Hi Sam, I had the same issue. I implemented a CBCentralManager and a CBPeripheralManager in my application. To test it out I used the TimeApp that ships with the CC2540 Development Kit. That is a watch client, and it connects to my central manager, and updates the current time from the Time service.

The Time Server requires to be GATT Server and GAP Central. If i understand good, CBCentralManager & CBPeripheral are for GAP Central & GATT Client. And CBPeripheralManager & CBCentral are for GAP Peripheral & GATT Server. So, it's not possible? or i need to use both CBCentralManger and CBPeripheralManager in my app?
