Bluetooth doesn't work. (hci0: RTL: HCI_OP_READ_LOCAL_VERSION failed (-110))

Bluetooth does not seem to work. The device I have is a hp15-bsxxx series in which both bluetooth and wlan share the same hardware. Currently running linux kernel 5.6.16 on Manjaro.

Attaching the logs here:

I could get absolutely no clue about the error. Some time back earlier on kernel 5.3,15, I managed to get it working using larry finger's rtlwifi but nothing seems to work now.
