Hi again @ShangzhiXu

Thanks for the patches, I suggest you can squash or make it 1 PR with many commits and squash later or 1 commit only regarding compiler warning and ISO C/C++ adaptation.

However, as you can see Bosch has something to do with code review and rework from Volvo regarding DLTv2. Another word is we are under freeze so all further fixes shall not be merged before but only after the release of v3.0.1
which shall including dlt protocol v2 adaptation.

Please continue your great work, we would appreciate to see you in further topic of dlt-daemon regarding safe code and bug fix.

Nice weekend
DLT Team

Got it, thanks for the clarification. I’ll pay more attention next time to squashing commits and continue working on this after the release.😀
