What sort of tools did it use? I suppose the path mine took may have been a dead end. The Tuya app (I was also using decompiled APK) downloads the BLE definitions on-demand and weren't embedded in the app. It wanted me to capture traffic on a device with the app. I punted but plan to resume with an emulator setup or real device connected with adb.
I did consider naming, but they were very responsive to the disclosure and I was not entirely familiar with potential legal implications of doing so. (For what it's worth, it is not Luuna)
It's good that they were responsive in the disclosure, but it's still a mark of sloppiness that this was done in the first place, and I'd like to know so I can avoid them.
