bluetooth, nfc, wifi, wwan

Enable, disable, toggle or check the state of builtin bluetooth, NFC, Wi-Fi and WWAN (3G/UMTS, 4G/LTE or 5G) radios:

bluetooth [ on | off | toggle ]
nfc [ on | off | toggle ]
wifi [ on | off | toggle ]
wwan [ on | off | toggle ]

Using the command without arguments displays the actual state.

Hint: for Intel 2200bg and 2915abg cards call the command with sudo or in a root shell.

Prerequisite: the radio device must be supported by the kernel’s rfkill framework (except Intel 2100/2200/2915). This may be checked with rfkill list.
