In a change from previous PlayStation controllers, the Sixaxis features wireless connectivity based on the Bluetooth standard. However, the Sixaxis lacks a Bluetooth "discovery mode", which is normally used for connecting to Bluetooth devices wirelessly, so a wired USB connection is required to set up the Sixaxis with the appropriate Bluetooth address before a wireless connection can be made. When used with the PSP Go, a PS3 is required to set up the Sixaxis.
