How do I decode a raw IR capture?

Paste the raw microsecond timings from a Flipper Zero, IR receiver or any learner into the READYWARE Signal Editor. It identifies the protocol and shows the device and function in the Signal Stats panel — NEC, Sony, Panasonic, RC5, RC6, JVC, Sharp, Denon, Denon-K or RCA — then Rebuild Clean regenerates the code at perfect timing.

Can it decode Sub-GHz RF signals and Flipper Zero .sub files?

Yes. Open the RF tab and paste a Flipper Zero .sub file (RAW or protocol form) or a raw 433/315/868MHz OOK capture. The READYWARE Signal Editor decodes eleven fixed-code protocols — Princeton/PT2262/EV1527, Nice FLO, CAME, Holtek HT6P20, Ansonic, Gate TX, Linear, SMC5326, BETT, Doitrand and Intertechno (Nexa / KlikAanKlikUit / Elro) — and shows the key and bit length. It auto-picks the tightest-fitting protocol so it will not confuse, say, a CAME remote for a Princeton one. You can generate any of these from a hex key and export as a Flipper .sub file, an Arduino rc-switch sketch, an ESPHome remote_transmitter raw block, BroadLink or raw microseconds. Every protocol was validated against the Flipper Zero firmware timing constants. Rolling codes — KeeLoq, Chamberlain/LiftMaster Security+ 1.0 and 2.0, Somfy RTS, StarLine and Nice FloR-S — used by modern garage doors, blinds and car fobs change on every press and are detected and clearly flagged as non-clonable.

How do I convert a Denon or Marantz RCKSK code to Pronto Hex?

Paste the Denon RCKSK code (for example RCKSK0410348) — or the raw binary bit rows straight from Denon's remote-code PDF — into the READYWARE Signal Editor. It renders the Denon-K (Kaseikyo) signal and outputs Pronto Hex, Flipper, BroadLink and Home Assistant with the real button names. Denon 15-bit RCSHP codes work the same way.

What IR protocols does the READYWARE Signal Editor support?

It encodes and decodes NEC, NEC Extended, Samsung, Sony SIRC, RC5, RC6, Panasonic (Kaseikyo), JVC, Sharp (also used by Mitsubishi), Denon, Denon-K (Kaseikyo) and RCA — each validated against real captures. It also reads and writes Pronto Hex, BroadLink, Flipper Zero, LIRC, Global Caché, GIRR, Arduino and Home Assistant.

How do I convert Pronto Hex to BroadLink?

Paste your Pronto Hex code into the READYWARE Signal Editor input box. It is automatically detected and converted. Click the BASE64 output tab to see the BroadLink Base64 format, or the BL HEX tab for BroadLink space-separated hex.

How do I convert Flipper Zero IR files to BroadLink?

Drop your Flipper Zero .ir file onto the import area in the READYWARE Signal Editor. All buttons are automatically detected. Select any button to load it, then click the BASE64 tab to get the BroadLink Base64 format.

What is the best free online IR signal converter?

READYWARE Signal Editor at readyware.net/signal-editor.html is the best free online IR and RF signal editor and converter. It supports 14 output formats, live waveform visualization, pulse editing, Sub-GHz RF decode and generate (Princeton / PT2262, Flipper .sub), Bluetooth mapping, and requires no account or download.

How do I decode a BroadLink Base64 IR code?

Paste your BroadLink Base64 string into the READYWARE Signal Editor. It is automatically detected and decoded into pulse timings which are shown in the live waveform. The signal stats panel shows the protocol, carrier frequency, address and command.

Is there an online alternative to IrScrutinizer?

Yes. READYWARE Signal Editor is a free online alternative to IrScrutinizer that runs in any browser with no Java or download required. It supports all major IR formats, live waveform analysis, protocol detection, pulse editing, and more.

Tips for Stubborn IR Signals

🕶️

The Sunglasses Trick

Place sunglasses over the IR receiver on your BroadLink device. The tinted lens reduces ambient IR noise and helps weak or distant remotes learn consistently. Works especially well in brightly lit rooms.

🤲

Cup Your Hands

Cover both the remote emitter and the BroadLink receiver with your hands or a dark cloth. Fluorescent lights pulse at 60Hz and interfere with 38kHz IR. Blocking ambient light can fix learning failures instantly.

📏

Distance Sweet Spot

Not too close, not too far. 6–12 inches is ideal. Too close overdrives the receiver and clips the signal. Too far and it's too weak. Point the emitter end directly at the BroadLink — not at the phone.

🔋

Fresh Batteries

Low batteries change signal timing. A remote on weak batteries may learn a subtly wrong signal that works unreliably. Replace batteries before learning critical signals — especially AC unit remotes.

🔁

Try Three Times

If the first learn attempt captures a noisy signal, repeat learning 2–3 times without stopping. Compare the waveform — a clean signal has consistent pulse widths. The best attempt is obvious on the waveform.

❄️

AC Unit Remotes

AC remotes send very long signals (100–300+ pulses) encoding the full state of the unit. Hold the button for the entire signal — until the BroadLink LED finishes its flash sequence. Releasing early cuts the signal.

🎯

Edit Corrupt Signals

Load the signal into the editor. Click any pulse in the table to edit it. A good NEC signal has a 9000µs AGC mark, 4500µs gap, then consistent 560µs marks. Fix outliers and use Normalize to clean the whole signal.

🔐

Rolling Code RF

Some RF remotes — car keys, garage doors, security systems — use rolling codes that change every press. These cannot be learned by design. This is a security feature. Fixed-code RF remotes (fans, blinds, gates) work fine.

🌡️

Carrier Frequency Matters

Most IR is 38kHz. Sony uses 40kHz. RC5/RC6 use 36kHz. If a learned code won't fire a device, try editing the carrier frequency in the Signal Stats panel. A wrong carrier is the most common cause of silent failures.

🚀

Signal Transporter — Move Codes Between Remotes

Got an old remote file you want to re-use on a new layout? The Signal Transporter handles the transfer — drop your old + new files side-by-side, click-pair the buttons, and download in any format. Works between .irc, Flipper .ir, LIRC, Pronto, BroadLink, Global Caché (iTach), GIRR, Harmony XML, Arduino .ino, and more.

RF Signal Tips

📡

11 Fixed-Code Protocols — Decode & Generate

Paste a Flipper Zero .sub file or a raw 433/315/868 MHz capture and it identifies the protocol and key: Princeton / PT2262 / EV1527, Nice FLO, CAME, Holtek HT6P20, Ansonic, Gate TX, Linear, SMC5326, BETT, Doitrand, Intertechno (Nexa / KlikAanKlikUit). Every one is validated against the Flipper firmware timing constants, and it auto-picks the tightest fit so a CAME never gets mistaken for a Princeton. Build one from a hex key in the RF Generator above, then export it as a Flipper .sub, an Arduino rc-switch sketch or an ESPHome raw block.

🎯

Rolling Codes — Identified, Not Faked

It recognises the common rolling-code families by their signature — KeeLoq, Chamberlain/LiftMaster Security+ 1.0 & 2.0, Somfy RTS, StarLine and Nice FloR-S — and tells you plainly when a capture is one of them. These change on every press, so no honest tool can clone them; READYWARE labels them instead of pretending.

🔒

Rolling Codes — Cannot Be Cloned

Garage doors, car key fobs, and security systems use rolling codes that change every single press. This is a deliberate security feature. You cannot learn or replay these. Fixed-code RF devices (fans, outlets, blinds, cheap gates) work fine.

📻

433.92 MHz — The Most Common

The vast majority of cheap RF remotes — ceiling fans, power outlets, motorized blinds, simple gates — use 433.92 MHz OOK. If you don't know your frequency, start here. BroadLink RM4 Pro learns and replays these natively.

🇺🇸

315 MHz — Older US Devices

315 MHz is common in older US-market devices — some garage door openers, older ceiling fan remotes, and automotive accessories. The RM4 Pro supports it. Use the 315 MHz preset when learning or replaying these.

🇪🇺

868 MHz — European / Z-Wave

868 MHz is the European ISM band. Used by Z-Wave smart home devices, some Somfy motorized blinds, and European RF remotes. Less common for simple devices. BroadLink RM4 Pro supports it.

📶

Interference — Learn in a Quiet Spot

433MHz shares spectrum with WiFi harmonics, microwave ovens, and baby monitors. If RF learning is flaky, move away from your router and other 2.4GHz devices. Learning outside or in a different room often fixes it instantly.

📏

RF Range vs IR Range

RF doesn't need line of sight — it goes through walls. Hold the remote 6–12 inches from the BroadLink RM4 Pro for learning (same as IR), but once learned it will fire from anywhere in your home. That's the power of RF automation.

        ▸ DENON / MARANTZ AVR CODES — how to use (optional)
      Denon & Marantz publish their remote codes as binary spec sheets, not ready-to-use hex. This tool turns them into Pronto, Flipper, BroadLink, .irc — whatever you need. You do not need any of this for normal remotes; it's only for these AVR sheets.
Have an “RCKSK…” code? (e.g. RCKSK0410348) → just paste it into the box above and hit Analyze. Paste a whole list to convert them all at once. These are the 48-bit Denon-K (Kaseikyo) codes.
Have an “RCSHP…” code? (e.g. RCSHP0230001 100000 POWER) → paste the row (label + its bits). These are the 15-bit Denon/Sharp codes.
Only have a bit row? Paste the 0/1 line straight off the PDF (e.g. 0 0 1 1 1 0 1 0 1 0) — stars/parity columns are ignored automatically.
Building a full set? Use the Protocol Generator above: pick Denon-K (Kaseikyo), leave D=4 / S=1, set F 0→1023, Generate — the whole command set comes out named. For older 15-bit units pick Denon or Sharp.
Try the DENON RCKSK / DENON RCSHP sample buttons under the paste box to see it work. Output matches Denon's published Pronto exactly.
