RBT-001 Module - User Manual v.1.2

Force Master on/offThis flag improves multipoint operation of the RBT-001. In normal operation, the RBT-001will be slave for any incoming link, which limits the number of incoming connects to 2devices.In case the Force Master Bit in the NVS is set to On, the RBT-001 will request a roleswitch on any incoming link to become Master.Force Master On: Request Role Switch on incoming link to become Bluetooth Master. Link will bedropped if role switch not successful. Force Master Off: Accept incoming link as slaveDefault connections stored in NVSIn case the automatic operation bit is set to On, the default connections database ischecked for any valid entry. If a valid entry is found, the RBT-001 tries three times toconnect to each device stored in the database.Default connection transparent On/OffEach default connection can be configured to switch the UART to "Transparent Mode" orto "Command Mode" after link establishment. In case the transparent flag is set, theRBT-001 will switch to "Transparent Mode" once the link is established.NOTE: The transparent flag can only be activated if only one default connection is storedin the databaseOperation StatesAs combination out of the different parameters and usage scenarios, the following statescan be defined for the RBT-001. The parameters and possibilities for this states aresummarized in the following Table "Overview of Operation States".An example on how to read the Table: E.g. Scatternet Master (assuming default NVSsettings). In Scatternet Master, the device is in command mode (listening to commands). The automatic flag in NVS has no influence. The device is discoverable andconnectable for other devices. The device is Master for x slaves and slave to 1 Master. It is possible to search for other devices but it is not possible to be connected fromanother device. RAW data traffic is not possible. No Incoming link possible. In case the command interface is used to establish a link to another device, thedevice stays in "Scatternet Master". A UART BREAK has no influence on the functionality. Sending the command"Transparent Mode" is not applicable for this mode.RoboTech Bluetooth Serial ModuleUser Manual Ver. 1.216
