alt Hacker NewsBluetooth mice use the HID protocol borrowed from USB, except with Bluetooth as carrier. But HID had not been designed for the possibility that packets could get lost: it sends movements as a relative vector since the previous packet.
I don't know how Logi Bolt works, but Logitech has claimed that it should work better than BLE when the 2.4 GHz band is congested. Also that it would have better security than BLE.

Bolt can't be better than BLE because it is BLE. Same with Apple gear which pairs so seemlessly.
It's just that they control both sides of the signal so can better optimize the connection.
I mean, you can't type in BitLocker password wirelessly without a dongle. Optical mice sensors aren't so repeatable anyway, so missing a packet or two probably aren't so critical.

Doesn't the same problem exist for USB dongles with proprietary RF protocols?
Logi Bolt is a good solution. But ime most other USB dongles are terrible. I have had a lot of bad connection issues with such USB dongles, and never with similar bluetooth devices. USB dongles also use the same 2.4GHz band, and even more they are prone to interference from nearby active USB ports [0]. If you have ever had a "jumping" mouse while transfering big amounts of data through a port neighbouring your mouse's USB dongle, this is likely the reason.
