Bluetooth LE protocol analysis on professional wideband capture equipment
Every advertising and data channel is captured simultaneously, timestamped precisely and decoded from the link layer to the application profile. I use it to isolate connection, timing and interoperability faults that are difficult to pin down with entry-level sniffers.

Engagements are limited to Bluetooth Low Energy, analyzed over the air.
- Wideband BLE capture
- All-channel capture that does not join or disturb your devices, so you see real behavior and not the behavior of a test setup.
- Connection establishment and stability
- Root-cause analysis of failed connections, unexpected disconnects, supervision timeouts and connection parameter negotiation problems.
- Pairing and security procedures
- Review of Security Manager flows, bonding behavior, key distribution and re-encryption to find why pairing fails or is repeated.
- ATT and GATT behavior review
- Verification of service discovery, characteristic access, notifications and indications against the specification and your firmware design.
- Link-layer timing and throughput
- Measurement of connection events, retransmissions and packet loss to explain low throughput, latency spikes and radio-related power consumption.
- Interoperability investigation
- Reproduction and documentation of faults between your product and specific phones, hubs or third-party peripherals, with evidence suitable to send to another vendor.
- Advertising and scanning analysis
- Assessment of advertising intervals, payload content, scan response behavior and the information a device exposes over the air.
- Engineering training
- A hands-on session that teaches your team to read BLE traces and diagnose protocol problems independently.
- Deliverables
- A written findings report, annotated capture files and specific recommendations for firmware or configuration changes.
Engagement process
A defined process with clear outputs at each stage.
- ScopingYou describe the symptoms, hardware and test conditions. I confirm whether BLE analysis can address the problem.
- Capture and analysisThe faulty behavior is recorded, then traced layer by layer to a root cause.
- ReportingYou receive the findings, annotated captures and recommended corrective actions.
Scope of work
Services cover Bluetooth Low Energy over-the-air analysis only.
Other Firmware development available.
