JBDBMS BLE - Not connecting on Venus OS >= 3.20~1

[petertmac]

Describe the problem

I recently updated my VenusOS after an SD card failure. I installed the latest VenusOS release and V1.0 of SerialBattery. I have two JBDBMS connected to my Pi via USB cables. Prior to SD failure both BMS's show up in VenusOS. After update can only see one BMS. I then decided to try the BT connection on one of the BMS's. Still can only see the BMS connected via USB cable. The other BMS has the BT dongle reinstalled and I can see it in the XiaoxiangBMS app. I just installed the nightly build and have the same issue.

Driver version

1.0.20231117dev

Venus OS device type

Raspberry Pi

Venus OS version

v3.13

BMS type

Smart BMS (LLT, JBD, Overkill Solar)

Cell count

4

Connection type

Bluetooth

After installing Ver: 1.0.20231117dev, I decided to disconnect the bluetooth dongle and reconnect the Serial Adaptor and I can now see both batteries in VenusOS. However the Bluetooth issue remains unresolved.

[Dajestia]

same problem, but with VenusOs v.3.20-35 + Cerbo GX + nightly/dev

[mr-manuel]

You could try to install all modules which are not found with pip3 install modulename, but normally this looks like a broken system. At least it was in other issues.

[Dajestia]

returning the fw 3.13 works all right

[Dajestia]

Nothing to do, I tried to install the modules as suggested, to update to the latest nightly but still does not work. With the FW 3.20-37 does not want to work.
If I go back to FW 3.13, everything works on the first shot.

[AlexdeKairos]

Same here. None of the 3.20 betas work. Same installation errors on 3.20 but 3.12, 3.13 and the new 3.14 works perfect for me on 1.0.20231117dev.

Something wrong with Bluetooth connections on the new 3.20 betas.

For me the title of the issue should be: JBDBMS BLE - Not connecting on Venus OS 3.20-35

[coca7]

I can't connect the JBDBMS by bluetooth either. I tried last week, and had more success than in the past but still could not connect. I also found it odd that I could see the bms bluetooth using bluetoothctl in Venus OS, but not on my Mac (bluetoothutil on Mac) or linux machine. However, I can connect to the BMS on Mac through the Smart BMS app. I reconnected all my BMS on USB, but I have attacked the log from one of them.

[mr-manuel]

@idstein have you the same problem with Venus OS 3.20~*?

[idstein]

Yes, have had the same pip installation problems with bleak building dbus-fast.

Workaround for me was to force reinstallation of python3-misc that contains dataclasses.

A simple --force-reinstall failed due to file overwrites (conflict with python3-core, python3-netclient, python3-multiprocessing)

opkg install --force-reinstall --force-overwrite python3-misc

[mr-manuel]

Any update from you guys that have problems? @petertmac @Dajestia @AlexdeKairos @coca7

[petertmac]

I stayed with the wired connections which work. It is difficult to swap the cables due to BMS locations, so have left it for the moment. One battery I can give a custom name. The other doesn’t give the option in the GUI.

[mr-manuel]

One battery I can give a custom name. The other doesn’t give the option in the GUI.

Without further informations is hard to help. Please open a new issue for that.
