- Low voltage alarm: LED indcates voltage of Lipo
- CTS/RTS lines are needed? just connect in loop back if no flow control is needed.
- CTS is needed for waking up from deep sleep?
- Serial API callback when data are available/received(and when send buffer is available)
- Serial API instance several serial ports can be used
