Are you using the last version of AutoDisconnect?
If you disable the Bluetooth check, AutoDisconnect doesn't do anything! Try Code: ps | grep auto in command mode to be sure no bluetooth checker is running!
ps | grep auto
$ ps|grep auto 7806 root 2088 S /bin/ash /opt/autodisconnect/autodisconnect-network-c 8345 user 2088 S grep auto
