IOT component firmware update to version 9014.12 = bluetooth connection is extrem unstable

[alterHase77]

I updated my AC300 from 9014.10 to 9014.12 because the bluetooth connection was not that stable. Using the newest version with NimBLE library was ok but i was hoping the firmwareupdate at the bluetti would made it perfect :-)
After the update the bluetooth connection is extrem unstable, near to unusable.

Is there anyone with the firmware 9014.12 and a stable bluetooth connection?
As soon as my ESP32S3 connects via bluetooth the connection is interrupted after some seconds or at best after some minutes.
Before i updated my Bluetti to 9014.12 the connection was stable for hours or even for a day or two.
It seems to me like my ESP is overloaded and restarts because of this. Any ideas to solve this issue?

I've never had a version of the AC300 firmware that didn't occasionally time out or get stuck with Bluetooth, and v9014.12 certainly hasn't seemed any different. Looking at my logs (I'm using bluetti-mqtt on a Raspberry Pi), I can see several periods per day where it automatically disconnects and waits to reconnect because it keeps getting back bad data. With bluetti-mqtt I have limited control over the Bluetooth stack - I'd always hoped once I had the time to mess around with the ESP32 that I could get it to be smarter about reconnect.

I have the same issue of @alterHase77 on my dad's AC300.
On my AC300 instead I have a complete different IOT version which is v9041.03 ant the Bluetooth is super stable and I don't have any problems with the ESP32 Wroom for weeks!
I don't know why the IOT version appears so different even though both AC300 has been updated.
Anyway on my dad's ESP32/Bluetti, I'll try to add an ESP32 reset after a few hours. Let me know guys if you found a different workaround.

I switched from the esp32 to a raspberry pi and the problem is gone.

Thank you @alterHase77 so you are not using the ESP32 anymore?
Are you using an Home Assistant plugin that uses the raspberry pi bluetooth directly? If yes, which one?
Thank you

@Spettacolo83 No.
Yes, HA via MQTT and bluetooth to the Bluetti. I use the Bluetti to MQTT addon

Thank you @alterHase77 do you have a link of that, please?
