I found the open source Valetudo (https://github.com/Hypfer/Valetudo) project quite interesting, as it sits between the vendor firmware and (cloud) connectivity. The project is made possible due to Dennis Giese's research.
It currently supports Dreame, Xiaomi, Roborock and some others. But not Ecovacs.
And not sure it prevents this type of Bluetooth vulnerabilities.
