Not sure what this is? That's OK — you probably don't need it.
If you're just using the READYWARE universal remote control app on your phone or tablet, everything happens in the app automatically. Pick your device, pick your brand, customize your buttons and layout, and you're done.
This page is for power users, tinkerers, hobbyists, developers, pro installers — or anyone moving from another platform or needing to convert a signal to a different format.
If you're coming from a Flipper Zero, BroadLink, Arduino project, LIRC setup, Home Assistant, Global Caché, and more — or just want to dig into raw IR/RF signals — you're in the right spot.
Convert between all the major formats, edit waveforms live, search 700,000+ codes, and load, save, or convert anywhere — all in your browser. Full featured. Completely free. No account. No install. Works on any device. Enjoy.

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.

Bluetooth IR Bridge
Convert BT remote signals to IR/RF
📱 BT HID REMOTE
Bluetooth HID remotes (Apple TV, Google TV, Android TV remotes) send standard HID keycodes. Map any HID keycode to an IR command.
📡 BT → IR BRIDGE
Use a BroadLink RM4 Pro or ESP32 as a bridge. Receives BT HID commands and fires the mapped IR signal automatically.
No mappings yet. Select a BT key and map it to an IR signal above.
ℹ️ BT REMOTE TYPES
■ BT HID — Apple TV, Google TV, Android TV remotes. Fully mappable here.
■ BT LE — BLE-based smart remotes. Proprietary protocols, device-specific.
■ Rolling Code RF — Garage doors, car fobs. Cannot be cloned by design.
■ BT Audio remotes — Use AVRCP profile. Map AVRCP commands to IR below.
Any BT-to-IR mapping exported here loads directly into READYWARE app as a macro — BT event fires the mapped IR signal.
