ir-bt-bridge

ir-bt-bridge turns any IR remote into a Bluetooth (BLE HID) remote for Google TV. An ESP32-S3 receives the remote’s IR codes, looks each one up in a keymap and sends the mapped key to the TV as a paired Bluetooth remote.

[Any IR Remote] → [IR receiver] → [ESP32-S3] → [BLE HID] → [Google TV]

                        [USB-C] ←→ [irbt CLI / library on a PC]

The keymap is edited over USB at runtime, so changing it needs no reflash. Use the irbt command-line tool, or the irbt Rust library to script it.

This guide covers:

• Hardware: parts and wiring.
• Flashing the firmware onto the board.
• Installing and using the irbt CLI.
• Using the irbt library from your own Rust code.
• The wire protocol between the device and the host.
• The API reference of the published crates.

The source is at code.selu.dev/selu/ir-bt-bridge. Building from source is covered in its README.
