11 INFRARED

Infrared Mode

This mode allows communication using infrared signals to send and receive remote control commands.
It supports sending specific codes, learning signals from remotes, broadcasting Device-B-Gone codes, wide protocol selection, and universal remote builtin.

🧩 Commands

Arguments in < > are required, while arguments in [ ] are optional.

Command	Description
send <dev> <sub> <cmd>	Send an IR command with current protocol, device, sub-device and command (check IRDB for a wide list of remotes data)
receive	Listen for incoming IR signal and decode it or see it raw
setprotocol	Choose from 83 supported IR protocols (NEC, Sony, RC5, etc.)
devicebgone	Send a sequence of IR commands to power off TVs, projectors, boxes...
remote	Launch an interactive shell to universal remote control features
record	Interactively record IR signals and save them to a .ir file using LittleFS storage
load	Load and select remote .ir files from the LittleFS storage
replay [count]	Records up to 64 frames and replay them with original delays in between
jam	Transmits infrared bursts to evaluate how well an infrared receiver handles noise
config	Configure IR TX and RX pins

---

📂 Load (.ir files)

The load command uses infrared remote files from the Flipper IR DB.

How it works (quick start)

1. Upload the file(s)
   In the Web UI, open Files → LittleFS and drop your .ir files.

2. Load from the device
   In INFRARED mode, run:

   load

   • Pick a .ir from the list.
   • You can send frames by selecting the index.

3. Send
   Use the file’s metadata (frequency, preset, protocol) to send the command.
   If multiple commands are present, you can iterate and replay as needed.

📝 Notes

• send uses the current protocol defined in setprotocol and repeats the command 3 times.
• receive continuously listens for IR signals and displays the protocol + data when valid.
• devicebgone loops through a list of known "off" commands from 83 common IR protocols.
• remote opens an interactive menu to blast common keys (VOL, MUTE, POWER...) across many protocols (200 commands per action). Use Enter to stop early.
• replay asks you to record frames, once it's done, press ENTER to replay them. Optional replay count.
• setprotocol displays a list of all available protocols and lets you choose one, it will be used with send.
• config allows you to set which GPIOs are used for IR transmit (TX) and receive (RX).
• load works with .ir files from https://github.com/Lucaslhm/Flipper-IRDB
• record asks for function name and save up to 64 frames using flipper zero IR file format.
• jam prompts for mode, carrier frequency (khz), and transmission density before running.
• See https://github.com/probonopd/irdb for a massive database of IR remotes (device subdevice function) to use with the send command

📌 Example Usage

mode infrared
config                     # Set TX and RX pins
setprotocol                # Select a protocol (e.g. NEC, Sony)
send 0 0 64                # Send command (device=0, sub=0, command=64)
receive                    # Wait for and decode IR signals
remote                     # Open an universal remote shell
replay                     # Records up to 64 IR signals and replay until ENTER is pressed
load                       # Load .ir remote files from the NVS and select the one you want
replay 10                  # Records up to 64 IR signals and replay 10 times or until ENTER is pressed
jam                        # Spam random infrared signals
devicebgone                # Try turning off all nearby devices
