I have recently purchased a Lenovo Thinkpad E480 laptop, I have installed Ubuntu 18.04 on it, everything is working fine except its not able to switch on the Bluetooth. Please help.
I followed this link, but am unable to solve the issue.
Below are the outputs of some commands.
lspci -nnk | grep -iA3 net

It seems I have to clone, compile and install the required Bluetooth driver, please guide me which Bluetooth driver to use and how to install (with steps if possible).
P.S.: Let me know if any further information is needed to solve this issue, I will add the required info (if any) in the question as per the guidance given.
You can see the even though the bluetooth switch is toggle on, it still shows the bluetooth is 'off'.
