我在代码中看见对于ECU和APPID 使用固定大小限制：# define DLT_ID_SIZE 4 Is this a consideration?

ssugiura commented 2 years ago

@m1018 This is a requirement from AUTOSAR to limit the size to 4 bytes: https://www.autosar.org/fileadmin/user_upload/standards/classic/4-0/AUTOSAR_SWS_DiagnosticLogAndTrace.pdf The latest protocol already extended the field to set longer IDs, but currently there's no plan to migrate.
