Deli XiangYinBao X1: reconstructing a Bluetooth label printer protocol

Deli XiangYinBao X1 reconstructs the portable label printer's proprietary Bluetooth printing protocol from HCI captures and Frida observations. It documents CRC32 framing, 384-dot bitmap encoding, replies, and print sequencing, with Python and JavaScript implementations, capture parsers, and regression tests.
