# allmiibo-sync: reconstructing Pixl.js Bluetooth file synchronization

> allmiibo-sync reconstructs the Pixl.js and AmiiboLink Bluetooth LE virtual filesystem protocol to synchronize folders with NFC emulator devices. Its browser app compares local and device trees, plans transfers and deletions, and uses VFS commands documented from official web clients and checked against firmware.
