You're thinking that you call .startDiscovery() and then it starts discovering devices and tells you which there are. It doesn't work like that. Discovery can take a long time, tens of seconds into minutes. If your call to .startDiscovery() blocked until the discovery was finished, your program would ANR and crash.... Instead, when you call .startDiscovery() what happens is that you're asking the operating system "start looking for BT devices, when you finish looking for them, broadcast that you're done and I'll ask what you found, even though this will probably take a long time." So you need to register the BroadcastReceiver to handle the Bluetooth discovery finished action. Have you read the BluetoothChat example. I feel like if you had then you wouldn't be asking this, go read that and it should make sense. And if it doesn't then go read about what a BroadcastReceiver is in the first place. Basically: you're writing your code like it runs in a straight line, it doesn't, it runs asynchronously, so you have to structure your code differently. kris -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
