Abstract
A method and system of establishing communications between at least two independent software modules in a safety critical system, such as a medical system, is provided. The design comprises providing an exclusive Bluetooth connection between at least two wireless devices. A master wireless device is configured with Bluetooth master device functionality and a slave wireless device is configured with Bluetooth slave device functionality. The wireless devices are employed in performing a medical procedure. The method further comprises acquiring a stored unique address from the slave wireless device over the Bluetooth connection, comparing the stored unique address to a master wireless device unique address available at the master wireless device, and exclusively pairing the master wireless device and the slave wireless device when the unique address acquired from the slave wireless device is found to identically match the master wireless device unique address.
