Car model(year): Kia Sportage PHEV (NQ5)
Phone model(Android version): OnePlus Nord 2 5G (Android 13)
Carsifi adapater firmware version: 1.10.0

Most of the time my phone will not connect to Carsifi at first attempt. Sometimes it suffices to toggle my bluetooth off and on again.
If that doesn’t work I have to select my carsifi device in the bluetooth menu and pair again.
