How to turn On and Off bluetooth visibility mode?
Solution 1:
In BlueZ >= 5 command line control of a device can be done with btmgmt tool:
sudo btmgmt
[mgmt]# help # list commands
[mgmt]# info # list device(s)
[mgmt]# select hciX # select a known device by index X eg. hci0
[hci0]# discov yes # make hci0 visible/discoverable
[hic0]# discov no # make hci0 invisible
In older version of BlueZ we can control our Bluetooth device with the command line tool hciconfig.
To enable visibility:
sudo hciconfig hciX piscan
To disable visibility:
sudo hciconfig hciX noscan
Replace hciX
with your device (usually hci0
)
To query your Bluetooth device(s):
sudo hciconfig -a
