I got the KUULAA OBDII. It is connected to the DUDU OS, but there is no data showing in the status bar or in vehicle information app. I test it with a third party app, and it works fine.
My car is 2007 Toyota Camry Hybrid.
Head unit 13” FYT.
OS DUDU 7862 V240927.
Kindly, if someone has a solution for this issue please share it.
