USCO 01 protokolü ile BlueTooth Uygulaması

[guverdik]

USCO 01 TIVA ARM mikrodenetleyicisi ve HC-06 BlueTooth cihazı ile yapılan örnek bir proje ve kaynak kodları.

BIN ve APK Dosyası     BlueTooth için oldukça güzel bir terminoloji ve bluetooth protokol dökümanları.

Projenin Delphi Kaynak kodları. OrangeUI'dan alıntı bir kalıpla yapıldı.
