合宙LuatOS AIR700 IPV6 TCP 客户端向NodeRed发送数据

为了验证 AIR700 IPV6 ，特别新建向NodeRed Tcp发送的工程。

Air700发送TCP数据源码如下：

--[[
IPv6客户端演示, 仅EC618系列支持, 例如Air780E/Air600E/Air780UG/Air700E
]]-- LuaTools需要PROJECT和VERSION这两个信息
PROJECT = "IPV6_SendDate_Nodered_TCP"
VERSION = "1.0.0"log.info("main", PROJECT, VERSION)-- 一定要添加sys.lua !!!!
sys = require("sys")
libnet = require "libnet"
local netc-- 演示task
sys.taskInit(function()-- 仅EC618系列支持, 例如Air780E/Air600E/Air780UG/Air700Eif rtos.bsp() ~= "EC618" thenwhile 1 dolog.info("ipv6", "only Air780E/Air600E/Air780UG/Air700E supported")sys.wait(1000)endend-- 启用IPv6, 默认关闭状态,必须在驻网前开启-- 注意, 启用IPv6, 联网速度会慢2~3秒mobile.ipv6(true)log.info("ipv6", "等待联网")sys.waitUntil("IP_READY")log.info("ipv6", "联网完成")sys.wait(100)socket.setDNS(nil, 1, "119.29.29.29")socket.setDNS(nil, 2, "114.114.114.114")
end)sys.taskInit(function()sys.waitUntil("IP_READY")local dName = "D2_TASK"netc = socket.create(nil, dName)local succ=socket.config(netc)log.info("socket.congfig",succ )local succ1, result = socket.connect(netc, "www.yourUrl.top",12300,true)log.info("socket.connect",succ1) log.info("IPV6", "ip", socket.localIP())sys.wait(2000)local cnt=0local strCntwhile true docnt=cnt+1strCnt="From Air700 No."..cnt.." Messages."local succ1, full, result1 = socket.tx(netc, strCnt)-- local succ1, full, result1 = socket.tx(netc, strCnt, "www.yourUrl.top",       12300       )  --TCP应用则忽略      --端口--TCP应用则忽略log.info("socket.SEND",strCnt) sys.wait(6000)endend)-- 用户代码已结束---------------------------------------------
-- 结尾总是这一句
sys.run()
-- sys.run()之后后面不要加任何语句!!!!!

代码中注意点：

1       socket.connect(netc, "www.yourUrl.top",12300,true)

  socket.connect函数的need_ipv6_dns必须设置成true，以便开启IPV6.

2  socket.tx(netc, strCnt, "www.yourUrl.top",12300 )  函数中的域名和端口号可以忽略。
                                                         

3 行号52 sys.wait(2000)延时不能少，可保证NodeRed收到第一条数据

]

NodeRed接收数据

 Air700发送的数据

注意：NodeRed是基于Docker运行的

 外部TCP端口号是12300，Docker内部是2300

注意上述问题，即可验证AIR700是支持IPV6的。
