Acer Aspire E15 laptop (model number E5-573-54ZV) with Windows 10 and Bluetooth 4.0 adapter out of the box. While using Windows, I'm able to use the Bluetooth adapter.
I've installed Ubuntu 16.04 in dual boot. While using Ubuntu, the Bluetooth adapter is the only piece of hardware that does not work.
I've already tried other Q&A here at Ask Ubuntu, but all of them refer to different versions of Ubuntu and/or different Bluetooth adapters. For me, it seems like Linux is not even seeing my laptop's Bluetooth adapter.
A report made using AIDA64 for Windows shows:
04CA 3014 Qualcomm Atheros Bluetooth 4.0
Is there any way I could make that Bluetooth adapter work on Ubuntu 16.04?
I don't know if that helps, but my laptop also has an Atheros Wi-Fi adapter, which the AIDA report shows as
Atheros AR9565 802.11b/g/n Wireless Network Adapter, a PCI device with ID
