it is not an expected behavior. Can you create a btmon trace for this and see what error code we get on the HCI level.

Without any kind of analysis this sound like a race condition in the disconnect handling where the connection is not fully terminated and you try to re-connect too quickly.

What kernel version is this? And as usual the first question, do you still see this behavior with a bluetooth-next kernel?

Regards

Marcel
