The inquiry command is used to discover all Bluetooth radios (within range) that match a certain Class of Device
(COD). If the COD is not known it is best to use 00000000 which allows discovery of all devices. You can not be
in the default slave mode and perform an inquiry command. Only a Master or a Radio in idle mode can perform an
inquiry.
