1. 設(shè)置模塊連接路由器，并打印路由器分配的ip：
Init.lua文件：
tmr.alarm(0,4000,0,function()
dofile("tcpclient.lua")
end)
Init.lua文件結(jié)束
tcpclient.lua文件：
wifi.setmode(wifi.STATION)
cfg={}
cfg.ssid="qqqqq"
cfg.pwd="11223344"
wifi.sta.config(cfg)
printip = 0
wifi.eventmon.register(wifi.eventmon.STA_DISCONNECTED, function(T)
printip = 0
end)
wifi.eventmon.register(wifi.eventmon.STA_GOT_IP, function(T)
if printip == 0 then
print("+IP-> "..T.IP)
end
printip = 1
end)
tcpclient.lua文件結(jié)束

2. 參照官方手冊，創(chuàng)建客戶端連接服務(wù)器；看見模塊獲取了ip但是連接不上服務(wù)器
Init.lua文件：
tmr.alarm(0,4000,0,function()
dofile("tcpclient.lua")
end)
Init.lua文件結(jié)束
tcpclient.lua文件：
wifi.setmode(wifi.STATION)
local stacfg={
ssid="qqqqq",
pwd="11223344"
}
wifi.sta.config(stacfg)
wifi.sta.autoconnect(1)
TCPClient = net.createConnection(net.TCP,0)
TCPClient:connect(8080,"192.168.0.105")
TCPClient:on("receive", function(sck, data)
uart.write(0,data)
end)
TCPClient:on("disconnection", function(sck, c)
print("Disconnection")
end)
TCPClient:on("connection", function(sck, c)
print("Connection")
end)
----------Got IP Style:+IP-> xxx.xxx.xxx.xxx----------------------------
printip = 0
wifi.eventmon.register(wifi.eventmon.STA_DISCONNECTED, function(T)
printip = 0
end)
wifi.eventmon.register(wifi.eventmon.STA_GOT_IP, function(T)
if printip == 0 then
print("+IP-> "..T.IP)
end
printip = 1
end)

3. 是不是，沒有獲取到ip就去連接了呢？添加一個(gè)定時(shí)器延時(shí)10秒后再去創(chuàng)建TCP客戶端連接服務(wù)器，這下可以看到能連接上服務(wù)器

那斷開服務(wù)器，再重新打開服務(wù)器，客戶端又不連接了。。。

4. 如何讓模塊斷開連接后一直自動(dòng)重連服務(wù)器呢？

6. 我想使用串口助手給模塊發(fā)送數(shù)據(jù)，然后讓模塊吧數(shù)據(jù)發(fā)送給TCP服務(wù)器：
TCP服務(wù)器發(fā)送的數(shù)據(jù)我們通過模塊的串口發(fā)送出來了，但是服務(wù)器并沒有接收到串口發(fā)送過來的數(shù)據(jù)
