IoT Platform - Control Box - Message Tx Handler

簡單佈置一下自己的環境

就去工讀生的位置實作 HTTP GET/POST

參考 Wireshark capture

順便將自己電腦 node.js 的 hello.js 在 8888 port 開起來

看來可以偷玩一下 newifi mini

IoT Platform - Control Center - newwifi mini - OpenWrt JXcore Package Creation

參考 2015-12-26 0825 - OpenWrt JXcore - Package Creation

目前已經成功參考 OpenWrt JXcore Package Creation
build 出 package jxcore_0.3.0.3_ramips_24kec.ipk

該文件再來談到

You should find the packages below and download them on your computer.

libpthread...
librt..
libstdcpp..

Once you have all the ipk files, copy all of them to your device. In order to install a ipk package;

opkg install <ipk file>

You are expected to install all three packages before installing jxcore package.

準備一下材料

上傳這四個 ipk 到 newifi mini 上然後安裝

root@OpenWrt:/tmp# opkg install libpthread_0.9.33.2-1_ramips_24kec.ipk
Installing libpthread (0.9.33.2-1) to root...
Configuring libpthread.
root@OpenWrt:/tmp# opkg install librt_0.9.33.2-1_ramips_24kec.ipk
Installing librt (0.9.33.2-1) to root...
Configuring librt.
root@OpenWrt:/tmp# opkg install libstdcpp_4.8-linaro-1_ramips_24kec.ipk
Installing libstdcpp (4.8-linaro-1) to root...
Configuring libstdcpp.
root@OpenWrt:/tmp# opkg install jxcore_0.3.0.3_ramips_24kec.ipk
Installing jxcore (0.3.0.3) to root...
Configuring jxcore.

裝好了... then?

放一隻 hello.js 在 /tmp 下

root@OpenWrt:/tmp# cat hello.js
var http = require("http");

http.createServer(function(request, response) {
  response.writeHead(200, {"Content-Type": "text/plain"});
  response.write("Hello World");

  console.log("someone request");

  response.end();
}).listen(8888);
console.log("Node.js running...")

跑吧... jx

root@OpenWrt:/tmp# jx hello.js
Node.js running...

眼淚快掉下來了
