No Off-screen UI rendering, real-time video encoding, and streaming to a bare-metal microcontroller smartwatch over BLE or serial requires deep embedded systems and low-level firmware engineering.
What it would actually take: The architecture requires an Android Kotlin app rendering UI to an off-screen surface buffer, encoding frames using low-overhead compression (such as lightweight JPEG or custom RLE), and streaming packets over Bluetooth Low Energy/UART to an MCU running FreeRTOS or bare-metal C. The hard part is achieving low-latency streaming and touch responsiveness while respecting the severe bandwidth, memory, and SPI display controller limits of an MCU. This demands specialized expertise in embedded C firmware, display protocols, and mobile hardware acceleration.
