BLE LED Matrix Controller: reconstructing GIF upload for a 96×20 display

BLE LED Matrix Controller investigates the BLE commands of an ATOTOZONE CI-VIALD19 96×20 LED matrix and supplies a Python uploader for GIFs and static images. Its notes record packet acknowledgments and commands for brightness and screen blanking; the author reports successful GIF uploads below 49,980 bytes.
