# a2854-siri-remote-linux: reconstructing Siri Remote BLE and IR controls

> a2854-siri-remote-linux reconstructs Apple Siri Remote A2854 button and voice notifications for a Linux bridge that reads btmon output. It documents GATT button values, a 100-byte Opus audio wrapper, and an IR provisioning sequence observed through HID reports; separate research examines the remote's flash image and IR database.

## Requirements & limits

- **Prerequisites:** An Apple Siri Remote 3rd generation A2854 and a Linux host with Bluetooth are required for the bridge.
- **Prerequisites:** The documented rig uses Ubuntu 24.04, BlueZ 5.72 and btmon access.
- **Limits:** The left d-pad button value was untested; the investigated appliance did not respond to the IR approximation.
- **License:** MIT License.
