- Fix XSS: escape ASCII output in innerHTML via escapeHtml() - Fix deadlock: use put_nowait() for queue ops under ook_lock - Fix SSE leak: add ook to moduleDestroyMap so switching modes closes the EventSource - Fix RSSI: explicit null check preserves valid zero values in JSON export - Add frame cap: trim oldest frames at 5000 to prevent unbounded memory growth on busy bands - Validate timing params: wrap int() casts in try/except, return 400 instead of 500 on invalid input - Fix PWM hint: correct to short=0/long=1 matching rtl_433 OOK_PWM convention (UI, JS hints, and cheat sheet) - Fix inversion docstring: clarify fallback only applies when primary hex parse fails, not for valid decoded frames Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

<h3>OOK Signal Decoder</h3>
|
|
<p class="info-text" style="font-size: 11px; color: var(--text-dim); margin-bottom: 12px;">
|
|
Decode raw OOK (On-Off Keying) signals via rtl_433 flex decoder.
|
|
Captures frames with configurable pulse timing and displays raw bits,
|
|
hex, and attempted ASCII — useful for unknown ISM-band protocols.
