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.

Please attach dmesg.

Would be great if you elucidated the steps to reproduce in an easy to understand form.

There is no dmesg log file in/var/log/ .

I put forward the problem.

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

There is no problem between a Bluetooth 5.0 tablet (Blackview Tab 8) 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.

Steven G. (Intel Customer Support Technician) said
********************************************************************************
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. 
********************************************************************************

I don't understand the Intel support. The card is equipped with an Intel AX210 chipset and if I understand well, Linux uses the Intel wifi/bluetooth driver of the AX210. No ?
