dbus-serialbattery Permission denied

[RichieS67]

Dear all!
Today I updated my GX with the new Firmware 3.66 and the dbus-serialbattery with the latest FW v2.0.20250729, too.
I'm using PuTTY and I'm logged in as Superuser with the right Root-password.
Update was without any problems but when I want to modify the settings of the config.ini with "/data/apps/dbus-serialbattery/config.ini" I allways got the following message: -sh: /data/apps/dbus-serialbattery/config.ini: Permission denied
I modified my config and want to upload it from my PC.
Any idea what's the problem? Your help is very appriciated!

Well, I’m no expert here, but you could try starting your line with nano. I access mine by typing:

nano /data/etc/dbus-serialbattery/config.ini

Thank you very much for your help but it only got the message that the directory "/data/etc/dbus-serialbattery" doesn't exist.

This path is for driver version smaller then v2.0.0. With v2.0.0 and after the driver is in apps not etc. Everything is in the documentation.

[mr-manuel]

Just follow the documentation and copy the whole command not only a part of it. What you are doing is executing the config file, which will not work. You need to execute a text editor and append the file path to it. In less words, just add nano and a space before the path of the config file.

Ah you have a Daly. Try to increase the polling intervall. Maybe 2 is enough, else increase until 5.

[mr-manuel]

Yes, the value is the poll interval in seconds. Means the data is fetched every x seconds from the battery. See also:

• venus-os_dbus-serialbattery/dbus-serialbattery/config.default.ini

  Lines 492 to 497 in bbbca0f

  	; BMS poll interval in seconds.
  	; If the driver consumes too much CPU, you can increase this value to reduce the refresh rate
  	; and CPU usage.
  	; Default for most BMS is 1 second; some BMS may have a higher value.
  	; Leave empty to use the BMS default value; decimal values are allowed.

Still not solved, that you deleted your comment? 😅

[RichieS67]

I thought it was solved, but then I had a few errors again with version 3. I'll keep an eye on it and let you know...

[RichieS67]

I've tried a lot today, but the error still persists. I was able to take a screenshot.
Maybe you know what's causing the error?!?!
