CBPeripheralManager's delegate won't handle connection?

Hi, While in the background mode, it seems CBPeripheralManager will keep advertising, but it cannot handle the read request from other devices? The delegate won't be called. Is that I missed something? Best Wishes, Khaos Tian _______________________________________________ Do not post admin requests to the list. They will be ignored.
