Decode protobuf without proto files

Question

I would like to decode protobuf data and running into some decoding challenges.

1> Example of the protobuf data: 0a06282c0241057a10011805220d080510bea3f493062a03010c1628f1a6f493063002382b4001481482010f383634333233303532343736343839

2> Decoding online (e.g. via https://protobuf-decoder.netlify.app/) works fine

3> Decoding via protoc.exe is not working

• protoc.exe --decode_raw < measurement01_bin.txt (have tried HEX or BIN as input)
• Result: Failed to parse input.
• Question: What am I not doing correct?

---

4> Further I would like to add protobuf decoder in a cloud solution (in-memory) and ideally not be dependent on protoc (in my environment it is almost impossible to run an exe). So I am looking for a stand-alone parser / raw decoder in run-time and not using proto files.

• Question: Do you have idea for me on how I could set this up?

Thanks a lot
