I was able to fix the issue.
By following the guide here :
I had to add a Bluetooth dongle (USB 2 on RPI4; BLE4.0 ; no config).
By following the commands in the console I am able to add devices WITHOUT any wifi router or any phone or app.
Everything on the computer
I am super happy.
- The OPTBR is now displaying correctly the devices over the topology (which was not the case with google nest pro config)
