Hello, i can change the text to "connected" and background color to "green" when bluetooth is connected but when i unplug the bluetooth receiver then it doesnt change the text to "disconnected" and background color to "red". neither this [1] nor this work [2] what am i doing wrong? thanks in…

This went into AI2 last night in nb183: Add DisconnectOnError property to BluetoothClient See the release notes at http://appinventor.mit.edu/ai2/ReleaseNotes.html It might be just what you need, if combined with polling the BlueTooth connection by trying to send regularly.
