Anyway the device is misbehaving if it is sending suspend and start commands like that (perhaps you are pressing play/pause buttons?) but if you don't wan't the stream to auto suspend you just need to Acquire when the transport is in pending state. -- Luiz Augusto von Dentz -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
