I want to connect my bluetooth earphones to my laptop so I followed the instructions given on the website. I installed bluez, enabled the required services and checked the rfkill. Still it is not working so the i  checked dmesg and I got the following error.

[ 5.121228] bluetooth hci0: Direct firmware load for qca/rampatch_usb_00000302.bin failed with error -2

[ 5.121231] Bluetooth: hci0: failed to request rampatch file: qca/rampatch_usb_00000302.bin (-2)

[ 81.840100] bluetooth hci0: Direct firmware load for qca/rampatch_usb_00000302.bin failed with error -2

[ 81.840103] Bluetooth: hci0: failed to request rampatch file: qca/rampatch_usb_00000302.bin (-2)

I dont know how to fix this. I switched back to Arch Linux a while back because of this and I dont get this error there.

uname -r

5.0.9_1

Please tell me the solution.

# bluetoothctl

[bluetooth]# scan on
