UDS or OBDII protocol

[Daparrag]

Hi All

Hope you are doing well and congrats for supporting automotive protocols.

My question is the following:

There is a clear difference between what is UDS and OBDII protocols as is pointed in the following article https://incardoc.com/en-us/article/the-difference-between-uds-and-obd-protocols/

If I am not wrong your implementation only support OBD messages. is this true?
if so how can I send standard UDS messages? do you have any example?
if not how can adapt your implementation for that? there is a easy way to do it.

hope you can respond soon.

Cheers,

I have the same problem, I cannot find the UDS service in the project, for example: 0x19 read DTC Information

This library is more OBDll library than UDS. If you want to have standard UDS, as I presume you do, you will end up modifying the source code to add the functionality you need.

The isotp library is great however is quite limited. I recommend you to make a look of the isotp module implemented on Linux. Isotp will package your UDS frame and send it over can.

If you think about it, you don't really need this lib for UDS. You can instead get some ideas and implement by yourself.
