<Solved>Available Devices are not shown when Bluetooth is on

[omkar2205]

Hi,

I had recently installed lmde 5 on my new PC. Initially bluetooth and wireless icon are not shown.

However after upgrading to latest kernal via backport, bluetooth icon is available.

When i switched on bluetooth, even though they are available devices they are not being shown.

following are some of the details
