The script, which was reverse-engineered from Creative's Windows desktop app, sends specific configuration data arrays to the USB dongle to toggle between the two modes. It is designed for use with AptX Adaptive-compatible headphones, such as the Tranya X3, and requires either sudo privileges or adjusted USB device permissions to run.", "body_md": "btw5-switch.py\n\n      This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below.
