| To clarify: I can recreate this problem by doing a device inquiry with BT, turn BT off inquire again, turn BT back on and inquire again. The callback set by IOBluetoothDeviceInquirySetDeviceFoundCallback() is never called.
I'm not sure how to work around this or what's causing it...
--Daniel We have a pretty reliable BT implementation. The problem I'm having is after you successfully use BT, if you then disable it (from the system toolbar), and then reenable it, I get the following behavior:
I am using IOBluetoothDeviceInquirySetDeviceFoundCallback().
When this is called, I set a counter, as per the bt examples in the manual.
After I disable/enable BT, this never gets called. However, if I stop my application and restart it, everything works fine.
Is there something I need to do in this case to reset a state or something? I'm using IOBluetoothLocalDeviceGetPowerState() to discover when BT is available to me. When it's not available I abort my inquiry. Perhaps I'm leaving some state somehow that's causing this problem?
