Driver not work #864

Closed DaweeCZ closed 8 months ago

DaweeCZ commented 8 months ago

Describe the problem

During the initial installation on the beta version of Venus OS 3.20 ~ 16, everything went fine, except that the BMSs kept connecting and disconnecting via Bluetooth, so I uninstalled the installation according to the instructions. Now, I wanted to reinstall the driver again, and since then, it hasn't been working. During the installation, it reports an error with a non-existent folder /service/gui/, and in the BT log, it throws 'ERROR:SerialBattery:Unexpected err=ModuleNotFoundError("No module named 'dbus_fast._private.constants'"), type(err)=<class 'ModuleNotFoundError'>.

Driver version

Venus OS device type

But at least we can see it in the logs... Please install the latest nightly from the dev branch. There the error is fixed. Else see https://github.com/Louisvdw/dbus-serialbattery/issues/785

DaweeCZ commented 8 months ago

Oh, I apologize, I overlooked this.. I installed the latest nightly dev, and now the log looks like this:

Did you reboot after install, right?

Seems that dbus-fast is still missing. Try to install it manually and see if it throws an error.

export SKIP_CYTHON=false
pip3 install dbus-fast
DaweeCZ commented 8 months ago

Yeah, rebooted after every install and uninstall previously. 

root@einstein:~# export SKIP_CYTHON=false
root@einstein:~# pip3 install dbus-fast
Requirement already satisfied: dbus-fast in /usr/lib/python3.8/site-packages (2.14.0)

And still same errors on log.

mr-manuel commented 8 months ago 
export SKIP_CYTHON=false
pip3 install dbus-fast==1.91.3
DaweeCZ commented 8 months ago

Perfect! Now it works! Thank you very much!

mr-manuel commented 8 months ago

This is very strange. Sometimes it works, sometimes it does not work with the current dbus-fast version...

DaweeCZ commented 8 months ago

Let me get back to the topic; I had to reinstall the new DBUS 2.14.0 because I found that ESS stopped functioning, not responding to commands like 'keep the battery charged' Hopefully, the RS485 - USB converters will arrive tomorrow, so I'll try connecting via cable to the new DBUS.

There was also an issue where one of the two BMS froze and stopped updating via bluetooth; Cerbo restarted twice overnight, I'm not sure why. Since I paused the driver, everything has been fine.

mr-manuel commented 8 months ago

The cerbo most likely restarts because of overload, then the watchdog triggers a reboot.

DaweeCZ commented 8 months ago

Yes, I think so too because during Bluetooth communication between two BMSs, even the remote console was quite sluggish. Once the converters arrive, I'll try to set it up again, hoping it'll work better than the Bluetooth connection. I'll be connecting a total of 4 BMS.

DaweeCZ commented 8 months ago

So the converters arrived, I have it set up now in the classic way: BMS -> JK 485 adapter -> 485 to USB converter into the USB hub. After connecting and reinstalling the drivers on dbus-fast 2.14.0, nothing happened. I installed dbus-fast 1.91.3, reinstalled the driver again, and the BMS systems logged in. Then I installed dbus-fast 2.14.0, and the BMS systems are still connected. It looks like it's working. Rebooted after every install.

mr-manuel commented 8 months ago

dbus-fast is not needed for the serial connection.

DaweeCZ commented 8 months ago

So I'm not sure why the BMS systems didn't log in right after installation and restart, but only after reinstalling to dbus-fast 1.91.3, but I don't have to worry about that now. The main thing is that it's working now. The rest of the cells should arrive within a month, so then I'll set up the driver to aggregate the batteries into one. Thanks for the support!

mr-manuel commented 8 months ago

You're welcome.
