266 module are fairly straight-forward but there are a couple of important items to note related to power:The ESP8266 requires 3.3V power–do not power it with 5 volts!The ESP8266 needs to communicate via serial at 3.3V and does not have 5V tolerant inputs,so you need level conversion to communicate with a 5V microcontroller like most Arduinos use.However , if you’re adventurous and have no fear you can possibly get away with ignoring the second requirement. But nobody takes any responsibility for what happens if you do. :)Here are the connections available on the ESP8266 WiFi module:ESP8266 WiFi Module Quick Start GuideIntroductionHardware ConnectionsNOTE:Links and Code (Software) Supplied or Referenced in this Document is supplied as a service to our customers and accuracy is not guaranteed nor is it an Endorsement of any particular part, supplier or manufacturer. Use of information and suitability for any application is at users own discretion and user assumes all risk.All rights are retained by the AuthorWhen power is applied to the module you should see the red power light turn on and the blue serial indicator light flicker briefly.If you have a 3.3V FTDI Serial to USB board you can get started without fear of destroying your new ESP8266 WiFi module. Do note that many FTDI boards have a solder jumper to convert from 3.3V to 5V operation so ensure it is set to enable 3.3V operation.Here are the connections required to enable communication with the module over serial:With FTDI 3.3V Board (Legit)DO NOT DO THIS! You may break your Arduino or your ESP8266 WiFi module.This method is a bad idea for a number of reasons:The ESP8266 does not have 5V tolerant inputs–you could destroy your WiFi module.The ESP8266 may draw more current than the 3.3V regulator on your Arduino can supply–you could damage your Arduino.The operation of the ESP8266 outside of stated limits may be unstable and unreliable–you could damage your sanity.This method does have one redeeming feature:If you already have an Arduino Uno R3 it’s really easy to get started and (mostly) worked for me. :)We’re essentially going to use your Arduino as a power supply and USB to serial converter so you need to ensure there is no sketch that interferes with the serial connection. There are a couple of ways to achieve this:Upload an “empty” sketch that doesn’t use the serial connection, e.g. BareMinimum from theWith Arduino Uno R3 (Quick but not very legit)examples menu; or,Remove the microcontroller from the Arduino board (if it is a DIP form factor–don’t undersolder an SMD one).Here are the connections required to enable communication with the module over serial in this configuration:Serial ControlWith the hardware connections in place you can communicate with the WiFi module through a serial terminal.Using Arduino IDE Serial MonitorIf you already have the Arduino IDE installed the easiest way to get started is to use the built-in Serial Monitor:1. Plug in the WiFi module.2. Choose the correct serial port from the Tools > Serial Port menu.3. Open the Serial Monitor via the Tools menu or “magnifying glass” icon on the editor window.4. For the default firmware version (00160901), ensure Carriage return is selected in the lineending pop-up menu at the bottom of the serial monitor. (For later versions it must be set toBoth NL & CR.)5. For the default firmware version, ensure the communication speed is set to 115200 baud. (Forlater versions or if it has been modified it will need to be 9600 baud or similar.)You’re now ready to send your first commands!Using GNU ScreenIt’s possible to use GNU Screen out of the box with the default version of the firmware (00160901) which expects Carriage-Return-only line endings, e.g. (on OS X):screen /dev/bserial-AB12345 115200Unfortunately the updated firmware versions require Carriage-Return-and-New-Line line endings and there appears to be no way to configure screen to send both with one key press. Instead, you need to press <enter> or Ctrl-M then follow that with Ctrl-J.You might have more success with something like minicom or picocom with later firmware versions.Now you’re ready to send your first commands!First Commands1. Ensure AT commands are received correctly (the AT seems not to be case sensitive but therest of any command is case sensitive):ATResponse:OKIf you don’t get this response check:Hardware connections (the blue LED on the board should flash). Try swapping RX & TX.Correct baudrate–should be 115200 on the default firmware version (00160901).Correct line endings–should be Carriage Return only for default firmware version (00160901).If it still doesn’t work, give up, you’ve probably got better things to do with your life…2. Ensure the module is in a known state by issuing a reset command:AT+RSTResponse:ets Jan 8 2013,rst cause:4, boot mode:(3,6)wdt resetload 0x40100000, len 24444, room 16tail 12chksum 0xe0ho 0 tail 12 room 4load 0x3ffe8000, len 3168, room 12tail 4chksum 0x93load 0x3ffe8c60, len 4956, room 4tail 8chksum 0xbdcsum 0xbdreadyOr similar. The important part is the ready on the last line.3. Check the firmware version:AT+GMRThe stock firmware produces this output:001609014. Enable the module to act as both a “Station” and an “Access Point”:AT+CWMODE=3Response:OK(You may need to perform another reset after changing this setting.)5. List surrounding WiFi networks.First, if you’re on (at least) the 00160901 firmware you need to work around an apparent firmware bug that hangs on listing WiFi networks if the last joined network is no longer available.The following command ensures no network details are stored for connection (you should get an OK) response:AT+CWJAP="",""(You can check to see what the currently stored network details are with:AT+CWJAP?which should generate the following output if no network details are stored:+CWJAP:""With a later firmware or if the last joined network is still in the vicinity you shouldn’t need to do this pre-step.)Now you send the actual command to list networks in the vicinity:AT+CWLAPYou should get a response like:+CWLAP:(0,"",0)+CWLAP:(3,"WiFiArtThouRomeo",-80)+CWLAP:(3,"Free Public WiFi",-51)+CWLAP:(3,"Guest",-91)OKSometimes you might get ERROR or no response–in which case you’ll have to try doing the USB plug/unplug cycle and try again. (Or the same with the ground jumper.)6. Join a suitable WiFi access point:AT+CWJAP="<access_point_name>","<password>"You should get an OK response.For example, with the above list of access points you might use:AT+CWJAP="Guest","MyVoiceIsMyPasswordSoWhyDoINeedThis?"You can check if the module has been allocated a IP address with:AT+CIFSRYou should get your current IP address in response, e.g:192.168.1.2Acting as a TCP ClientYou can connect to an internet server (e.g. a web server) with the following method:1. Enable multiple connections (you need an OK response):AT+CIPMUX=12. Specify which connection channel you wish to connect on (0-4), the protocol type (TCP/UDP),the IP address (or domain if you have DNS access) and the port number using the CIPSTART command:AT+CIPSTART=4,"TCP","",80You should receive the response OK followed by Linked when the connection is open:OKLinked3. Next you need to specify how much data you wish to send (after specifying which channel). In thisexample we’re going to send “GET / HTTP/1.0\r\n\r\n” which is 18 bytes:AT+CIPSEND=4,18This time, instead of an “OK” response your will get a > prompt:>This indicates the module is waiting for you to send the 18 bytes of data.Here it gets a bit messy if you’re using the Arduino serial monitor as you have to swap between the line ending the module requires (“Carriage return” only) and what the HTTP server is expecting (“Both NL & CR”). Change the setting to Both NL & CR and send the following (you will need to press Send a second time to send the empty line the HTTP server expects):GET / HTTP/1.0The module should respond with:SEND OKNow you should change the line ending setting to Carriage return only so you can send additional commands.The module should provide a second response once the web server responds:+IPD,4,530:The 4 indicates it’s data from connection channel 4 and the 530 indicates there’s 530 bytes of data. You should now see the data:HTTP/1.0 302 FoundCache-Control: privateContent-Type: ...Woo! You just put a thing on the internet…time to go find a VC!You’ll likely get an OK response or two and then eventually an indication that the server has closed the connection:UnlinkActing as a TCP ServerYou can enable the module to accept TCP connections (i.e. act as a server) in the following manner:1. Connect to a WiFi access point.2. Enable multiple connections.AT+CIPMUX=13. Find out the IP address of the module:AT+CIFSRNote the response, e.g.:192.168.1.24. Set the module to listen (first parameter, mode is set to 1) for a connection on a specific port(in this case port 1336):AT+CIPSERVER=1,13365. From another device on the same network connect to the listening port, e.g. with telnet:telnet 192.168.1.2 1336The module should display:LinkType some text into the telnet session, e.g.:KiwiconAte!The module should display the following (0 being the connection channel, 13 being the length of the data received:+IPD,0,13:KiwiconAte!OKYou can send data in response with the CIPSEND command as used previously, e.g. (0 is the channel, 8 is the length of the data):AT+CIPSEND=0,8The module will display the prompt:>Then you can send the data, e.g.:WhatEvsAnd then the module will respond with:SEND OKThe telnet session should now display:WhatEvsYou can then end the telnet session with by pressing Ctrl-] and q<enter>, the module will display:UnlinkActing as a WiFi Access PointIn addition to connecting to WiFi Access Points the module can also act as an Access Point–this means you can connect devices to the module without any other network infrastructure in place. Ideal for a local private shared “drop box” perhaps…1. The module comes with an access point pre-defined (SSID of “ESP_…”) but you can define yourown with:AT+CWSAP="NoWorriESSID","password",3,0The first parameter is the SSID name; the second parameter is the password; the third the WiFichannel–pick one not used in your area; and, the final parameter is the encryption standard to use.An encryption value of 0 turns encryption off which means the password is ignored–but it still can’t be an empty value. I couldn’t get any encryption to work though (it would always create an unencrypted network) you might have more luck–possibly with a more recent firmware…2. To actually enable the network to be created you need to set the “WiFi mode” of the module to “AP”(2) or “Both” (3):AT+CWMODE=3Now you will be able to connect to your module as an access point from another device (e.g. a laptop or a phone).3. You can list the IP address etc of any device connected to the network with:AT+CWLIFWhich generates the response:192.168.4.100, [...]4. Now you can run the server example from above and connect–note that the module always has theIP 192.168.4.1 when acting as an AP.Updating the firmwareYou’ll be pleased to know you’re not stuck with the ample list of features that ship with your module, no, because you can update the firmware of your module! Yes, that means you can get new features & new bugs too…Finding New Official FirmwareIt’s not particularly easy to find new official firmware versions–the links are spread over forums, wikis and Google Drive accounts which don’t look particularly legit.It seems like the best source of details is the “Updates” section of the “Firmware” section on this page: /w/Wi07c#FirmwareThis ridiculous URL (from the link entitled “Find most upated firmware on this google link” on the above ElectroDragon page) seems to list all the official firmware updates: https:///folderview? id=0B3dUKfqzZnlwR2pVWjg3NXRVdW8&usp=drive_web&tid=0B3dUKfqzZnlwRjFaNTUzZFptbzg#listConsider uploading one of the following versions:ESP8266_flasher_V00170901_00_Cloud Update Ready.zipESP8266_AT_V00180902_02_baudrate watchdog added.zip(A note on version numbers: the version number 00160901 is made up of two parts: 0016 is theSDK version and 0901 is the AT command set version.)Once you’ve updated the firmware you also have the option of “Cloud Updates” but I’ve not managed to get any cloud update to work yet: /cloud-updating-your-wi07c-esp8266-now/Firmware Update ToolsWhile there are other tools for updating the firmware, for this example we’ll use esptoolhttps:///themadinventor/esptool/ which is cross platform and GPL licensed.Download the script file fromhttps:///themadinventor/esptool/master/esptool.py.Hardware Connections and Performing the UpdateIn order to update the firmware you need to configure the hardware to enter firmware update mode:1. Disconnect the module from your computer.2. Connect GPIO0 to ground (0 Volts) (“pulled low”) to enable firmware update mode.3. Reconnect the module to your computer.The module should now be in firmware update mode.(Note that the esptool docs say to ensure “GPIO2 is pulled high” but this doesn’t appear to be necessary.)Execute this command to perform the firmware update (the .bin file is from theESP8266_AT_V00180902_02_baudrate watchdog added.zip archive):python esptool.py --port /dev/bserial-ABC12345 write_flash 0x000000 " v0.9.2.2 AT Firmware.bin"You should receive progress updates during the upload process:Connecting...Erasing flash...Writing at 0x0007ec00... (100 %)Leaving...If you have problems connecting and have been using the Arduino IDE Serial Monitor ensure it isn’t open when trying to perform the upgrade. (Ask me how I know…)Once the update has completed:1. Disconnect the module from your computer.2. Remove the connection from GPIO0 to ground.3. Reconnect the module to your computer.You should now have a new firmware version installed and functioning.Note:The startup behaviour of the module is now different–it displays different output.The module now defaults to communicating at 9600 baud.The module now expects both carriage return and new line characters at the end of every line.New AT commands will be available and some bugs may have been fixed!Arduino and ESP8266Up until now you’ve been manually controlling the WiFI module via the serial console. It’s obviously possible to control the module programmatically via an Arduino sketch. At present there doesn’t seem like a “preferred” choice for an Arduino library to abstract the functionality but a few searches will find you Arduino examples to start with and presumably over time the Arduino community will settle on a preferred library.ESP8266 SDK and Custom FirmwareAn official Software Development Kit (SDK) has been released for the System-on-Chip (SoC) controller which powers the ESP8266 WiFi module. Using the SDK it’s possible to add extra features to the AT command firmware or even create a standalone firmware.Here’s a couple of custom firmwares to check out…NodeMcuLua based firmware for WiFi-SoC ESP8266: https:///nodemcu/nodemcu-firmwareVery cool and easy to get started with.Download the firmware:wget https:///nodemcu/nodemcu-firmware/raw/master/0.9.2/512k-flas h/nodemcu_512k.binFlash the firmware to the module:python esptool.py --port /dev/bserial-ABC123456 write_flash 0x000000 nodemcu_512k.binConnect to the module:screen /dev/bserial-ABC123456 9600Do the obvious…print("hello")For more details look at:https:///nodemcu/nodemcu-firmware#readmehttps:///nodemcu/nodemcu-firmware/wiki/nodemcu_api_enAT Command GPIO controlThere is a custom firmware with AT commands added to read and write the General PurposeInput/Output (GPIO) pins available–this enables you to control LEDs and read buttons with AT commands.For more details see: /esp8266-gpio-test-edited-firmware/More resourcesEspressif Systems (Designer): https:///en/products/esp8266/Espressif Systems Github: https:///espressifESP8266 Community Forum: /NURDspace on ESP8266: https://nurdspace.nl/ESP8266First setup of ESP8266 SDK: https://nurdspace.nl/ESP8266/First_setupElectroDragon on ESP8266: /w/Wi07cFinally…Have fun!Find updates to this guide and more information at /i/follower/p/notes-esp8266.

The blue LED at the upper right corner should be blinking every 2 seconds!6. NodeMCU GPIO for LuaThe GPIO(General Purpose Input/Output) allows us to access to pins of ESP8266 , all the pins of ESP8266 accessed using the command GPIO, all the access is based on the I/O index number on the NoddMCU dev kits, not the internal GPIO pin, for example, the pin ‘D7’ on the NodeMCU dev kit is mapped to the internal GPIO pin 13, if you want to turn ‘High’ or ‘Low’ that particular pin you need to called the pin number ‘7’, not the internal GPIO of the pin. When you are programming with generic ESP8266 this confusion will arise which pin needs to be called during programming, if you are using NodeMCU devkit, it has come prepared for working with Lua interpreter which can easily program by looking the pin names associated on the Lua board. If you are using generic ESP8266 device or any other vendor boards please refer to the table below to know which IO index is associated to the internal GPIO of ESP8266.Nodemcu dev kit ESP8266 Pin Nodemcu devkitESP8266 PinD0 GPIO16 D7 GPIO13D1 GPIO5 D8 GPIO15D2 GPIO4 D9 GPIO3D3 GPIO0 D10 GPIO1D4 GPIO2 D11 GPIO9D5 GPIO14 D12 GPIO10D6 GPIO12D0 or GPIO16 can be used only as a read and write pin, no other options like PWM/I2C are supported by this pin.In our example in chapter 5 on blinking the blue LED, the blue LED in connected to GPIO2, it is defined as Pin4 (D4) in Lua script.7.

ESP8266 ESP-01调试全过程–使用指导测试&编写&汇总by fairyhui一接线注意：本系统是3.3V ! 请勿接5V !新版(全IO口引出版)：此版本若想从FLASH启动进入AT系统，只需CH-PD引脚接VCC或接上拉（不接上拉的情况下，串口可能无数据），其余三个引脚可选择悬空或接VCC(但群里（@云海之梦）反映接VCC后导致无法正常启动)（GPIO0为高电平代表从FLASH启动，GPIO0为低电平代表进入系统升级状态，此时可以经过串口升级内部固件RST（GPIO16）可做外部硬件复位使用）测试系统不同，接线方法也选择多多，请各位根据自己的情况进行选择，推荐接法：在CH-PD和VCC之间焊接电阻后，将UTXD,GND,VCC,URXD连上USB-TTL(两者的TXD和RXD交叉接)即可进行测试旧版(AT指令版)：该版本中间四根线悬空即可。
群里（@ZR(小R)）反应：接线正确的情况下，连上USB转TTL，红灯蓝灯闪烁一下以后全灭，此现象为模块电流过大，超过了USB转TLL模块的承受范围。
解决办法：1. CH-PD换一个阻值更大的上拉电阻；2.换个承受电流大一点USB转TLL模块(群众们也可以自己改造)（@ZR(小R)）反应：在供电不足的情况下，收到的响应为乱码。
请各位检查下供电电压是否足够。
二上电：正常工作验证本模块可以工作在三种模式：1. STA 2 .AP 3 .AP+STA，出厂设置为第三种上电后，蓝色灯微弱闪烁后熄灭，红灯长亮1. 搜索无线网络，可见ESP_XXXXXX已经处于列表中(后面的数字是MAC地址后几位)连接该网络以后，查看连接状态：手机搜索该网络，也可连接上：2.使用USR-TCP232-Test.exe进行测试：软件配置如下图：注意：(1)波特率一般在出厂情况下默认的是115200。
如果在115200情况下收到的是乱码可以试试其他波特率（旧版本的默认波特率可能是其他数值）。
