Bluetooth Peripheral devices could be forced connected

Recently, we found that if the BT device is remove from the BT setting page.

Then, trying to proceed the pairing with nearby PC would be failed.

The failure mode show that the device was forced connected by the previous system but without showing the device info in setting page. And the function could not work properly either.

 

Moreover, we found that if we disable the BT function in the issue platform. The device is allowed to pair with the nearby PC.

 

Do you have any experince and idea of this sympton?

Hello @CY1813

Thank you for posting on the Intel® communities.


In order to understand better this scenario and check this further, could you please provide us with the following information?

1- Please elaborate more on what the specific issue is. Are you unable to connect or re-connect Bluetooth devices to the computer? Please also elaborate more about the reproduction steps. For instance, what do you mean when you said:

  • "(...) BT device is removed from the BT setting page (...)". Do you mean Windows® Bluetooth settings?
  • "(...) if we disable the BT function in the issue platform (...)". Where do you disable this? Could you please provide a screenshot?


2- What are the "Bluetooth Peripheral devices" regarding this request? Please provide maker, model, part numbers, etc.

3- Is the Intel® Wi-Fi 6 AX201 the original wireless adapter that came pre-installed on the system? Or did you install/integrate on the computer?

4- Was this working fine before or is this issue happening since the first day that you have the device(s)?

5- If this worked fine before, do you remember if this issue happened after a new Windows update or Wireless/Bluetooth driver update? Also, does the issue happens if you use the customized drivers provided by the computer manufacturer (OEM) Lenovo*?

Hi @AndrewG_Intel ,

Please kindly check my response below:

1- Please elaborate more on what the specific issue is. Are you unable to connect or re-connect Bluetooth devices to the computer? Please also elaborate more about the reproduction steps. For instance, what do you mean when you said:

Reproduce Step:

  1. Paired the device with first PC.
  2. Remove (Disconnect) the device from the PC.
  3. Then pair the PC again. -> issue happened. (Based on sniffer device is connected, but not show in the BT setting page)

or

  1. Paired the device with first PC.
  2. Remove (Disconnect) the device from the PC.
  3. Paired with nearby PC. -> Issue happened. (Based on sniffer, the devic is connected by first PC again and without show on BT setting page.)
  4. Turn off BT function by toggle the BT button in BT setting page.
  5. The device is allow to enter pairing mode again then paired with nearby device.

However, there is failure rate. But it is easy to reproduce when frequently pair.

When issue happened in the first PC, we would need to restart the system or go to device manager to disable BT chipset function.

  • "(...) BT device is removed from the BT setting page (...)". Do you mean Windows® Bluetooth settings? -> YesCY1813_0-1634537479289.png
  • (...) if we disable the BT function in the issue platform (...)". Where do you disable this? Could you please provide a screenshot?

       -> The Bluetooth button in the screenshot

 

2- What are the "Bluetooth Peripheral devices" regarding this request? Please provide maker, model, part numbers, etc.

-> Stylus (Active Pen), such as Dell PN579X, HP Active Pen G3

3- Is the Intel® Wi-Fi 6 AX201 the original wireless adapter that came pre-installed on the system? Or did you install/integrate on the computer?

-> Yes, it is original adapter.

 

4- Was this working fine before or is this issue happening since the first day that you have the device(s)?

-> Yes, it was fine.

5- If this worked fine before, do you remember if this issue happened after a new Windows update or Wireless/Bluetooth driver update? Also, does the issue happens if you use the customized drivers provided by the computer manufacturer (OEM) Lenovo*?

-> Actually, the issue seems not related to the specific platform directly.

-> We also could reproduce in other platforms.

-> The faliure mode seems occured when OS update and BT driver update.

-> Unfortunally, I could not remember which version it start to happened.

-> I also test it with other OEM platform, HP, Dell and MSFT. Most of them are above 21H1.

Hello CY1813

Thank you very much for your response and for the details.


Before we move to next steps, we would like to recommend you a Clean Installation of Wireless and Bluetooth Drivers using the latest Intel® Drivers (this is in case you haven't tried process yet). We know this is a basic step but we just want to make sure the drivers have been installed using this process. It is important to install both drivers as they are related and both components are integrated in the same card. You may find the links below:

To verify the Bluetooth driver was properly installed, you may refer to (1) Windows* > Apps > Apps & Features, scroll down and look for Intel® Wireless Bluetooth; or (2) Windows > Device Manager > Bluetooth > Properties > Driver tab.

Please confirm once the drivers are installed using this method and if the behavior persists or any other (different) behavior.


Also, since you mentioned that "you could reproduce in other platforms" and from different OEMs, could you plese confirm if this issue is occuring on an Enterprise Environment?

How many computers with Intel® Wi-Fi 6 AX201 do you have in your environment? And how many of them experience this issue?

Couldl you please share some examples of the specific device models of the other OEM platforms Dell*, HP*, etc?


Best regards,

Andrew G.
