Corrected the parsing of NL43 DRD (Dynamic Range Data) and DOD (Data On Demand) responses according to the NL43 Communications Guide. The previous implementation incorrectly mapped d0 (counter field) as a measurement. Changes: - Updated DRD/DOD parsing to skip d0 (counter: 1-600) - Correctly map d1-d5 to lp/leq/lmax/lmin/lpeak measurements - Added inline documentation referencing DRD format specification - Included database migration script to revert incorrect field names DRD format per NL43 spec: - d0 = counter (1-600) - NOT a measurement - d1 = Lp (instantaneous sound pressure level) - d2 = Leq (equivalent continuous sound level) - d3 = Lmax (maximum level) - d4 = Lmin (minimum level) - d5 = Lpeak (peak level) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
