Unfortunately they only tested Logitechs unifying system, that's known to be broken (mentioned in the paper). That's one of the reasons Logitech is moving to Logi Bolt, which is supposed to be very similar to BLE (but with a separate receiver). I'd be really interested to know if it's also as secure as BLE.

Do you know why, then, they went with their own, yet-another-new protocol, instead of just using BLE? One hint may be that on my Macbook my Logitech mouse appears to have a higher latency (feeling more "spongy") when connected via Bluetooth instead of via the dongle.

  Their keyboards also support BLE with the actual host. Using their dongle has the advantage of working as well as a wired device on a system that isn't yet booted as you are paired to the dongle not the host, and the dongle then acts as standard USB devices. Putting a more complete Bluetooth host into their dongle would just change the edges of where it is incompatible with normal Bluetooth usage.

  The hardware is great, but I can't bring myself to buy anything that requires running Logitech's software. I've heard elsewhere Logitech devices are laggy on bluetooth. Why isn't this an issue for Apple and other manf? I've moved from mech keyboards with O-ringed MX blues to pretty much using the Apple magic keyboard and trackpad anytime I'm at the desk. Sometimes I still reach for the clicky-claky, but integrated Touch-ID is so useful I've taken a liking to using the Apple magic keyboard (with touch id) and grown accustomed to the feel.

You can configure them, and they'll remember the settings on their on-board memory. They're also supported by Piper on Linux, so you never have to touch the crappy Logitech software. I also have one of their trackballs, and it's a pain having to make sure the software runs so that the sensitivity is the correct one. It does Unifying and BT, and I've actually been impressed with how well the latter works. I don't feel any difference between that and the Unifying dongle, be it on a current-gen Linux PC or on an old MBP.

      This isn't applicable to the G-Series, but the MX Master and M720 (plus some other niche models) support smooth scrolling, which can only be enabled on Windows and macOS using their 300-or-something Electron app that nags you to sign in to their stupid cloud service. Of course the basic features (pointer/scrolling speed) can still be configured within the OS.

      I can compare with the built-in keyboard/trackpad for my laptop or with wired hardware. Which I assume all have zero latency. So I think I'd notice if there was significant latency on any of my bluetooth devices...
