I am interested in knowing if, by sending certain AT commands to the OBD2 Bluettoth adapter (for example the generic ELM 327 Mini) I can "program" this adapter and thus be able to send the PIDs in the format established by CANBus (CAN ID + 8 bytes). Thank you so much.

Of course, that's what these adapters are for. They feature a very large instruction set, but typically you only need a handful to configure them to talk to your car.

Here are some helpful ones:

ATSHxxx sets the CAN Id, ATCAF0 turns off automatic ISOTP formatting. Then you can send 8 bytes of unprocessed data.
