IoT我都想搞一年前買了一板nrf51822開發板BLE4，可惜愈恆心搞下去，本來用它來控制LED bulb, 一係用藍牙4 ...

介紹剛剛出BLE4 IC nrf52832， 近期都去華強買了LED bulb 9W 人仔9元幾平,現在用緊幾好。

what is "BLE4 IC nrf52832"?
come with library?
i don't want any accessory with no library to come with.
i don't know if i can make my own library to make it work. even though, i can. it will cost me so much time.

using bluetooth to do remote control?

Nordic Semiconductor nrf52832 has its SDK.

i am too stupid. i don't want to dive into something else apart from arduino.
so, i just include the library of bluetooth functions? and call it?

Yes, nrf52 DK (nrf52832 development card)has GPIOs which are controlled by mobile phone's app.

    wt server do u mean. you mean using raspberry pi? ever considered nodejs for raspberry pi?

   e 你好似明我講咩喎!我想用pi做家中server比指令Arduino,所以arduino又係server,因為比服務。
Arduino mcu吾夠勁去處理AES加密，又無可能做到multithread，所以用pi做server比指令，而係係同一個wifi網路下，本身個wifi網路有加密，所以係wifi網路下吾加密都無問題。
但我要寫個程式比pi,又會加密又可以multithread同一時間聽幾個connection,e部分未試。

我用pebble time,佢有mic,支援c或JavaScript, 好似係node.js.
但網路個部分係一定要用JavaScript 寫入json file(我無估錯的話，因為我睇過佢d tutorial做),之後send出。所以我諗應該跟住d sample code改改應該可以send到出去，不過pi server要分析個json, 我用c++玩過下個library讀寫json叫jsoncpp,但當然用python方便好多，我舞睇錯記錯，python內置有library讀寫json,之前學puthon見到，個時吾知json係咩，而且又吾會用到。
我望過用Python加socket加multithread d code，應該吾難，加密都望過下。
我覺得最難個部份係實踐放係一齊。
