Also, what do you mean by "couldn't be read"?
What PC connection are you trying to use (Ethernet to M130 ECU? USB-to-CAN on M400/M800 ECU? Ethernet to CDL3?).
You need to describe how your system components are connected so that we can help you.
Thanks for your reply !
We use STM32 to connect with M84 by wireless CAN communication. We put wireless serial port in M84 CAN port and STM32, in this way they are connected.
We receive many data from ECU, like the battery voltage, the engine temperature. But the GPS and the steering angle store in CDL3, and we can't output them through CAN. If it is possible to output them ?
Look forward for your reply !
