I have disabled Bluetooth in the Intel Nuc Bios, but in Windows 10 it is still on, when I scan Bluetooth devices with my phone, it is still found it seems that windows 10 overides the Intel Nuc Bios is this a bug ? Is there a Bios updat for this?

  1. Since the Bluetooth radio, uses the same Wireless Adapter with WiFi, probably you need to disable also the PCIe Port in M.2 Wireless Slot (For WLAN) as well.
  2. Other possibility to make hide your NUC and to make it invisible for Bluetooth devices is setting in Windows. Switch Bluetooth to OFF.

Thank you,

 

You say:

you need to disable also the PCIe Port in M.2 Wireless Slot (For WLAN) 

 

But I have an ssd installed in the M.2 Slot if disabled then the ssd wil no longer work or is this another slot?

 

In windos 10 I have already disabled the the switch but when windows wake up from sleep Bluetooth pops up again.

  1. The M.2 slot for Wireless adapter is not the same M.2 slot as for SSD. Usually the Wireless Adapter is installed in separate M.2 slot . In case of your NUC8i5BEH the Wireless Adapter is a soldered down package instead to be installed in M.2 slot as in other NUCs. This probably was done for costs and/or space saving. I don't have NUC8i5BEH, so I can't check what is exactly the function label in Bios. Any way, my advice is similar. The same what you did in bios for disabling the Bluetooth function, do with the WLAN function. Both functions are served by the same adapter.
  2. Did you tried switching the Bluetooth OFF in Windows settings?

In Bios:

Bluttooth disabled

Wlan disabled

 

In Windows 10 I have removed all Bluetooth devices

 

when I scan with my phone, it finds a number of Bluetooth devices without names but only numbers, then the number of devices is reduced.

 

It looks like it's not being turned off properly

because there is still Bluetooth signal, only without device name

 

When I completely turn off the Intel NUC, the Bluetooth devices that I have found earlier in my phone disappeared, I have tested this several times

Hello sneka,

 

For testing purposes, we did the following:

 

1. Disabled Bluetooth in Windows*. We noticed a Bluetooth address was showing.

 

2. Entered BIOS and disabled both Bluetooth and WLAN.

 

Devices > Onboard device Config > Bluetooth

Devices > Onboard device Config > WLAN

 

No Bluetooth address was listed in the device (Phone).

 

3. Turned off the unit. No Bluetooth address was visible.

 

If WLAN is enabled in BIOS, other Bluetooth devices may detect the Bluetooth radio address even if it is turned off in Windows, as addressed by LWAKSMAN. Having said that, we consider this expected behavior.

Is the Bios version perhaps the problem?

This is my bios version:

 

 

Desktop Board NUC8BEB

Bios version: BECFL357.86A.0041.2018.0719.1931

 

 

By the way, is it recommended to update?

Hello sneka,

 

We do not consider this to be a BIOS issue. However, we performed these steps on units with BIOS version 0054 and 0057. We also recommend having your system up to date.

@sneka​,

 

The '2' in your NUC's name is simply an indication that the EU power cord is provided with your NUC (see Intel NUC Power Cord Options for more information).

 

You should be using the BIOS that you found, namely that indicated for the base designation "NUC8i5BEH".

 

Hope this helps,

...S
