Summary
Fetches segments by id (0..ACCUCHEK_SEG_MAX, default 3) and reads glucose only from segId=0.
Extracts meal tags from the CMeal segment (segId=3) using the observed 10‑byte record format.
Avoids false positives by decoupling tag parsing from glucose records and emitting JSON after all segments are processed.
Technical details
CMeal record signature: byte7=0x00, byte8=0x72, tag code in byte9.
Tag mapping:
0x4C → Antes comida
0x50 → Desp. Comida
0x54 → En Ayunas
0x74 → Al acostarse
Notes
“Otro” does not appear in the observed CMeal dumps, so it cannot be inferred from the device data captured so far.
If you want it shortened or more formal, tell me the preferred style.
