UART InterfaceThe main communication interface between the RBT-001 and the host is the UARTInterface. The UART interface between host and RBT-001 needs to be connected in NullModem configuration, meaning RTS/CTS and TX/RX are crossed.RBT-001HOSTFigure 1: UART Null Modem connectionThe command interface is based on a command/event based structure. Each command(also called “Request”) will be acknowledged with the appropriate status event (also called“Confirm”). Unexpected events, like incoming link establishment or data, are also sent asevents, but signed with a different package type called “Indicator”. Please see the section"Commands in Command Mode" on page 6 for the detailed description of the commandinterface.Since the RBT-001 acts like a gateway between the Bluetooth Link and the UART interface,the UART connection should use 4-wire hardware handshaking for optimal buffer handling.The RBT-001 uses the RTS lines to indicate low buffers and reacts on the CTS from thehost, immediately stopping sending packages to the host.In case the host microcontroller is not able to provide hardware handshaking, the UARTshould be used in "Command Mode" only, since the device would not be able to indicate fullbuffers by using the RTS signal. In the same way, the host needs to provide enough bufferspace to be able to handle the incoming data, since it’s not able to stop the flow from theRBT-001.RoboTech Bluetooth Serial ModuleUser Manual Ver. 1.211
Command mode and Transparent modeCommand ModeThe RBT-001 offers a wide range of commands to configure the hardware and theBluetooth operation. As the command set is on top of the profiles, Bluetooth operationalcommands are reduced to high level commands controlling general Bluetooth operation.In Command Mode, the RBT-001 will try to interpret all data sent over the UART to aknown command. The commands have to be sent in a specific package format. Theinterface is based on an event mechanism. Any command sent will be confirmed by theappropriate confirmation event. Unexpected events (e.g. incoming links) will be reportedby indication events.Please refer to the following section for a complete list of commands and their usage.Transparent ModeIn case the RBT-001 has established a link to only one remote device and no configurationcommands have to be sent to the RBT-001 ("Command Mode"), the UART interface canbe switched to “Transparent mode”. This means data are directly routed to the Bluetoothlink and not interpreted. Also incoming data are not indicated as events, they are sent asRAW data to the UART.Leaving transparent modeAs the RBT-001 does not listen to commands, UART Break has to be used to tell thedevice to leave the transparent mode.RoboTech Bluetooth Serial ModuleUser Manual Ver. 1.212
