## Send a saved command
- Open Infrared and browse Remotes to see saved .ir files.
- Pick a Flipper-compatible .ir file. GhostESP parses the sections inside the file and lists every named button.
- Tap a button entry to transmit. The configured LED should flash pink if not in stealth mode.
Tip: If you see “No .ir files” in the Remotes or Universals lists, try reinserting your SD card and rebooting the device. Ensure the /mnt/ghostesp/infrared/remotes and /mnt/ghostesp/infrared/universals folders exist on the card.
### Universal libraries
- Universal .ir packs live under /ghostesp/infrared/universals and contain large collections of commands grouped by device.
- When you open a universal file, GhostESP scans the command list and prompts you to pick a specific button to send.
- Parsing very large libraries (for example, community dumps) can take several seconds; wait for the list to finish populating before selecting.
- You can find supported universals at [Momentum Flipper Firmware](https://github.com/Next-Flip/Momentum-Firmware/tree/dev/applications/main/infrared/resources/infrared/assets). Download and place the files under infrared/universals.
GhostESP also includes a built-in Universal IR file with popular TV POWER signals. Use the TURNHISTVOFF universal to turn on or off many different TVs.
### Tips
- Aim the LED directly at the target’s receiver window.
- If nothing happens, close the popup, verify you chose the right protocol (raw vs decoded), and relearn the button or test another signal.
- Ensure no bright sunlight hits the receiver; ambient infrared noise can reduce range.
## CLI Support
You can transmit signals using the command line interface, which is useful for scripting or automation.
### Sending from file
Use ir send to transmit a signal from an existing .ir file:
# Send the first signal in the file
ir send /mnt/ghostesp/infrared/remotes/TV.ir
# Send the 3rd signal (index 2)
ir send /mnt/ghostesp/infrared/remotes/TV.ir 2
### Inline Sending
You can send raw or parsed signals directly without a file using the inline mode markers. This is useful for sending commands from a script or external tool.
