Bluetooth seems to work here. I needed also to activate the search for BT devices on my phone.
hcitool dev
Devices: hci0 A8:41:F4:A4:03:9D
hcitool -i hci0 scan
Scanning ...
And I can pair the discovered device :
https://simpleit.rocks/linux/shell/connect-to-bluetooth-from-cli/
Maybe to some extend relevant because I did some tweaks as well:
sudo nano /etc/modprobe.d/blacklist.conf
blacklist pgdrv blacklist btusb blacklist btrtl blacklist btbcm blacklist btintel

@tpnthr
That is unfortunate! I suppose that you did a 'systemctl daemon-reload' to reload bluetoothd daemon? BTW I only did the first answer with Add "--noplugin=sap" at the end of the "ExecStart" Line .
AIC8800 Bluetooth is kind of fucked in general, I would look at aic8800-bluetooth.service or the following code.
#!/bin/bash
rfkill unblock all
/usr/bin/hciattach -s 1500000 /dev/ttyS1 any 1500000 flow nosleep
sleep 2
while read -r; do
echo "bt_test > $REPLY"
case "$(tr -d '\r' <<< "$REPLY")" in
"hci recv thread ready (nil)")
echo "Device reset successfully."
exit 0
;;
"dev_open fail")
echo "Unable to open /dev/ttyS1. Is Bluetooth already up?"
exit 1
;;
esac
done < <(timeout 1 bt_test -s uart 1500000 "/dev/ttyS1")
echo "Command timed out."
exit 2
Mmmm.. maybe I did some other stuff too?! I also added experimental support to Ubuntu.
To enable Bluez experimental features in Ubuntu:
-Open /etc/bluetooth/main.conf as root Find the section with :
# Enables kernel experimental features, alternatively a list of UUIDs
# can be given.
# Possible values: true,false,<UUID List>
# Possible UUIDS:
# d4992530-b9ec-469f-ab01-6c481c47da1c (BlueZ Experimental Debug)
# 671b10b5-42c0-4696-9227-eb28d1b049d6 (BlueZ Experimental Simultaneous Central and Peripheral)
# 15c0a148-c273-11ea-b3de-0242ac130004 (BlueZ Experimental LL privacy)
# 330859bc-7506-492d-9370-9a6f0614037f (BlueZ Experimental Bluetooth Quality Report)
# a6695ace-ee7f-4fb9-881a-5fac66c629af (BlueZ Experimental Offload Codecs)
# 6fbaf188-05e0-496a-9885-d6ddfdb4e03e (BlueZ Experimental ISO socket)
# Defaults to false.
KernelExperimental = true
-Reboot or run systemctl restart bluetooth
Don’t skip the last step – if you do, nothing will change.

Looks good actually.
My journalctl and lsmod:
You can try : sudo modprobe rtk_btusb && dmesg | grep rtk
sudo modprobe rtk_btusb && dmesg | grep rtk - worked like magic!!! Thank you
