Common mistakes

These cause most first-run problems.

Installing eeg-web-ble without eeg-web. The Bluetooth transport depends on it.
Expecting Web Bluetooth in Safari or on iOS. Use Chrome or Edge on desktop or Android. See Compatibility.
Serving over plain http://. Camera and Bluetooth need https:// or localhost.
Assuming a scaffolded app is broken inside another pnpm workspace. Install it with pnpm --dir my-app --ignore-workspace install.
