Critical bug fixes: - stopJamming() was returning early when jammingEnabled=false, leaving radios in unknown state and breaking capture when jamming was off - stopJamming() now idempotent: always stops noise timer (+ nulls pointer), drives GDO0 low, puts transmitting radios to standby — safe to call anytime - Add capPrevJamming flag saved before stopJamming() clears jammingEnabled; used by stopCapture() and buffer-full handler to correctly restart jamming after capture/replay sessions end Code quality: - capAnalyze() called twice per /api/capture/status request — now called once - Remove unused JAM_NOISE_PATTERN_LEN define (leftover from LEDC era) - Fix stale "LEDC 120 kHz square wave" comment in startJamming() - Web UI: show rec_bits (final stored count) instead of capIdx in Bits cell; progress bar shows 100% when in RECORDED/REPLAYING state Made-with: Cursor
