MB Asus B250M

Wi-Fi/Bluetooth card : EDUP LOVE EP-9651GS (chipset Intel AX210), Bluetooth 5.3

Samsung S7, android 8.0, Bluetooth 4

openSUSE Tumbleweed

Firmware date : 20220902 (date of the package "firmware all")

I don't use Wi-Fi. Just for a backup solution. I checked Wi-Fi works well.

At the PC, just disconnect the smartphone after pairing.

Wait 5 mn or more.

At the PC, connect the smartphone. The connection fails.

I did some experiments with Clearlinux and Fedora. With the two OS, I can reproduce the problem.

More info :

At the PC, I disconnect then reconnect the smartphone. The connection succeeds.

At the PC disconnect the smartphone.

Wait for 5 mn or more.

Thanks in advance

Hello promeneur,

Thank you for posting on the Intel® communities.

In order to better assist you, please provide the following information:

What driver version are you using for the wireless adapter, and where are you downloading it?
Did the issue start after any hardware upgrade or driver/OS update?

Best regards,

>> where are you downloading it?

I downloaded nothing. The driver is installed by the OS openSUSE Tumbleweed.

>> What driver version are you using for the wireless adapter ?

In the file boot.msg I found this

Since yesterday, I have put forward.

It's not a problem with chipset intel AX210 (Bluetooth 5.3).

There is no problem between a Bluetooth 5.0 tablet (Blackview Tab  and a PC equipped with Bluetooth 5.3.

There is a problem between a Bluetooth 4.2 smartphone (Samsung S7) and a PC equipped with Bluetooth 5.3. 
You can't connect the smartphone from the PC. 
You can only connect the PC from the smartphone then immediately disconnect/reconnect the smartphone 
from the PC to get all the protocols, HSP and A2DP.

What do you think ?

Steven_Intel · ‎09-28-2022

Thank you for all the information provided.

I am going to research about this, based on the information provided. As soon as I have an update, I will let you know.

Hello promeneur,

Due to the fact that you are using a wireless card designed by a third-party manufacturer, and none of our drivers are being used, our best recommendation is to contact EDUP support for further assistance.

Please keep in mind that this thread will no longer be monitored by Intel. Thank you for your understanding.

Best regards,

Steven G.

Intel Customer Support Technician.
