六,ESP8266 TCP Client(基于Lua脚本语言)

今天不知道是不是让我姐挺失望.......很多时候都不知道自己努力的方向对不对,,以后能不能带给家人最美好的期盼......

Init.lua 没啥改变,,就改了一下加载Client.lua

gpio.mode(4,gpio.OUTPUT)

gpio.mode(2,gpio.OUTPUT)

gpio.write(4,1)

tmr.alarm(0,1000,1, function()

gpio.write(4,1-gpio.read(4))

end)

tmr.alarm(1,3000,0, function()

dofile("Client.lua")

end)

新建了一个Client.lua

wifi.setmode(wifi.STATIONAP)

cfg={}

cfg.ssid="Hellow8266"cfg.pwd="11223344"wifi.ap.config(cfg)

apcfg={}

apcfg.ssid="qqqqq"apcfg.pwd="11223344"wifi.sta.config(apcfg)

wifi.sta.autoconnect(1)

ClientConnectedFlage=0TcpConnect=nil

tmr.alarm(1,1000,1, function()ifClientConnectedFlage ==0then

Client= net.createConnection(net.TCP,0)

Client:connect(8080,"192.168.1.103")

Client:on("receive", function(Client, data)

uart.write(0,data)

end)

Client:on("connection", function(sck, c)

ClientConnectedFlage=1TcpConnect=Client

print("Link OK")

tmr.stop(1)

Client:on("disconnection", function(sck, c)

ClientConnectedFlage=0TcpConnect=nil

tmr.start(1)

end)

end)ifClientConnectedFlage ==0then

print("Link Error")

end

end

end)

uart.on("data",0,function(data)ifTcpConnect ~=nil then

TcpConnect:send(data)

end

end,0)

printip=0wifi.eventmon.register(wifi.eventmon.STA_DISCONNECTED, function(T)

printip=0end)

wifi.eventmon.register(wifi.eventmon.STA_GOT_IP, function(T)ifprintip ==0then

print("+IP"..T.IP)

end

printip=1end)

现在测试

现在创建服务器

发送数据测试

现在断开连接

第一次没有截到网络调试助手的图,模块就连接上了,,所以又断开了一次

现在就用这个读取AD的电压值

命令和回复呢咱就这样规定

现在的init.lua

gpio.mode(4,gpio.OUTPUT)

gpio.mode(2,gpio.OUTPUT)

gpio.write(4,1)ifadc.force_init_mode(adc.INIT_ADC) then

node.restart()returnend

tmr.alarm(0,1000,1, function()

gpio.write(4,1-gpio.read(4))

end)

tmr.alarm(1,3000,0, function()

dofile("Client.lua")

end)

现在的Client.lua

wifi.setmode(wifi.STATIONAP)

cfg={}

cfg.ssid="Hellow8266"cfg.pwd="11223344"wifi.ap.config(cfg)

apcfg={}

apcfg.ssid="qqqqq"apcfg.pwd="11223344"wifi.sta.config(apcfg)

wifi.sta.autoconnect(1)

ClientConnectedFlage=0TcpConnect=nil

tmr.alarm(1,1000,1, function()ifClientConnectedFlage ==0then

Client= net.createConnection(net.TCP,0)

Client:connect(8080,"192.168.1.103")

Client:on("receive", function(Client, data)

uart.write(0,data)

ReadAd(data)

end)

Client:on("connection", function(sck, c)

ClientConnectedFlage=1TcpConnect=Client

print("Link OK")

tmr.stop(1)

Client:on("disconnection", function(sck, c)

ClientConnectedFlage=0TcpConnect=nil

tmr.start(1)

end)

end)ifClientConnectedFlage ==0then

print("Link Error")

end

end

end)

function ReadAd(data)ifdata =="++MD9"then

ad= adc.read(0)ifTcpConnect ~=nil then

TcpConnect:send("++MDAD="..ad)

end

end

end

uart.on("data",0,function(data)ifTcpConnect ~=nil then

TcpConnect:send(data)

end

end,0)

printip=0wifi.eventmon.register(wifi.eventmon.STA_DISCONNECTED, function(T)

printip=0end)

wifi.eventmon.register(wifi.eventmon.STA_GOT_IP, function(T)ifprintip ==0then

print("+IP"..T.IP)

end

printip=1end)

现在测试

对了测试的电压是0-1V    然后分辨率是  1024

我现在接到3.3上

如果数据向加CRC校验,看这篇文章的最后

五,ESP8266 TCP服务器多连接

TCP 就说道这里
