With no mode, prints link mode. CENTRAL or PERIPHERAL mean, respectively, to ask to become central or to remain peripheral when a connection request comes in. The additional keyword ACCEPT means that baseband connections will be accepted even if there are no listening AF_BLUETOOTH sockets. mode is NONE or a comma−separated list of keywords, where possible keywords are CENTRAL and ACCEPT. NONE sets link policy to the default behaviour of remaining peripheral and not accepting baseband connections when there are no listening AF_BLUETOOTH sockets. If CENTRAL is present, the device will ask to become central if a connection request comes in. If ACCEPT is present, the device will accept baseband connections even when there are no listening AF_BLUETOOTH sockets.
