Visibility of Logi MX devices over Bluetooth

Hello!

I am facing some weird behavior of Logi MX peripherals. I am currently using 3 devices with my Lenovo Legion 7:
- MX Keys (office)
- MX Anywhere 3 (office)
- MX Anywhere 2s (home)

Everything works just fine, until I boot Windows on the same machine and connect MX Anywhere 2s to windows. After that Linux stops seeing advertising of all 3 devices an nothing helps.
There are several threads on forums suggesting clearing of scan patterns. But it does not help. Removal of `/var/lib/bluetooth` also does not help.
Last time it started to work again after `hidpai` library upgrade. But yesterday I've broke it up again after connecting the mouse under windows.

The controller:
```
> lspci
05:00.0 Network controller: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter

```

With `bluetoothctl` I can't even see devices advertising, while I see them from phones and other laptops.

Any help is very appreciated...

This is not relevant. For some reason all Logi devices become invisible for the system. Even those who was never connected to windows.
Re-connection of a device would not be an issue, I am not logging windows much often.

I need to find any solution how to make devices visible on Linux again.

`bluez-utils-compat`  and `hcitool lescan` didn't help as well

```
> hcitool lescan
Set scan parameters failed: Operation not permitted

> sudo hcitool lescan
Set scan parameters failed: Input/output error
```

Re: Visibility of Logi MX devices over Bluetooth

did u check systemctl if bluetooth.service is running?

Of course, I can see other Bluetooth devices during scan: phones, TVs etc

what kind of bluetooth-manager do u use?

The one from gnome, but I also tried Blueman and Solaar. They provide the same result.

do u use logitech dongle?

No, no dongles.

did u unblock rfkill?

How can I check and unblock rfkill?

Re: Visibility of Logi MX devices over Bluetooth

just type rfkill for checking status  and rfkill unblock -devicename- .
If it is still blocked try connmanctl enable bluetooth. details in 6.9 about connman

> rfkill 
ID TYPE      DEVICE                SOFT     HARD
 0 wlan      ideapad_wlan      povoleno povoleno
 1 bluetooth ideapad_bluetooth povoleno povoleno
 2 bluetooth hci0              povoleno povoleno
 3 wlan      phy0              povoleno povoleno

Does not look like an issue. I tried to block 1 and 2 and then it was automatically unblocked by gnome bluetooth manager toggle
