The question sounds similar to the unanswered question Is it possible to connect my phone via bluetooth and then call through the computer? and my purpose is similar. However, I was thinking about using WLAN or even the USB to connect my phone to the desktop.
The purpose is to make and take a call via the desktop, using the Bluetooth headset which is attached to the desktop.
What I have tried:
- See if KDE Connect supports this. (This would be ideal, but does not seem to be the case.)
- Check if scrcpy supports this. This seemed like a promising solution, but scrcpy does not transmit audio and usbaudio seems to transmit only from the phone to the PC (have not verified this).
- I saw the similar question How to set up Ubuntu PC as bluetooth headset to attend calls but did not understand how this is supposed to work. (Would both devices be connected via Bluetooth to the desktop?)
I am on Kubuntu, and would prefer a solution working on both 18.04 and 19.10.
