Hello everyone,
Since I also have a Medisana body scale (BS430), I tried to set up a RaspberryPi following the instructions. Since I still had an old Raspberry Pi 1 at home, I tried it with this one. I gave the Pi a USB WiFi adapter and a USB Bluetooth 4.0 adapter. I then flashed a current Raspberry Pi OS 12 Lite 32-bit onto an SD card and used it to boot the Pi. The Pi recognized both the WiFi adapter and the Bluetooth adapter. So everything is ok up to this point.
In point 1.3 (Test the connectivity) I had to add the -t random parameter to the gattool command, otherwise I could not establish a connection to my scale. After that the connection worked.
In point 1.8 (Install Pygatt) I received the error message âexternally-managed-environmentâ after executing the command sudo pip install âPygatt[GATTTOOL]â. To fix this, I had to delete the EXTERNALLY-MANAGED file under /usr/lib/python3.11. The pip packages could then be installed.
But now Iâm stuck on executing the Pythen script BS440.py. When I start the script interactively I get the following output:
root@bodyscalepi01:/opt/BS440# python BS440.py
2024-03-29 14:18:25,774 INFO <module> Configured plugins: BS440mqtt

Nothing happens after that. When I then activate the scale, nothing is detected.
If I call journalctl -f in parallel in a second console window, I get the following log entries:
