OS: Ubuntu 20.04
Kernel: 5.4.0-31-generic

Summary:
Bluetooth file transfer via Bluetooth UI on the Ubuntu System is too slow

Description:
When using the UI to connect and transfer the file form one machine to another 
machine, BASIC mode is getting selected in the L2CAP configuration and 
continuous scan is not going on in both sides. the L2CAP MTU size is also in 
672, which is very small. Even with the patch applied by Intel, it does not 
increase the TPT because the UI always selects BASIC mode.

Steps:
1. On the top right corner of the system's screen (system 1) click on the 
System Tray
2. Click on Bluetooth Settings, and turn Bluetooth ON
3. Using another system (system 2) with Ubuntu installed, turn on Bluetooth and 
pair with the system 1.
4. Confirm the Bluetooth PIN
5. Send Files via Bluetooth from system 1 to system 2
6. Send Files via Bluetooth from system 2 to system 1

Expected Result:
File transfer via bluetooth have a fast transfer for small size files. 

Actual Result:
File transfer via bluetooth to another fedora system too slow. 


Sample File transfer duration:
sending - (8MB) 5min 18s
sending - (12MB) 7min36s
receiving - (8MB) 4min 8s
receiving - (12MB) 5min 48s
