Web UI over bluetooth very slow

This was last discussed 3 years ago … While from memory things did improve thanks to work from @falkTX and maybe others, unfortunately I still find this to be painfully slow. Given that the main use case is for minor “emergency” tweaking at gigs, the speed is kind of problematic.

As mentioned in Save preset edits when not attached to GUI?, I’ve hunted high and low for a dongle faster than Bluetooth 4.0 but not had any luck finding one yet. Does anyone else have suggestions for improving the speed of the web UI over Bluetooth?

Or perhaps there is another way, such as using a wifi dongle which would allow communication via an access point or via Wi-Fi Direct mode?
