AC500 bluetooth fails

Problem with bluetooth:
After many days time bluetooth disconnects by Bluetti AC500 somehow automatically caused by whatever.
Trials to reconnect by client end up in connection flapping between connected and disconnected.
Can only be solved by switching off Bluetti - but:
While in operation as central 230V supplier this means that also external 230V has to be disconnected as well as solar input for a machine that serves as “user defined UPS”.
This is a bad behaviour of a machine that is the central failover power supply of an internal 230V area.
There should be either a possibility to only restart bluetooth on Bluetti AC500 or a more stable bluetooth system that does not get stuck after a while.
This is a proposal to enhance the Bluetti AC500 accordingly.
