DLT Viewer license MPL2 vs AUTOSAR

[pdrunin-qs]

dlt-daemon is using an AUTOSAR standardized protocol "https://www.autosar.org/fileadmin/standards/R22-11/CP/AUTOSAR_SWS_DiagnosticLogAndTrace.pdf" so it obliges actually the AUTOSAR license policy as well and not only the MPL2, i.e. altought dlt-daemon is marked as MPL2 it still can not be used in any SW without a License from Autosar, is this really the case ?

basically this is the Disclaimer from Autosar regarding the standardized protocol that is being used by dlt daemon:

Hi @paulboyes ,

I was intending to use the dlt-daemon + dlt viewer outside of AUTOSAR/Automotive industry, in UAV area for debugging purposes, as I liked the idea how we could dynamically change the tracing levels for apps/ids for example, etc, but after double checking the license requirement now took different open source projects, as this basically seems not to be freely usable i.e. a paid AUTOSAR license is required, and decided to start this discussion in order to make this more transparent, so it is faster to understand from others, or I could got it wrong too.

I am not having much expericence on the license issue, can you kindly explain a bit about the conflict, and how we could support you here? I got this from Chat GPT explanation:

Using dlt-daemon code for personal experimentation, learning, or internal development may fall under MPL2 and informational use.

Integrating dlt-daemon into commercial software without an AUTOSAR license could be a copyright violation, because you are implementing the AUTOSAR DLT protocol.

Payment/licensing obligations are imposed by AUTOSAR for commercial use, not by MPL2.

You would need to contact AUTOSAR to clarify licensing requirements for commercial deployment.
