After experimenting with commands (I think)
mcetool -searly
mcetool -senable
mcetool -sdisable
due to a bluetooth error, my Gemini PDA SFOS 4.x got into a state that it consumes the battery very quickly. Process consumption indicated
that this was probably due to systemd-journald. Can anyone advise me how to fix this or what is the cause, please?Edit: Previously, the Gemini battery lasted one week in standby mode. Now drop from 70% to 40% in two hours!
I would try to find out first what journald is attempting to achieve.
journalctl -f
(as devel-su) might throw an enormous amount of messages, there should be a hint what’s going on. I don’t think that journald is the problem by itself.
On my Xperia X I found journald sometimes crashed, I guess due to temporary overload…
Anyway, you normally can check, stop, start and restart systemd-journald like any other service:
systemctl status systemd-journald
systemctl restart systemd-journald
but I doubt it’s helpful.
BTW: there’s no option “enable” or “disable” with parameter -s for mcetool, afaik. The options are “enabled” and “disabled”
Thanks for reply.
In journalctl -f repeated error:

I don’t know what transfer ACK error means. It is true that I tried to transfer files via BT from Xperia X to Gemini and the transfer was not successful. Is it possible to stop it?
The mcetool commands with -s are described here
The state of the processor adjusted when I stopped BT service
systemctl stop bluetooth.service.
What next? Where are the data in progress for BT transmission? I should probably delete them or cancel the process that is trying to transfer them. But how to do it?
It seems to stop | start BT service helped.
