Payload formats for LPWAN Applications
summary
Compares concrete payloads and sizes: JSON is human readable but bloats bytes, a CSV example hits ~20 bytes, a compact raw binary fridge sensor frame uses ~5 bytes, a Protocol Buffers value can be encoded in 1–2 bytes, and an efficient XML binary sample is ~15 bytes. Notes about tooling and adoption: 200 devices integrated so far, uses protocol buffer and a custom LPP-style format, recommends self-describing IDs per field, avoid ad hoc text strings, and expect payloads to evolve.
