Hi @syssi - interested to know where you obtained those bitmasks?

Can confirm that I have installed your mods and on my JK 8S bitmask now reads '0' Screenshot 2022-05-16 103731

I've extracted these strings from the android app.

@Jalle19 If you are aware of more bit flags I would be happy about your support!

Not really, I just stumbled upon "current sensor anomaly" when connecting a charger to the battery while discharging. Learned that the ESP can be forced to disconnect from Bluetooth to allow the official app to find the BMS 👍

Does the status bits change? https://github.com/jblance/mpp-solar/issues/460#issuecomment-1973313087
