[PLUG] Need some help!

[Amey Abhyankar]

Thanks.

The Acer laptop has bluetooth version 4.
The Boat 100 wireless earphone has bluetooth version 5.

This seems to be causing the issue.
Imagine the issue of IoT devices like some smart bulbs supporting only
2.4 Ghz wifi frequency. They can not work on 5.0 Ghz wifi frequency.

Wireless headphones have backward compatibility but still.
There are lot of differences between those 2 bluetooth versions. [1]

To verify, can you try it on any other Ubuntu laptop with bluetooth
version 5 if available? [2]

Regards,
Amey.

As you are aware video conferencing is dominantly used for online teaching learning purposes. So we use ZOOM like tools. However we are finding difficulty in integrating MIC with computers via bluetooth connectivity. We tried many things: right from upgrading the system to the latest 21.04 version, changing bluetooth devices, adding available patches but we couldn't make it. So finally I am writing to you. Is there anyone who can help us to solve this problem?. Would someone like to volunteer ? It might be a paid service as well. We will be very thankful to you if you can help us.
