Androidble4.0藍芽開發相容2.0藍芽應用(針對arduino藍芽控制小車開發應用HC-08，06藍芽模組的連線)

1.嗯有段時間沒更新部落格啦，給廣大CSDN友上點幹活
2.android藍芽即智慧穿戴裝置火起來之後藍芽的普及也是有點猛，今天我們部落格的主題就是圍繞arduino開發藍芽控制小車寫的測試demo，連線的藍芽模組是HC-08,06型號，所以出廠的硬體UUID是廠商提供的，增對該demo用的範圍也是有限的，當前藍芽的開發功能和庫的使用基本都是一樣的，不一樣的只是硬體藍芽模組的UUID，假如想做智慧手環什麼的換成手環的藍芽UUID就可以用，嗯，就是這麼簡單
3.下面先上個gif圖爽爽看看效果先，本人基本都是先看效果再決定是否下載該demo
由於我的網路不是很好用的遠端投屏至電腦才錄製的gif所以看起來搜尋藍芽有點卡，實際效果是不卡的，中間出現的警告框是樓主的手機後臺記憶體只有600+M所以有一個實時監測手機記憶體的，防止記憶體不足demo崩了，嗯，個人感覺還是不錯的
4.下面上主要程式碼截圖：MainActivity

CSDN上傳下載分不能為0了所以我選擇了最少的2分，資源分不多的可以去我github下載，喜歡的可以點個star哦，謝謝了！
6.還有一個樓主寫了一個專門用於arduino控制藍芽小車的APP喜歡的和需要的可以去應用寶下載下來爽爽哦，個人感覺比SPP功能強太多哦，歡迎下載,搜尋HFEasyControl！
6.插播幾張APP的截圖給大家爽爽
