A device having circuits (3) for communication according to the Bluetooth specification deviates from the strict specification by not having a unique Bluetooth device address BD ADDR. Instead, it has an address switching circuit (1) that chooses the device address from a group of BD ADDR addresses and stores it in a rewritable register (5). The address switching circuit switches the BD ADDR stored in the register from time to time, for example triggered by specific events. The device can communicate without any conflict with similar devices and with devices built strictly according to the Bluetooth specification. The switching of device address preserves privacy of the device.
