              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 MASTER is present, the device
              will ask to become master 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.
