VS Code Extension · Free & Open Source
Your Firmware Logs Deserve
Better Than a Terminal
LogScope turns your embedded firmware logs into a structured, filterable timeline — right inside VS Code. Supports Zephyr, nRF5 SDK, and raw output with Bluetooth LE HCI decoding. Connect via J-Link RTT or Serial UART.

Everything You Need to Debug Smarter
LogScope turns your raw log stream into a structured, searchable, decodable debugging experience.
Multi-Parser Support
Zephyr RTOS, nRF5 SDK, or raw mode. One tool for any firmware — just pick your parser and connect.
Deep HCI Decoding
14+ packet decoders. See connection parameters, PHY changes, ATT operations — not hex dumps.
Host Timestamps
Wall-clock time on every log line. Correlate firmware events with real-world timing, even without device timestamps.
Search & Filter
Severity toggles, module filtering, and full-text search. Find that one error in thousands of lines.
RTT & UART Transport
Connect via J-Link RTT for zero-loss streaming with HCI decoding, or Serial UART for USB CDC ACM and UART bridges.
Flexible Export
Export as text (with host timestamps), JSON Lines, or Wireshark btsnoop. Share logs or feed them into scripts.
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.
Up and Running in 60 Seconds
No complicated setup. No external tools. Just install, connect, and debug.
Install
Search “LogScope” in the VS Code Marketplace and install the extension.
Connect
Plug in your dev kit and click Connect. Choose J-Link RTT or Serial UART — LogScope auto-discovers your devices and ports.
Debug
Logs stream in real-time with filtering, search, and full HCI decoding.
How LogScope Compares
You don't have to choose between readable logs and protocol analysis anymore.
