Hi...Can anybody tell me where i can find Bluetooth log file
/var/log/syslog - there you will find bluetooth entries.
The Bluetooth DCE device also puts its log entries in /var/log/pluto/xx_Bluetooth_Dongle.sh.log
replace xx with the Device ID # that DCE assigned the Bluetooth Device. This can also be viewed in the web admin, by clicking on Follow Log, in its device page under Advanced > Configuration > Devices
