Hi, this is a narrowly scoped Bluetooth debugging problem, and the key issue is not pairing itself but identifying the exact layer that triggers fallback away from the intended two-way audio path. I’ve worked on production systems where the hard part was isolating failure boundaries across app logic, media routing, and device behavior under live conditions. In a case like this, I would treat Android 16, the OEM build, and the earbud firmware as separate fault domains and verify where the mode transition actually occurs rather than assuming the application is the cause. The closest relevant work in my background is TikTok AI Livestream Setup, where I had to stabilize low-latency audio routing across multiple moving parts, and Custom Feature Development & Integration, which reflects how I enter live systems, inspect behavior, and narrow root causes quickly. I usually structure this kind of investigation as evidence first: reproduce, capture traces, compare successful versus fallback sessions, then map the break to negotiation, routing, or device capability exposure. If useful, I can start by reviewing the current reproduction flow and outlining a fault-isolation plan for the fallback behavior. Thanks, Hercules

@leonidye

Hi, I can help debug your Android LE Audio LC3 Unicast issue and identify why the Sony WF-1000XM6 connection is falling back to Classic Bluetooth instead of maintaining stable two-way LE Audio. This is clearly a low-level Bluetooth/audio-stack investigation, so my approach would start with confirming whether LC3 Unicast, BAP/PACS/ASCS negotiation, CIS/ISO transport, and the expected audio route are actually active on the OnePlus and POCO Android 16 devices. I can analyze BTSnoop/HCI logs in Wireshark, compare successful and failed connection sequences, and isolate whether the fallback is triggered by earbud capability exposure, Sony firmware behavior, Android Bluetooth HAL, OEM Qualcomm/Bluetooth driver implementation, or application-level routing. I have experience with Android Bluetooth internals, BLE/LE Audio debugging, HCI trace analysis, audio framework behavior, and device-level fault isolation, and I can provide specific prior examples in chat. The deliverable will be a clear technical report showing the evidence, root-cause hypothesis, recommended fix path, and any implementation changes needed to keep the system on LE Audio rather than A2DP/HFP. Please share the BTSnoop logs, device build numbers, Sony firmware version, reproduction steps, and current app/audio-routing flow so I can begin with a focused trace review. Regards.

@tetianam8

⭐⭐⭐⭐⭐ I've reviewed your requirements carefully, and this is clearly a specialized Bluetooth debugging project rather than general Android development. My approach would begin with a structured analysis of the BTSnoop/HCI logs to verify whether LE Audio (LC3 Unicast) negotiation is occurring, identify where the connection falls back to Classic Bluetooth, and isolate whether the limitation originates from the Android Bluetooth stack, OEM implementation, device firmware, or application behavior. I'll document the findings and recommend the most practical path forward based on the evidence. Before moving ahead, I'd like to clarify a few details: • Can you provide BTSnoop/HCI logs from both affected devices? • Is the issue reproducible with multiple LE Audio-capable earbuds or only the Sony WF-1000XM6? • Is root access or an engineering build available for deeper Bluetooth diagnostics? I look forward to reviewing the logs and helping identify the root cause efficiently.

@rosscarter1011

Hey, the fallback to A2DP/HFP is the classic headache with LE Audio — usually the stack negotiates down the moment CIS establishment hiccups or PACS capability exchange doesn’t go cleanly. I’d start with BTSnoop to trace exactly where the fallback decision happens — HAL layer, OEM stack, or Sony firmware side — before touching any code. I’ve dug into Android Bluetooth HAL internals and BAP/ASCS flows, so I know how messy OxygenOS and HyperOS can be with LE Audio compliance. Have you captured a BTSnoop log yet, or would that be the first step together?

@jagratip3

Dear Hiring Manager, I am an Android engineer with strong experience in low-level Bluetooth stack debugging, audio pipeline analysis, and system-level Android development. I have worked on complex Bluetooth integrations involving HCI/BTSnoop log analysis, audio routing issues, and OEM-specific behavior across different Android builds. I understand this is not a general app development task. Your project requires deep investigation of **LE Audio (LC3 Unicast), BAP/ASCS/CIS flows, and Android Bluetooth HAL behavior**, especially around fallback conditions to Classic A2DP/HFP. I can help you: • Analyze BTSnoop/HCI logs to confirm LE Audio activation • Identify why devices fall back to Classic Bluetooth • Debug Android Audio Framework + Bluetooth stack interactions • Isolate whether the issue comes from OEM drivers, Sony firmware, or app-level configuration • Provide actionable fixes or architecture adjustments I have previously worked on Bluetooth audio routing, latency optimization, and protocol-level debugging on Android systems using logcat, Wireshark, and internal audio traces. I am comfortable working with deep technical stacks and collaborating on iterative debugging cycles until root cause is fully identified. I am ready to start immediately and begin with log analysis and system verification. Best regards, JP

@MuhammadUzair16

Hi I am an embedded systems/Bluetooth engineer with over 16 years of experience, including hands-on debugging of Android Bluetooth and audio paths where LE Audio behavior must be proven from logs rather than UI indicators. I have worked with LE Audio/LC3 bring-up and troubleshooting, Android Bluetooth internals, Bluetooth HAL interactions, BTSnoop/HCI captures and Wireshark analysis. For this project I would first verify whether LC3 Unicast is really being negotiated with the Sony WF-1000XM6 on the OnePlus and POCO devices, then trace why the session falls back to Classic Bluetooth. The useful output will be a clear root-cause direction: Sony firmware limitation, Android/OEM stack behavior, Qualcomm driver issue, audio framework routing, or an application-level constraint. I can review BAP/PACS/ASCS behavior, CIS/ISO setup, codec capability selection and simultaneous playback/microphone routing, then recommend or help implement the practical fix. I have also worked with Sony Bluetooth devices and have analyzed BTSnoop/HCI logs before. Previous LE Audio and LC3 work cannot be shared publicly due to client confidentiality, but I can discuss relevant details privately. Please contact me to discuss the device setup, available logs, and what has already been tested.
