Edit: the pink LED is AptX High. AptX Lossless makes LED yellow. The mode and command is the same |

Tested on my Linux laptop and it works! Recorded a short video showing this (it's uploading as I write this). |

Love the project! As someone who uses all three operating systems (MacOS at work laptop, Linux on personal machines, Windows on gaming rig) and dislikes that Creative app is available only on two of those, and I'm allowed to install it only on the Windows machine.
I've spent an evening with my recently bought Creative BT-W6, Aurvana Ace 2 headphones, Wireshark and AI Agent (playing around with OpenClacky and various models via OpenRouter) because I don't know much about using Wireshark. So this PR is mostly slop. The PR description is human written!
My Aurvana Ace 2 can connect with BT-W6 dongle using at least 3 protocols: Bluetooth Classic AptX Low-Latency (teal / light-blue LED on dongle), AptX High/Lossless (pink LED on dongle) OR Bluetooth LE Audio with LC3 codec (white LED).
Add BT-W6 support with LE Audio / LC3 and Bluetooth Classic modes
To the point.
This PR extends
btw5-switchto support the Creative BT-W6 dongle (041e:3132), adding two new modes: LE Audio (LC3) and Bluetooth Classic.Note
I wasn't sure if I should edit the original btw5 script or create a new one, btw6, alongside. So the support is right now as extension to btw5 script.
What's changed
0x3130) or BT-W6 (0x3132) by product ID, with BT-W5 checked first for backward compatibility.le— LE Audio with LC3 codec (03 5a 6b 03 0a 06 02)classic— Bluetooth Classic (03 5a 6b 03 0a 06 00)le/classicwhen a BT-W6 is detected).bt-w6.pcapng— a USBPcap recording of the Creative Windows app switching through HQ → LL → LE.How it was reverse-engineered
No public documentation exists for the BT-W6's HID protocol. The command payloads were extracted from Wireshark USBPcap captures of the official Creative Windows app, parsed with a custom Python pcapng reader (
/tmp/parse_pcap2.py) since tshark/wireshark wasn't available on the Linux machine. Multiple captures confirmed the same byte patterns across different switching paths.Verification
Actually pending, I'm going to test it on my Linux laptop and report back 🤞
