As reliable as it is, users occasionally run into hiccups with the Delphi 100251-AliExpress
This is almost always due to power fluctuation from the OBD port. Use an OBD-II extension cable with a direct 12V power injector. Also, ensure your laptop’s Bluetooth adapter is not going into “power save” mode. Go to Device Manager > Bluetooth Adapter > Properties > Power Management and uncheck “Allow the computer to turn off this device.”
