Brain Boxes products will run at the maximum Bluetooth data rate of 1 MBaud. Please see Bluetooth Baud Rates in the Bluetooth data sheet. The effective data throughput is 721kbps once encryption and authentication is taken into account. To achieve these speeds, the RS232 Adaptor (BL-510) must be attached to a fast serial port (e.g. Brain Boxes CC-302 PCI 2 Port Velocity RS232 ).
