Chapter 4 – Examples Multi-Point Example using MTS2BTSMI or MTS2BTA One Master and Four Slave Devices Note: Attaching the fourth slave device can overload the connections and cause all connections to be terminated. Increasing the distance between Bluetooth devices will effect performance and could further limit the number of connections. Setup hardware for this example consisting of up to five MTS2BTSMI or MTS2BTA Bluetooth units connected through serial ports to workstations. One unit is configured as master and four units are configured as slaves. The master needs to be firmware version 3.6.2.1.0.0 or newer to support multipoint connections. The slaves are not firmware dependent and can be older models. All Bluetooth units are configured with baud rate of 9600bps, 8 data bits, no parity, 1 stop bit and hardware flow control. Baud rate can be set up to 115.2kbps but all Bluetooth devices need to be set to same baud rate. Each workstation uses a terminal emulator like HyperTerminal or ZOC to communicate to Bluetooth device using AT commands. Configure the slave Bluetooth devices to function as slaves in data mode. - Verify local device is Slave in Data Mode.
