Title:
RTL8723bs bluetooth not working on 20.04
Status in linux package in Ubuntu:
Confirmed
Bug description:
I have Ubuntu 20.04 installed on atom-based tablet ACER Aspire Switch 10. And
bluetooth does not work. In fact it looks like ubuntu does not recognize
bluetooth HW at all. But the system does have bluetooth module which under
windows is recognized as RTK8723 (ACPI\RTK8723\some-id)
At the same time WiFi works without issues (the same module, if I am not
mistaken).
$ lsb_release -d
