CAN Analyzer Wireless
An ESP32 CAN bus analyzer with no cable to the PC
The analyzer sits on your CAN bus and creates its own Wi-Fi hotspot. The desktop application joins that hotspot and shows you the traffic live — so the PC can sit several metres from the vehicle or test rig. It decodes raw bytes into named signals using a DBC file, filters by ID on the device itself, and records to a CSV on the PC, to a microSD card on the analyzer, or both. It will also log on its own with no PC present at all.
Downloads
About the Windows security warning. The application is not code-signed, so Windows will likely show a blue "Windows protected your PC" banner the first time you run it, and some browsers warn while downloading. This is expected and is not a sign that anything is wrong with the file.
To proceed, choose More info → Run anyway on the banner. If Windows added an Unblock tick-box under right-click → Properties, tick it and press OK. Both cases are covered in the troubleshooting section of the guide.
