Hi
ich habe folgendes Problem. Ich verbinde einen GPS mit einem HTC-Hero (Android 2.1), beide Geräte sind gepairt. Über eine App lese ich kontinuierlich in einem Thread per BluetoothSocket Daten des GPS aus. Alles 2-4 Minuten erhalte ich eine IOException (Socket closed). Dann versucht sich die App neu zu verbinden, was nach 4-8 Versuchen auch wieder klappt. Danach beginnt das Spielchen von vorn, also wieder 2-4 Minuten Daten lesen, dann Exception.
Irgendetwas schließt selbstständig die Connection (nicht meine App)
In den Logs sind solche Verbindungsabbrüche immer wie folgt zu erkennen:

Weis jemand woran das liegen könnte?
