(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
