iM.Master SDK: reconstructing the robot's BLE control protocol

iM.Master SDK reconstructs the iM.Master toy robot's BLE advertising commands and exposes them through a Python control API. Its protocol notes describe a 14-byte manufacturer payload under company ID 0x53A6, recovered from vendor-app captures, while the driver streams frames through Linux raw HCI to move the robot.

Requirements & limits

Prerequisites: Python 3.10 or newer; moving the iM.Master robot requires Linux raw BLE HCI, in practice a Raspberry Pi run as root.
Scope: The protocol layer can build and decode frames without hardware on Windows, macOS, or Linux.
