You could try to install an older version of bleak like this: |

Seems that something is broken in your installation. Is this a fresh install? This should fix this error, but probably a new one arises after.

Hey Manuel, you are right, I also got an error message when I try to install the "dataclasses" I absolute agree with you, seems to be a problem with the installation. The system is a Victron MP2-GX. If there is a way to do a complete new installation I don´t know it. I only now how to update the Venus OS and the VE.bus firmware.

Google is your friend: 18. Reset to factory defaults procedure |
I agree ;-) but I don´t have a Cerbo. But I will figure out how to bring my MP2-GX back to factory defaults - Then I try the serialbattery BT connection with the official Venus OS. Thanks |

This is the same for all GX devices. Edit: Obviously not for a Raspberry Pi. |

Describe the problem
Hi,
I try to connect my jkbms via bluetooth to my Multiplus 2-GX because the cable connection sometimes "lost" my jkbms.
The installation log showed me some errors. All log files are attached.
I also tried to install "opkg update" "opkg install python3-misc" & "python3-pip" by hand - same error message.
Not sure if the beta firmware (v3.20~34) of my MP2-GX causes this problems.
It would be very kind of you if you could have a look and help me here.
Thank you very much in advance
Alex
