Paul bearne / HC05

Bluetooth module HC-05 Lib. suppotrs printf(); support IrqAttach, with using RTOS. include feature as background rxIrq attach. the lib store rx buf of serial, therefore can have over 16 bytes string. if you want to get string, you call read() or getLine(). read() is ALL string, getLine() is under CR('\r').

Dependencies:   RingBuffer
