Query on the speed of input of Bluetooth

I stopped being able to take the noise of the keyboard when connect with cables so I switched to using BT between the halves and BT to the host.

What it feels like is that the rate of input is much slower and the characters are slower to appear on the screen? Does anyone else experience this?

Or is this a more subtle form of the lagging and freezing?

In my experience, almost every board I’ve tried with bluetooth is slow to respond.

Do you have a UHK80 dongle? It’s much better than BLE.

(Just btw., the dongle also works via BLE. Not sure why exactly the ble hid yields so different results.)
