r/logitech on Reddit: Any workarounds to connect a BLE Logitech keyboard with a laptop that has Bluetooth 3.0?
June 8, 2024 -

I am trying to connect either to my Logitech MX Keys mini or MK850 keyboards to an "old" Toshiba Satellite L735 laptop (that uses Qualcomm Atheros Comm AR3011 Bluetooth 3.0) via Bluetooth and also with the Logitech Unifying Receiver and cannot get them working.

First I tried to connect via Bluetooth, but I am seeing that this might not be possible due to Bluetooth 3.0 and BLE (both keyboards use this). For this I guess I'd need to upgrade the Bluetooth hardware, right?

Second I tried connecting the MK850 keyboard using the unifying receiver using debian's (bookworm) package solaar (1.1.8+dfsg-2), everything seems to be working fine, but when I connect the USB receiver and I start typing with the keyboard the laptop (seems to crash and) shuts down immediately. If I reboot it and I have the receiver connected it keeps shutting down, so I can only run my laptop if I disconnect that USB receiver.

I saw my logs using journalctl -b -1 looking for any errors but didn't quite find anything, I will replicate this and give it another look in case I missed to spot anything useful.

In the meantime, do you have any workarounds for connecting these devices? Have you faced any similar issues as mine? Would love to hear about it and thanks in advance :)
