Some cars need to enter PINCODE, i.e. a 4-digit or multi-digit authentication code before connecting to verify the connection, which is an old Bluetooth protocol.
DM13 uses Qualcomm's Bluetooth chip, and Qualcomm has closed the support for PINCODE in Bluetooth version 5.2 and above. So DM13 doesn't support the connection of this program.
Why do some new energy cars need PINCODE connection?
You can only ask the car manufacturer about that!
