lm [mode]

With no mode , prints link mode. MASTER or SLAVE mean, respectively, to ask to become master or to remain slave 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 MASTER and ACCEPT . NONE sets link policy to the default behaviour of remaining slave and not accepting baseband connections when there are no listening AF_BLUETOOTH sockets.

If ACCEPT is present, the device will accept baseband connections even when there are no listening AF_BLUETOOTH sockets.
