The wifi/bluetooth modules AX201, AX210 and AX211 (cases 0x18, 0x17 and 
0x19 respectively) used in various notebook devices started having 
issues as of the patch that enabled le coded phy in the driver. (We also 
use AX200, however without issue.)

Noted behaviour as of the issues: Device scan took longer and when it 
did find a device connection often failed or timed out.

I do not know if a special type of bluetooth client is affected. It was 
partially tested by looking at the difference in enumeration of the 
current mix of bluetooth clients in the area (where you could clearly 
see the difference at a glance) and with one specific device.  A 
bluetooth connected watercooling system (TUXEDO Aquaris or 
LCT21001/LCT22002) where a test case showed the mentioned issues.

Best regards,

Christoffer
