3.10.2 interactive interface application
L710HG provides three shook hands with application processor communication signals. Application
processor can query whether the module boot normal work through STATUS. Through the
WAKEUP_OUT query module is in sleep mode, and sleep in the module, through WAKEUP_IN
wake module. Similarly, when application processor in the sleep state, the L710HG modules can
through WAKEUP_OUT wake application processor
.
 STATUS：Module sleep instructions, high level indicator to sleep, low level instructions for the
awakened state;
 WAKEUP_IN： The host can lower the signal awakens the module，If, low level has maintained,
module can't sleep.
 WAKEUP_OUT: when L710HG need to communicate with the AP, module can be set this pin for
low level to awaken application processor.
 FLGHTMODE：Through the external input low level module into flight mode;
FLIGHTMODE pin can be used to control module to enter or exit the flight mode. In flight mode, L710HG
internal radio frequency circuit is closed. FLIGHTMODE reference circuit as shown in the figure below:
