六,ESP8266 TCP Client

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(,gpio.OUTPUT)
gpio.write(,)

tmr.alarm(, , , function()
    gpio.write(,-gpio.read())
end)

tmr.alarm(, , , function()
    dofile("Client.lua")
end)

新建了一个Client.lua

wifi.setmode(wifi.STATIONAP)

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

apcfg={}
apcfg.ssid="qqqqq"
apcfg.pwd=""
wifi.sta.config(apcfg)
wifi.sta.autoconnect()

ClientConnectedFlage =
TcpConnect = nil
tmr.alarm(, , , function()

    if  ClientConnectedFlage ==  then
        Client = net.createConnection(net.TCP, )
        Client:connect(,"192.168.1.103")

        Client:on("receive", function(Client, data)
            uart.write(,data)
        end)

        Client:on("connection", function(sck, c)
            ClientConnectedFlage =
            TcpConnect = Client
            print("Link OK")
            tmr.stop()

            Client:on("disconnection", function(sck, c)
                ClientConnectedFlage =
                TcpConnect = nil
                tmr.start()
            end)
        end)

        if  ClientConnectedFlage ==  then
            print("Link Error")
        end
    end
end)

uart.on("data",,function(data)
    if  TcpConnect ~= nil then
        TcpConnect:send(data)
    end
end, )

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

wifi.eventmon.register(wifi.eventmon.STA_GOT_IP, function(T)
   if printip ==  then
      print("+IP"..T.IP)
   end
   printip =
end)

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

如果用的ESP12系列的可以现在就用这个读取AD的电压值

命令和回复呢咱就这样规定

现在的init.lua

gpio.mode(,gpio.OUTPUT)
gpio.write(,)

if  adc.force_init_mode(adc.INIT_ADC) then
    node.restart()
    return
end

tmr.alarm(, , , function()
    gpio.write(,-gpio.read())
end)

tmr.alarm(, , , function()
    dofile("Client.lua")
end)

现在的Client.lua

wifi.setmode(wifi.STATIONAP)

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

apcfg={}
apcfg.ssid="qqqqq"
apcfg.pwd=""
wifi.sta.config(apcfg)
wifi.sta.autoconnect()

ClientConnectedFlage =
TcpConnect = nil
tmr.alarm(, , , function()

    if  ClientConnectedFlage ==  then
        Client = net.createConnection(net.TCP, )
        Client:connect(,"192.168.1.103")

        Client:on("receive", function(Client, data)
            uart.write(,data)
            ReadAd(data)
        end)

        Client:on("connection", function(sck, c)
            ClientConnectedFlage =
            TcpConnect = Client
            print("Link OK")
            tmr.stop()

            Client:on("disconnection", function(sck, c)
                ClientConnectedFlage =
                TcpConnect = nil
                tmr.start()
            end)
        end)

        if  ClientConnectedFlage ==  then
            print("Link Error")
        end
    end
end)

function ReadAd(data)
    if  data == "++MD9" then
        ad = adc.read()
        if  TcpConnect ~= nil then
            TcpConnect:send("++MDAD="..ad)
        end
    end
end

uart.on("data",,function(data)
    if  TcpConnect ~= nil then
        TcpConnect:send(data)
    end
end, )

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

wifi.eventmon.register(wifi.eventmon.STA_GOT_IP, function(T)
   if printip ==  then
      print("+IP"..T.IP)
   end
   printip =
end)

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
