TP link is making a false and misleading claim on Amazon that is supports BLE for Window-11, but in fact it does not support it.  I had communicated with their tech-support and three different support personnel are responding with boiler-plate respones. It is abvious none of these TP-Link support people know about LE audio or BLE.  They keep pointing me to the the compatibility device list and that does not even even a single BLE device in the list.  How does tp-link claim that it support BLE and has it tested that with any one device in the market for LE audio?

I think Tp-link is blindly getting what Realtex is advertising and have no clue of BLE or  its working on Windows-11.  I suggested them to follow the Microsoft suggestion to verity that it works and give me the specifics of one LE Audio device/headset that it is tested with - no response to the actual question. 

Check if your Windows 11 PC supports Bluetooth Low Energy Audio - Microsoft Support

This is Tp-link false claim on Amazon.
