Hi,
The polling rate of all devices such as a mouse, keyboard and a dualshock 4 controller, connected via TP-Link UB400 Bluetooth dongle is only 125 Hz.
Is there an inherent limitation that forces lower polling rate that I'm not aware of?
The dongle allows higher polling rate on windows, all devices support higher polling rate as well. Internal raspberry pi 4 Bluetooth controller is able to establish at least 250hz by default as requested by all of the devices. Dualshock 4 connected via USB also works at 250hz by default. It's only whenever the dongle's bt controller is used is when I'm forced down to 125hz. Tried setting mousepoll/jspoll settings, as well as min/max interval in Bluetooth LE config.
Any ideas? Using the latest Raspberry pi os on Pi4
Thanks
