To reduce powerconsumption of the system, the RBT-001 supports a specific Wake up functionality.The RBT-001 supports to disable the UART transport layer (command "Disable TransportLayer") to switch off the command interpreter and all hardware components not needed forthe current operation. The interface can be reactivated again by either side by usinghardware pins. The RBT-001 uses the RTS signal pin to wake up the host. The RTS / CTSsignals are connected in a NULL-Modem fashion (i.e. "crossed"), meaning that RTS on theHost is connected to CTS on the RBT-001 and vice versa. Therefore the host would needto be able to monitor its CTS input or has to use a separate hardware pin. In case theRBT-001 has to be triggered by the host, the RTS pin is used as the hardware Wake-Upsignal.Disable Transport LayerDescriptionPacketType REQOpcode DISABLE_TLDataLength 0This Command disables the transport layer and thereby allowingpower saving.RoboTech Bluetooth Serial ModuleUser Manual Ver. 1.238
