Blutooth connection - Smart connect

Good afternoon !

Today I install Ubuntu 19.04. Until now, I'm liking of the system. I have problems of audition, and I use hearing aids. Recently I buy an appliance called Smart connect. This appliance serves to do connect with cellphone and notebook. He is an intermediary of connection. And I saw that Ubuntu 16.04 and 19.04 don't do connection with this appliance. Not tested in other versions. I was using version 16.04, and I moved straight to 19.04.
The device is not recognized. I have tested all the settings, and the device is not recognized, including the walkthrough: https://help.ubuntu.com/stable/ubuntu-help/bluetooth-connect-device.html.en. I don't know if there are drives that can help, but I don't think so.

So, as Canonical is always improving the system, I want to report a problem so you can work on improving it. Because, other users can be have some problem like my.
The system is easy to use. So, I think it's something for you to think too.

My regards !
