Insta360 x5 Bluetooth Classic Sniff & Analyze
Budget: $30 – $250 USD
I need an experienced Bluetooth-Classic analyst who can hook up an Ellisys BR/EDR sniffer to my setup and hand me clean captures of everything that happens between an Insta360 X5 camera and its Mic Air wireless microphone.
Here is where I am right now
• I have proved that the camera pairs over BT-Classic, not BLE.
• Using an ESP32-A1S I can reproduce the pairing, yet the moment I start recording I hit a short audio glitch and the entire recording stops.
What I must understand
• Full packet-level flow for both the initial pairing and the ongoing A2DP + HFP/HSP streaming sessions.
• Any proprietary commands, timing quirks or role switches that might be triggering the audio anomaly and shut-off.
Your tasks
1. Capture both pairing and streaming protocol data in separate, well-labeled Ellisys trace files.
2. Decode each phase, annotate the HCI/LMP/L2CAP layers, and flag anything that deviates from the Bluetooth spec.
3. Summarise the root cause you see for the glitch and recommend concrete changes I can apply (e.g. timing tweaks, codec negotiation, extra AT commands).
Deliverables
• Raw Ellisys capture files (.bqb / .bts).
• A written walkthrough of the packet sequence with problem areas highlighted.
• A concise fix or test plan I can run on my ESP32-A1S to confirm stability.
I am ready to ship you both devices if needed, but if you already have equivalent hardware and can recreate the scenario faster, even better. Please indicate estimated turnaround and any extra tools you plan to use alongside Ellisys (Frontline, Wireshark, custom decoders, etc.).
