Already tried pip install --upgrade splatplost to the newest version, but didn't help.

Ok, fixed by disable bluetooth suspend setting in /etc/bluetooth/main.conf, [Policy] segment, remove SuspendPolicy and AutoEnable setting if exist.

Some bluetooth chip doesn't support them, and will cause bluetooth malfunction.

and restart bluetooth command
systemctl restart bluetooth

Sometime need restart few more times to take effect, root permission required for this operation.
