Downloading Logs

Log data is downloaded from the OnSpeed controller via WiFi.

Via WiFi Web Interface

1. Connect to OnSpeed WiFi (OnSpeed / angleofattack)
2. Navigate to http://192.168.0.1/logs
3. The page lists all log files on the SD card with sizes
4. Click a filename to download it

Logging pauses during download

SD card logging is temporarily paused while a file is being downloaded to prevent conflicts. It resumes automatically after the download completes.

Download Speed

WiFi transfers are not fast — the ESP32's WiFi bandwidth is limited. A large log file (50–100 MB) may take several minutes to download. Stay close to the controller for the best signal.
