Better Than a Terminal

LogScope decodes your Zephyr RTOS logs and Bluetooth LE HCI packets into a structured, filterable timeline — right inside VS Code.

LogScope showing color-coded Zephyr logs with HCI packet decoding, module filtering, and real-time streaming in VS Code

Sound Familiar?

Scrolling through raw terminal output — hunting for one log line in a wall of text

Sensor logs burying your Bluetooth LE debugging — no way to filter by module

HCI packets as opaque hex — copying bytes into Wireshark just to read a connection event

Finding the needle in thousands of log lines — no search, no filtering, no way to jump to what matters

Everything You Need to Debug Smarter

LogScope turns your raw log stream into a structured, searchable, decodable debugging experience.

Module Filtering

Toggle log modules on/off. Focus on Bluetooth LE, hide sensor noise, or vice versa.

Deep HCI Decoding

14+ packet decoders. See connection parameters, PHY changes, ATT operations — not hex dumps.

Flexible Export

Export as text, JSON Lines, or Wireshark btsnoop. Share logs, feed them into scripts, or do deep protocol analysis.

Search & Filter

Full-text search across all log entries. Find that one error in thousands of lines.

Board Reset Detection

Automatic detection of device resets. Never wonder “did it reboot?” again.

100K Log Buffer

Ring buffer holds 100,000 entries. Scroll back through long debug sessions without losing history.

Built by a Developer Who Needed It

I've wanted to build this tool for over 10 years. After a decade of debugging Bluetooth LE firmware through raw terminal output, I finally sat down and built the tool I wished I'd always had — not for a product launch, but because I needed it myself.

LogScope is the debugging experience I always wanted: structured logs, decoded HCI packets, and real filtering — all without leaving VS Code. I hope it saves you as much time as it's already saved me.

Frequently Asked Questions

Any device with a J-Link debugger via RTT. Works with Nordic, NXP, STM32, and other J-Link-supported chips. More transports coming soon.

RTT Viewer shows you the raw byte stream. LogScope parses it into structured log entries, color-codes by module, decodes Bluetooth LE HCI packets, and lets you filter and search — all inside VS Code.

Yes. LogScope parses any Zephyr RTOS logs. The HCI decoding is a bonus for Bluetooth LE developers, but filtering, search, and export work for all Zephyr projects.

Yes, free and open source (MIT license).

Yes. One-click export to btsnoop format, which Wireshark opens natively for deep HCI protocol analysis.

Not yet. RTT is the only transport currently supported. UART support is planned.
