———————————————————————————
I tried using a supported OBD (OBDLink CX) for trip planning with Live Data. I noticed a few things:

• It doesn’t read SOC from the car - I need to set it manually
• I tried calibrating the value by manually adjusting the SOC to match the car’s actual SOC. Even after that, while driving, the ABRP app showed SOC that was less than the actual SOC of the car

I verified that the OBD was connected to ABRP (Green Bluetooth icon in the app). I tried resetting the ABRP app completely.
