- outputs = Default low level, support serial instruction control and input KEY pin control in network state
- status = In non mesh mode, low level if not connected, high level after connection In mesh mode (output high level if connect to network successfully, if not, output low level)
- inputs = inputs
- PWRC descriptions = Support PWRC pin wake-up in deep sleep state, and AT instruction sending is supported when the connection status is pulled down
- LED_status = In non mesh mode (flash if not connected, light on after connection)
